From f81a33d721906274e26cf63d8c873f73da39e203 Mon Sep 17 00:00:00 2001 From: ewowi Date: Fri, 21 Aug 2026 13:44:02 +0200 Subject: [PATCH 1/5] An LED driver could silently take an Ethernet pin MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A spare i80 bus lane was parked on a real GPIO, and on the S31 that pin is an Ethernet transmit line: every frame the MAC sent went out corrupt while the link reported 1000 Mbit with zero drops. Fixing it made both the LED panel and S31 Ethernet work for the first time. The pin map now shows the pads a peripheral holds without a control naming them. Performance: no tick-path change; the added work is one virtual call on the bus build path, never per frame or per light. Light domain - LedPeripheral::spareLanesNeedPad() (default true, false on MoonI80): esp_lcd rejects an NC data pin so it must park spares on a real pad, but a backend that routes its own GPIOs leaves them unconnected. busPinCount() now hands such a backend only the lanes a strand reads, so a one-strand board stops driving six or seven GPIOs it never asked for. Core - MoonModule::fixedPins(): the GPIOs a module holds that are NOT controls, which is how a silicon-fixed pad reaches the pin map. Reported only while the module uses them, so a board with ethType None spends those pins on LEDs; three of the four classic boards in the catalog have no PHY at all. - PinsModule asks every module for them. The map reads controls as the pin registry, and a pad no control names is a pad it shows free while a peripheral drives it. - NetworkModule reports the twelve RGMII pads from one platform::ethRgmiiPads list that ethInitEmac also reads, by name rather than by index so a reorder cannot rewire the MAC. They are not controls: nobody can choose them. - MDC/MDIO are shown on RGMII, not only RMII. ethInitEmac sets smi_gpio outside the interface branch, so an RGMII board drives them too; hidden, they were two more pins the map could not see. - The classic ESP32's default states MDC 23 / MDIO 18 rather than -1. The MAC used those either way (a -1 makes ethInitEmac skip smi_gpio and IDF applies the same pair), but -1 is invisible to the map. NOTE: a board with -1 already persisted keeps it; set them once or erase NVS. - The Ethernet status carries the negotiated link speed, so a gigabit PHY that fell back to 100M is visible rather than looking identical. Scripts/MoonDeck - grid.mll: cols/rows reach 128, so a scripted grid can fill 16384 lights. Tests - a peripheral that routes its own pins is handed only the lanes it drives. - the RGMII pad list's count matches its length (a static_assert where it is evaluated: hasEthernet is false on the desktop, so a host test of the control side would assert nothing). Docs/CI - docs/friend-repos/ holds the friend-repo digests, moved out of history/ with the digest prompt that generates them; a new Funkelfetisch/projectMM digest covers the fork building HELIO on this project. - backlog: the GPIO collision, the RMII data pins and the classic MDC/MDIO gap that remain open, and the S31 Ethernet entry DELETED: it blamed an RGMII Tx-clock mismatch since 2026-07-26, and the cause was this same pin. Reviews - πŸ‘Ύ Reviewer (Fable) over the staged diff, 8 findings. Fixed: a zero-size constexpr array that MSVC rejects (the Windows CI job compiles that header), a test that asserted nothing on the desktop, a positional pad-to-role mapping in two places, the digest-prompt links, four link labels, a stray blank line. Investigated and dropped: a scenario tick bound loosened 103 to 242 us, which re-measured clean on an idle machine, so the tighter bound stands. Left for the PO: `readonly` is a UI hint rather than a write gate, which is a core-wide question rather than part of this change.

Confirmed on hardware that this is **not a regression** β€” it fails identically at the original S31 bring-up commit `d5ee07c` built against its exact pinned IDF (`0d928780081` / v6.1-dev-5215). The firmware logs `Ethernet no IP (DHCP timeout), cascading` and falls back to WiFi. - -**The gigabit test ran (2026-07-27) and Ethernet still does NOT lease β€” the link-speed theory is in doubt.** This was the decisive experiment this item asked for, and the expected outcome (leases at 1000M, because TXC is already 125 MHz there) did **not** happen.

The host's ARP table lists the **WiFi** MAC and contains **zero** entries for the Ethernet MAC. A DISCOVER that reached the router would leave the eth MAC visible there even without a completed lease, so TX is not arriving β€” the same data-plane TX conclusion the static-IP test reached at 100M, now reproduced with a gigabit router in the path. - -**Physical-layer caveat, and the most likely explanation:** the jack's **yellow LED is off while green blinks fast**. On most RJ45 jacks yellow is the speed/link indicator, so yellow-off suggests the port did **not** negotiate 1000M and fell back to 100M β€” which would put this squarely back in the known TXC case rather than disproving it. This is unresolved because the firmware cannot currently report the negotiated speed: IDF logs `working in 100Mbps` / `1000Mbps` at `ESP_LOGD`, filtered out at our log level (exactly the diagnostic gap step (2) below names). **Before drawing any conclusion about the root cause, settle the actual link speed** β€” read the router's port page, and try a known 4-pair (gigabit-capable) cable, since a 2-pair cable forces 100M regardless of the router. - -**Root cause (IDF source-traced).** On RGMII the MAC's Tx clock (TXC) must be 125 MHz at 1000M but **25 MHz at 100M** (`emac_esp32_set_speed`). The MAC is reprogrammed only when the generic 802.3 PHY driver's poll sees a link_status *transition* (`updt_link_dup_spd` β†’ `on_state_changed(ETH_STATE_SPEED)`). Because the YT8531 needs its auto-negotiation manually re-enabled before `esp_eth_start` (it disables it on reset), the first negotiation can latch link-UP before the poll's first read, so the poll sees no transition, so `set_speed(100M)` never runs and TXC stays at its 125 MHz install default. At 100M every Tx frame then clocks out garbled and the switch drops it (Rx still works β€” it rides the PHY-recovered RXC): link up, DISCOVER sent, no OFFER ever. - -**Approaches tried on the bench (neither shipped):** -- **`esp_eth_stop()` + `esp_eth_start()` bounce after start** β€” DID produce the first-ever eth lease (`.125`), proving the mechanism, but `esp_eth_stop` tears the netif down (releases the lease, resets dhcpc to INIT, clears the IP), which races the NetworkModule 15 s cascade window and the double `applyHostname` β†’ non-deterministic (sometimes eth, sometimes WiFi; when eth, the netif IP was half-applied). -- **In-place `link_status = ETH_LINK_DOWN` + `phy->get_link()`** (netif-preserving, from the CONNECTED handler) β€” ran cleanly (no crash from the re-entrant poll) and forced a second link-up, but eth **still** DHCP-timed-out on the bench. Open question: whether `set_speed` actually fired (the `working in 100Mbps` proof line is `ESP_LOGD`, likely filtered by the esp_eth component log level β€” absence is not proof). - -**Already landed (the link-up half):** `ethYt8531BoardInit` (re-enables the YT8531's auto-negotiation β€” disabled on reset β€” plus the RGMII Tx/Rx clock delays) brings the RGMII **link** up (speed/duplex negotiated, activity LED lit); and the `ethPhyAddr` int16 fix (the `-1` auto-detect sentinel a `uint8` mangled to 31, with its regression test) makes the PHY addressable. What remains open is only the **100M Tx-clock (TXC) reconfiguration** so frames actually flow at 100M β€” the DHCP half below. - -**Next (needs hardware) β€” first, the gigabit test + a scope decision:** test the current firmware on a **1 Gb switch** (confirm `ETH-DIAG` reports "link up at 1000M full", then look for `Ethernet got IP`). At 1000M the MAC's Tx clock is already 125 MHz (the install default), so the 100M-specific TXC bug is absent β€” eth is expected to lease, matching the earlier field success on gigabit. **If it leases at 1000M, there is a product decision to make: whether to support 100M routers at all**, or to state that the S31 (a 1 Gb board) requires a gigabit switch and close this item as "won't-fix at 100M." Only if 100M support is deemed in-scope do the TXC steps below apply. - -**If 100M support is kept** (the TXC path): (1) if it links at 1000M but still no lease, sweep the RGMII delays (`MM_YT8531_{RX,TX}_DELAY`) for this board's trace lengths; (2) for 100M, add a decisive speed-readback diagnostic (`ETH_CMD_G_SPEED` before/after the resync + raise the esp_eth log level) to confirm whether `set_speed` runs; (3) if the in-place `link_status`-reset poke can't trigger `set_speed`, fall back to the stop/start bounce and make it deterministic by widening the S31 eth-DHCP cascade window (> 15 s) and suppressing the double `applyHostname`. - -**The failure is data-plane TX corruption, not a DHCP-handshake quirk (bench-confirmed 2026-07-26 via static IP).** Setting a static IP on the S31 at 100M bypasses DHCP entirely, yet the interface is still unreachable: ARP for the device resolves to the eth MAC (`30:ed:a0:f3:d4:68`) β€” so a broadcast round-trips β€” but unicast (ping / HTTP) is 100% dropped. That rules out "only the DHCP exchange is broken" and pins it to garbled unicast frames on the 100M Tx path (the TXC issue). So static addressing is NOT a workaround for 100M; the TXC fix (or a gigabit link) is genuinely required. **This is a bug to FIX, never a reason to weaken the AP β†’ STA β†’ ETH promotion cascade** β€” Ethernet always outranks WiFi when a cable is present, unconditionally. Interim behaviour on the S31 at 100M with a cable in Static mode: it promotes to Ethernet (as it must) but can't pass traffic; the user recovers by unplugging the cable (link-down cascades back to WiFi). Acceptable only as a temporary state for this one board's open bug, not a design. - -**Related symptom β€” the "Ethernet detected: no address assigned" degraded warning is intermittent on the S31.** In DHCP mode, that warning is meant to appear when the eth link is up but leaseless past the 15 s window (`NetworkModule::ConnectedSta`). On the S31 at 100M it shows only *sometimes*, because the marginal 100M link *flaps*: each `ETHERNET_EVENT_DISCONNECTED` makes `tick1s()` reset `ethLinkUpAt_` (the degraded clock), so the 15 s threshold is often never reached. This is the same root cause (a bad 100M physical link), so it resolves when the TXC/link issue is fixed. Two robustness follow-ups if it's ever decoupled: (a) don't reset the degraded clock on a *brief* link blip (debounce link-down), and (b) note that a lower `check_link_period_ms` makes the flapping more visible β€” the default 2000 ms is deliberately kept (a 500 ms poll surfaced the flaps and suppressed the warning entirely). - ## Flaky unit tests: the AudioService sync suite contends on a fixed UDP port **Found:** 2026-07-27, caught by `premerge.py`; pinned to the exact cases by looping the suite and keeping the failing logs.

The card's own activity LED never blinked. Four firmware versions across two ESP-IDF releases behaved identically. + +The cause is a **GPIO collision that no part of the system could report**. `ParallelLed` carried `clockPin = 10`, and GPIO 10 is `txd2` on the S31's RGMII bus (`platform_esp32.cpp`: the EMAC's fixed IO_MUX pads are 8-19 plus MDC/MDIO on 5/6). The LED driver drove one of the four Ethernet transmit data lines, so every frame left the MAC counted-as-sent and arrived corrupt. Disabling the LED drivers fixed it instantly; moving the clock to GPIO 21 fixed it with all four drivers running. + +Three separate defects made this invisible, and each is worth fixing on its own: + +**1. Pins the map cannot see, because nothing declares them.** The shipped conflict soft-flag grades what modules *declare*, so an undeclared pin is invisible to it however hard the silicon drives the pad.

Verified on MM-S31: `gpio 10` reports as `ethTxd2`. +- ❌ **RMII data pins** (open): `ethInitEmac` leaves TX_EN/TXD0/TXD1/CRS_DV/RXD0/RXD1 at `ETH_ESP32_EMAC_DEFAULT_CONFIG()`, so nothing names them. Confirmed on MM-P4, whose map lists MDC 31, MDIO 52, clock 50 and reset 51 (all controls) while the MAC also drives 49/34/35/28/29/30. +- ❌ **MDC/MDIO on the classic ESP32** (open): the chip default is `mdc -1, mdio -1` and neither Olimex model sets them, so `ethInitEmac` skips the assignment and IDF applies its own defaults (23/18). The controls show -1, the MAC drives 23 and 18, and the map claims neither. Verified on MM-Olimex: Network owns only `ethRstGpio 5` and `ethClockGpio 17`. Giving the classic the real numbers in `ethConfigDefault` (or in the two models' JSON) closes it, since the controls are already visible for RMII. + +**The fix is the RGMII one, extended.** Being fixed in silicon does not make `gpioCapability`'s reserved list the right home: reserved means "routing I/O here corrupts the device" (flash, PSRAM, USB), which is unconditional, while an EMAC pad is only held while that interface runs. With `ethType = None` the init returns false and every one of those GPIOs is free for LEDs, so a static reserved list would permanently forbid pins a WiFi-only board can use. What makes a control the right shape is not that the pin is configurable (it is not) but that the claim is CONDITIONAL: published when the interface is selected, released when it is not, which is exactly what the pin map reads. + +So the same `platform::ethRgmiiPads` treatment applies, with one wrinkle. On the **classic ESP32** the RMII data pins are silicon-fixed, so a second per-chip pad list serves them directly. On the **P4** 49/34/35/28/29/30 is the Waveshare NANO's *board* wiring that the IDF macro happens to default to, not a chip constant, so those belong in `deviceModels.json` beside the other per-board eth pins, letting a different P4 carrier declare its own. Both then reach the pin map through the control path already built, rather than a third mechanism. + +Lower risk than the RGMII case (six pins rather than twelve, and nothing of ours currently collides), but the failure mode is identical: a driver claims one, the MAC still reports a healthy link, and every frame goes out corrupt. + +**2. `busPinList()` pads spare lanes with `clockPin`, and MoonI80 routes them as data.** The i80 bus is always 8 or 16 bits wide (`ParallelLedDriver::busWidthPins`), so a board driving one strand gets seven lanes parked on the clock pin, and `configureGpio` (`platform_esp32_moon_i80.cpp`) routes every entry it is given. The padding exists because `esp_lcd` rejects an NC data pin, but the MoonI80 backend does not have that limit: its own comment says *"pins past `laneCount` go nowhere"*. It is simply never told the real lane count. Passing it would free six or seven GPIOs on every direct-mode board and remove the hidden claim at the source. + +**3. `clockPin` defaults to 10 and is hidden.** `MoonLedDriver::clockPin = 10` is a hardcoded default that lands inside the S31's reserved RGMII block, and `addBusControls` hides the control unless `pinExpanderMode()` is on. So on this board the value was invisible on the card, unchangeable through the UI, and still driving a pad. A pin with a real effect must be visible, whatever mode it is in. + +**This also closed the S31 Ethernet defect, open since 2026-07-26.** That entry (removed) blamed an RGMII Tx-clock mismatch at 100M for DHCP never completing, and had concluded "the frames never reach the router". The cause was the same collision: `ParallelLed`'s default `clockPin = 10` is `txd2`, so a DHCP DISCOVER was garbled exactly as the panel frames were. With the clock pin moved off the RGMII block the S31 leases normally, verified on the bench at `Eth: 192.168.1.125 (1000 Mbit)`.

Modelled on [leddriver-analysis-bottom-up.md](../history/leddriver-analysis-bottom-up.md). ## TL;DR @@ -11,7 +11,7 @@ - **The front-end is portable; the back-end is not.** Tokenizer + parser + AST (`NodeToken`) are CPU-agnostic; only the *visitor β†’ opcode* tier and the *load-and-execute* tier are ISA-bound. But today they're **deeply interleaved** β€” visitor methods emit Xtensa strings inline, there is **no intermediate representation (IR)** between AST and machine code. A clean redesign's load-bearing decision is whether to introduce that IR seam so one front-end feeds many back-ends (the LLVM shape, scaled down). - **The "compatible with MoonModule" requirement is the projectMM-specific value-add.** ESPLiveScript binds to the host via `addExternalFunction(name, ret, sig, fnptr)` / `addExternalVariable(name, type, _, ptr)` (`asm_external.h`) β€” a flat C-pointer registry. projectMM needs scripts to read/write **controls**, consume the **producer/consumer data structures** (a `Buffer`, an `AudioFrame`), and slot into the **module tree** as a scripted effect/layout/modifier/driver/peripheral. That binding layer β€” script ⇄ MoonModule β€” is ours to design; no surveyed engine has it. - **Memory + sync are already partly modelled in ESPLiveScript** and align with projectMM's constraints: compiled code lands in IRAM/PSRAM by target (`execute.h:10-15` gates PSRAM stack on S3/P4), a **save/load compiled-binary path** exists (`savebinary`/`executebinary` examples β†’ compile once, ship the binary, skip re-compile on boot), and a `sync()` primitive coordinates concurrent script tasks. These are the right *ideas*; the redesign carries them forward against our `platform::` seam and `Scheduler`. -- **⚠️ Superseded upstream (noted 2026-08-06): hpwit has rewritten it as [ESPLiveScript2](https://github.com/hpwit/new-parser).** A from-scratch C++ reimplementation whose stated goal is precisely the gap this analysis identified below β€” a compiler you can *verify*: the whole toolchain builds and runs as a host program, and its tests execute the actual compiled Xtensa bytes under QEMU against v1's own example corpus. The rewrite landed in the first days of August 2026 (the repo was dormant May 2025 β†’ August 2026), so this document's reading of v1 stands as written but is no longer a reading of hpwit's *current* work. **Before Stage 2 acts on any v1 conclusion, re-read v2** β€” the portability finding in particular (is codegen still Xtensa-only, or did the rewrite introduce the IR seam we concluded was missing?). Digest: [hpwit-new-parser.md](../history/hpwit-new-parser.md). +- **⚠️ Superseded upstream (noted 2026-08-06): hpwit has rewritten it as [ESPLiveScript2](https://github.com/hpwit/new-parser).** A from-scratch C++ reimplementation whose stated goal is precisely the gap this analysis identified below β€” a compiler you can *verify*: the whole toolchain builds and runs as a host program, and its tests execute the actual compiled Xtensa bytes under QEMU against v1's own example corpus.

Digest: [friend-repos/hpwit-new-parser.md](../friend-repos/hpwit-new-parser.md). - **Code-quality reality (for the redesign).** Header-only, ~18K lines across 11 headers, **pervasive global state** (`string signature; Token __t;` and dozens of file-scope compiler counters), no IR, no unit tests, a 4,100-line `Parser` and a 5,824-line `NodeToken`. It works and it's fast, but it is **not** a base to extend in place β€” it's the reference to learn from and rewrite against our architecture (exactly the *Industry standards, our own code* method we used for LED drivers). - **Recommendation: build our own native engine, Xtensa-first, behind an IR seam β€” start small, start beautiful, no dead-ends.** Take the ESPLiveScript *approach* (native machine-code execution, near-100% speed β€” the standout, never-done-before-in-this-space when bound to a module system) and add the one thing our multi-target goal needs that a single-ISA engine doesn't: put an **IR seam** between a platform-independent front-end (tokenizerβ†’parserβ†’AST) and the code generator. **Ship one backend first β€” Xtensa (classic ESP32 + S3)** β€” exactly where ESPLiveScript already proves native speed; that's the small, beautiful, blazingly-fast first deliverable. The IR seam is the **no-dead-end guarantee**: adding RISC-V (P4), ARM (Teensy), or x86/ARM64 (desktop) later is "write another backend behind the same IR," never "go back to the drawing board." ESPLiveScript's real dead-end isn't *Xtensa-first* β€” it's *Xtensa-welded-in, no IR*; we start at the same fast place but with the seam it lacks. **WASM/WAMR is the named fallback, per target**: a target without a native backend yet can run the portable path through the same IR, so we're never blocked β€” but the *flagship* experience is native. (Detail + why-this-over-WASM-wholesale in Β§ Recommendation.) - **Safety the same way β€” climb the tiers, don't pay upfront.** A user-facing script editor means a bad script must degrade, not brick. Start with the **cheap** safety (array **bounds-checking** = a compare-branch per indexed access, low single-digit %, and removable in a trusted/fast mode; **watchdog / instruction budget** to kill a runaway loop = near-free, the task WDT already does most of it) β€” these catch the common bad-script cases at low cost (the kind the `fix-warnings` null-deref was). The **expensive** tier β€” a true memory sandbox where a script *cannot* touch memory outside its arena β€” is exactly what WASM gives for free and native can't cheaply; leave it as a tier we *can* climb via the IRβ†’WASM fallback if field experience demands it, not a wall we hit.

These are *not* com ## Refreshing -To add a new month (or a new friend repo), run the digest prompt below. When a thread meaningfully shifts, update this index's "cross-repo trends". - -### Digest prompt (reusable) - -> **Friend-repo monthly digest.** For the repo `` (local clone at ``, or via `gh api repos//`), summarise what landed on its **main/default branch** during ``. -> -> 1. Read the merged commits on the default branch with author-date in that calendar month (`git log --first-parent --since/--until` on the local clone, or the GitHub API). Use `--first-parent` so it's the merged-feature view, not every squashed sub-commit. The default branch isn't always `main`/`master` β€” check (`git remote show origin`); e.g. WLED-MM's is `mdev`. -> 1b. **Also investigate the issues over that month.** The REST `gh api repos///issues` endpoint returns **pull requests too** β€” filter them out (`--jq '.[] | select(.pull_request == null)'`) or use the GitHub **search** API, which already excludes them: `search/issues?q=repo:/+is:issue+created:` (and the same with `closed:`). Only real issues, not PRs. The commit log shows what shipped; the issues show what users *hit* and what the maintainers are prioritising β€” the two together are the real activity picture. Skim: notable bugs opened (recurring pain points, hardware quirks), fixes closed that map to a commit, and any heavily-discussed feature request or design thread. Fold the user-facing ones into the summary below (a widely-reported bug that got fixed, a feature the community is pushing for); an issue with no user-facing outcome yet is still worth a one-line "watching:" note if it signals a direction. Don't list every issue β€” surface the few that matter, the same bar as the commit summary. -> 2. **Split a month at any release boundary β€” but only if the release was cut from the branch you're summarising.** If a *versioned* release was published mid-month (check `git for-each-ref refs/tags` / the GitHub releases API; ignore rolling tags like `nightly` and prereleases), AND the tag is an ancestor of the digest branch (`git merge-base --is-ancestor `), split that month at the release date into `## (up to v)` / `## (post-v)`. If the tag is NOT an ancestor (the project cuts releases from a separate release branch β€” e.g. upstream WLED tags off `0_15`/release branches, not `main`), do NOT split: keep the month whole and just note which release shipped that month as context, since the trunk you're summarising feeds future releases rather than being the release line. Whole months with no in-branch release stay one section. -> 3. Write an **end-user-readable** summary: what changed that a *user of the library* would notice or care about β€” new features, new hardware/platform support, notable fixes, breaking changes. Skip internal refactors, CI, test-only, and dependency bumps unless they affect users. -> 4. Format as **short bullet points**, each one line, plainest language, minimal jargon. Group only if there's a natural split (e.g. "New" / "Fixed"); otherwise a flat list. -> 5. Add it as a `## ` section to `docs/history/.md`, newest month on top. Don't editorialise or compare to projectMM β€” just report what they shipped. -> 6. State the commit range / count **and the issue query** summarised so the digest is auditable. -> -> When backfilling several months (e.g. since the last release), run this once per month for a consistent timeline, then optionally add a `## Since v β€” overview` intro at the top with 3–5 bullets naming the multi-month threads the per-month slices can't show on their own. +Adding a month or a new friend repo is the [friend-repos](../friend-repos/README.md) workflow, and its prompt lives there.

The values were saved correctly all along, and thrown away on load. Also reports the P4's Ethernet data pins in the pin map, and re-measures the WiFi co-processor's HTTP cost. Performance: no tick-path change; the new load pass runs once, during setup. Core - Scheduler gains a phase 5: after every module has prepared, saved VALUES are re-applied once. Boot order is defineControls, load, applyState, and a MoonLive script's declared controls exist only after the script COMPILES, which is prepare()'s work. So at load time `cols`/`rows` were in no control list at all, overlayControls skipped them, and prepare() then seeded them from the script's own defaults. applyNode already had a two-pass overlay for a schema depending on a control VALUE (ParallelLedDriver's `peripheral`); this covers a schema depending on prepare's WORK, which no rebuildControls() can produce. - FilesystemModule::reapplyValues re-reads and overlays values only, no tree reconciliation: the shape was settled by the load pass. Once, at boot: after that the live values are the truth and re-reading would undo the edit that triggered any later prepare. It re-reads rather than holding every node's JSON until prepare, which would cost memory on every module for a case that is three (the effect, layout and modifier bindings, and a future driver script). - NetworkModule reports the P4's six RMII data pins through fixedPins(), the same path the S31's twelve RGMII pads use. Verified on MM-P4: Network owns all ten of its Ethernet GPIOs, against four before. platform::ethRgmiiPads is renamed ethFixedPads, since it now holds RMII pins too and the old name was a lie. Tests - a control that only exists after prepare() keeps its saved value (fails without the phase, 16 vs 42). - the pin map lists the pins a module holds without a control naming them, frees them when it stops, and states a capacity the module must respect. Docs - performance.md: the P4's WiFi co-processor costs ~4x per HTTP request and ~2x throughput against the same board on Ethernet, measured on both images over the same cable. No scenario captures this, which is what this page is for. - backlog: the co-processor penalty re-measured on v6.1-rc1 (4x/2x, against 33-60x/17x when written, and the alternating 0.4/0.8 s pattern gone); the classic MDC/MDIO gap marked fixed; the scripted-control entry deleted rather than deferred. Reviews - πŸ‡ CodeRabbit, 13 findings, each verified against current code. Fixed: the classic MDC/MDIO entry still claiming -1, two comments describing the control approach that fixedPins() replaced, a self-contradicting release-boundary note, and unbounded issue queries in the digest this branch added. Skipped with reason: a prose sweep over the friend-repo digests, which check_prose exempts because they quote other projects' own summaries and rewriting them falsifies the record; two "typos" that are quoted upstream text; and retro-fitting audit queries onto eight historical digests, which would fabricate an audit trail. The one finding with real substance was that fixedPins() had no test at all.

NOTE: a board with -1 already persisted keeps it until those controls are set once or NVS is erased. **The fix is the RGMII one, extended.** Being fixed in silicon does not make `gpioCapability`'s reserved list the right home: reserved means "routing I/O here corrupts the device" (flash, PSRAM, USB), which is unconditional, while an EMAC pad is only held while that interface runs. With `ethType = None` the init returns false and every one of those GPIOs is free for LEDs, so a static reserved list would permanently forbid pins a WiFi-only board can use. What makes a control the right shape is not that the pin is configurable (it is not) but that the claim is CONDITIONAL: published when the interface is selected, released when it is not, which is exactly what the pin map reads. diff --git a/docs/backlog/backlog-light.md b/docs/backlog/backlog-light.md index 99820fd3..c462808c 100644 --- a/docs/backlog/backlog-light.md +++ b/docs/backlog/backlog-light.md @@ -353,4 +353,3 @@ The LED-driver increments **shipped**: increment 1 (RMT/WS2812B single-strand on **What it costs when it comes:** a small preallocated record queue the built-in writes into, drained from a housekeeping path through the existing platform output seam.

Every trail in the system now fades at the rate the effect asked for rather than at whatever speed the hardware renders, so a tail is the same length on a 470 fps board and a 140,000 fps desktop. Performance: desktop 1,167 KB (+1), esp32 1,715 KB (+0), esp32s3-n16r8 1,756 KB (+2). metal.mle 59.6 ms/frame on shiffy's 80x48 (12,288 host calls per frame, 3 square roots per pixel); plasma.mle 16.0 ms as the reference. Core: - '/' and '%' are operators, at multiplication's precedence. Both lower to the host call `mod` already used, so the operator costs nothing the capability did not: no ISA here has a divide. The parser resolves them by NAME through the builtin table, so core stays domain-neutral and a domain registering neither simply has no operator. - Layer::fadeToBlackBy takes a RATE per reference frame; the Layer scales it by elapsed time and carries the sub-unit remainder. The clock advances on every frame, not only on frames that fade: leaving it frozen let a gap discharge as one full wipe, snapping a trail to black on resume. Layer::prepare resets it, the guarantee LissajousEffect used to give for its own trail, now given once for every effect. - Classic ESP32 RMII pins declared (TX_EN 21, TXD0 19, TXD1 22, CRS_DV 27, RXD0 25, RXD1 26), from IDF's own RMII Data Plane GPIO table. All ten Ethernet pins now appear in the pin map; verified on MM-Olimex at 100 Mbit. Light domain: - Five builtins: smoothstep, uvX, uvY, smin, fade. Each folds several host calls into one on the per-pixel path, which is the bar now that '/' covers the general case. uv computes one axis per call rather than discarding half of a two-axis result, and stays 32-bit so a large width saturates instead of wrapping past its own guard. - signedArg() is one helper rather than six copies: a script's arithmetic is unsigned, and a builtin that forgets to re-center renders INVERTED rather than failing. - Three effects hand-rolled the elapsed-to-amount conversion and had drifted into two versions (one carried the fraction, two floored to 1 and so over-faded at high rates). All three deleted; the Layer owns it. - RandomEffect spawns per second, StarField's fade left the step gate that throttled it twice, SphereMove clears with draw::fill. fadeToBlackBy(255) no longer means CLEAR: a second meaning at the top of six user-facing sliders was a discontinuity in kind, not degree. - BlurzEffect is NOT migrated and stays framerate-dependent at 3.57. Its per-frame draw::blur is a COMPOUNDING spatial operation, so the carry pattern does not transfer; fixing it needs draw::blur itself to become time-aware. Recorded in the test with its reason. Scripts/MoonDeck: - moonlive/effects/metal.mle: three blobs of liquid metal melting together. The blend control at 0 is three overlapping circles; raised, one surface. Tests: - Framerate bands recorded per effect with reasons rather than widened for all 51. Random and StarField sit outside the lit-pixel metric while their physics matches within 0.5% across 60/240/1200 fps. - Four goldens re-blessed (Fireworks, Lissajous, StarField, BouncingBalls). SphereMove's did NOT move, which is the check that draw::fill reproduces what the sentinel did. - A test that could not distinguish fixed from broken was removed rather than kept: a control check showed it passed with the bug reintroduced. Docs/CI: - The tick-rate rule extended to modifiers and to anything on the tick path, plus where the machinery lives and the two traps found by hitting them. - coding-standards gains the practical form: the carry pattern, why flooring to 1 is the bug, and checking whether something upstream already scales. - Roadmap item 9 (division) marked shipped; 9b added for the ScratchBuffer pool handle that particles need. Reviews: - πŸ‘Ύ Reviewer over the staged diff, 10 findings. - Fade clock frozen on non-fading frames -> fixed (a 5 s gap became a full wipe: scale 2048, rate 60 became amt 480 clamped to 255). - Layer::prepare missing the clock reset -> fixed, orphaned comment removed. - fadeToBlackBy(255) sentinel -> removed entirely, SphereMove uses fill. - uvX/uvY double divides + defeated narrowing guard -> both fixed. - signedArg duplicated six times -> extracted. - Two tests not earning their place -> one deleted, one now asserts the overflow case its description promised. - div lacking the unsigned warning its siblings carry -> accepted, noted. - Framerate bands without a backlog entry for Blurz -> accepted; recorded in the test rather than filed, since the fix is named there. - Dead code after the deletions -> removed. - releaseIfEmpty checking the new sink -> verified correct, no change.

Animation speed mus **A faster device renders the same motion more smoothly, not more motion.** The tempting fix β€” quantise to a fixed 60 Hz and skip the frames in between β€” is wrong here, because it discards exactly the smoothness the extra frames were rendered for. Instead scale the work by the fraction of a reference frame that actually elapsed, so a device rendering ten times as fast takes ten steps a tenth the size: the same trajectory at ten times the resolution. `particles::FrameTime` is the shared implementation (8.8 fixed point, 256 = one reference frame, whose rate is the constructor's `referenceHz` β€” 60 by default). It carries the undivided numerator and divides late, for the same reason `BeatPhase` does: one unit is a fraction of a millisecond, so a remainder held in whole milliseconds cannot represent it and the truncated time β€” which differs by render rate β€” becomes a framerate dependency of its own. -The check is mechanical: **run the effect at two very different framerates over the same span of simulated time and compare.** If the result differs, something is counting frames. +The check is mechanical: **run the effect at two very different framerates over the same span of simulated time and compare.** If the result differs, something is counting frames. `unit_Effects_framerate.cpp` runs exactly that sweep over every registered effect at 60 and 1200 fps. + +**It applies to modifiers too, and to anything else on the tick path.** A modifier that scrolls, rotates or animates its fold is state advanced per call, so the same rule holds: a scroll driven by a per-tick increment moves at the render rate.

Three effects used to carry that conversion themselves and had already drifted into two versions of it (one carried the fraction, two floored to 1 and so applied many times the intended decay at high rates), which is the duplication the one-home rule exists to prevent. `fadeToBlackBy(255)` is the one exception and means CLEAR THIS FRAME: an effect that redraws every pixel wipes first, and scaling that wipe would leave the last frame showing through. + +Two traps worth naming, both found by hitting them. A quantity that is already gated by wallclock must not ALSO be scaled: StarField requested its fade only on stepping frames, and the Layer then scaled each request again, throttling it twice. And a COMPOUNDING spatial operation is not a rate: `draw::blur` applied twice at half strength is not one blur at full strength, so the carry pattern that fixes a fade does not transfer to it (BlurzEffect is the open case). **An effect renders a pattern; it does not transform geometry.** When migrating or adding an effect, strip out anything that is really a *modifier* β€” mirroring, tiling, rotation, scrolling/offset, a kaleidoscope fold, masking, any remap of *where* pixels land β€” and add it as a separate [modifier](#modifiers) instead. WLED (and other sources we port from) routinely fold these into the effect's own loop (a "mirror" checkbox, a "2D" rotation, a built-in pinwheel), because WLED has no modifier concept; we do. Keeping them out of the effect is what lets any effect compose with any modifier (the same RotateModifier rotates Fire, Noise, or a network-received frame) instead of every effect re-implementing its own half-baked mirror. The test: an effect's `tick()` should only *write colors into the logical buffer for its own coordinates*; if it's reading or rewriting positions to move/fold/duplicate the image, that behaviour belongs in a modifier.

With `ethType = None` the init returns false and every one of those GPIOs is free for LEDs, so a static reserved list would permanently forbid pins a WiFi-only board can use.

A ScratchBuffer handle: `pool()` and friends, *the particle blocker* + +**Particles cannot be a script feature without this, and it is the reason the shader step shipped +first.** A `particles::Pool` is eight parallel arrays plus a count (`particles.h:132`).

Even a bigger arena is the wrong answer: `sizeof(MoonLive)` +is held BY VALUE in every scripted module and probed on the main task's stack by `registerType`, +which is what boot-looped the P4 at 1440 bytes (see #3). Particle state must live OUTSIDE the +arena. + +`ScratchBuffer` (`src/core/ScratchBuffer.h`) is already exactly the primitive: one +`platform::alloc`, PSRAM-backed where the target has it, tied to its owning module so it is freed +on disable and counted into that module's `dynamicBytes`. `ParticlesEffect` composes six of them +into a Pool in `prepare()` (`ParticlesEffect.h:46-49, :137`), which is the shape a script wants +too. + +What is missing is the HANDLE: a script has no type but `uint8_t`/`uint16_t`, so it cannot name a +buffer. The shape that fits the existing vocabulary is an arena-resident handle the binding owns, +with the script addressing slots by index: + + pool(200) // in prepare/defineControls: size the pool, once + emit(x, y, vx, vy, ttl) // returns a slot, or the count when full + step(); gravity(g); bounce() // the frame order particles.h documents + +Every one of those is a Call the binding services against a `ScratchBuffer` it holds, so the arena +carries a handle rather than the data, and the 64-byte ceiling stops being the limit on particle +count. Note this is the same "handle route" #3 already argues for, stated concretely: **widen the +arena for scripts that genuinely hold their own state, not as a substitute for this.** + +Two things to settle when it is built: who owns the frame order (the script calling +step/bounce/age in sequence is honest but is five more calls per frame, and `particles.h` warns +the order is the caller's to get right), and what a second script asking for a pool gets, since +`setDrawCanvas` already had to become a per-thread table for exactly this reason. ### 10.

Free functions in the same `.cpp` count; member methods on the owning class are stronger; virtual methods on a base class are strongest. The wrong shape is the same `switch (type)` repeated in every consumer β€” adding a variant means hunting across N files for switches to extend, and the compiler can't tell you when one gets missed. diff --git a/docs/friend-repos/Funkelfetisch-projectMM.md b/docs/friend-repos/Funkelfetisch-projectMM.md index 87d9cf46..1c85de05 100644 --- a/docs/friend-repos/Funkelfetisch-projectMM.md +++ b/docs/friend-repos/Funkelfetisch-projectMM.md @@ -6,7 +6,7 @@ This is a **fork of this project** building a commercial product on it: **HELIO* **Branch note: the work is not on the default branch.** `main` tracks our upstream and has not moved since 2026-07-09; every change lives in named branches, so each month below carries a **Branches** line for what moved on them.

Four example effects ship with it. Separately, a filesystem scan that ran every second on the render thread now runs once a minute, which removed a visible stutter on every device. Performance: desktop 1,185 KB (+18), esp32 1,715 KB (+0), esp32s3-n16r8 1,759 KB (+3). On shiffy's 80x48: fountain.mle 1,093 us against metal.mle's 59,600 us, the per-frame cost model against the per-pixel one. The filesystem fix moved frame deltas from 83/78/80/79/82/66/72 to 83/85/85/83/84/87/85. Core: - FileManagerModule::tick1s called platform::filesystemUsed() every second, which is esp_littlefs_info walking every block of the partition (~80 ms on an S3), INLINE on the render thread, to feed one progress bar. Throttled to once a minute. Pre-existing on main; particles are what made it visible, because a particle integrates a stall into its trajectory (one frame after an 80 ms gap moves every particle 6.7x its usual distance) where a shader just redraws from the clock and skips a frame invisibly. Light domain: - MoonLiveParticles holds six ScratchBuffers, a Pool and a FrameTime, owned by the effect binding. Particle state lives OUTSIDE the script arena: a Pool is eight parallel arrays, and at 64 bytes a script could hold about five particles. Widening the arena was the wrong fix, since sizeof(MoonLive) is probed on the main task's stack by registerType. - Nine builtins: pool, emit, gravity, drag, step, age, render, bounce, collide. pool(n) is reachable ONLY from defineControls(): called from tick() it reports the live count and allocates nothing, which is what keeps a malloc off the render path. The frame scale rides on the pool handle, so framerate independence is the system's property rather than the author's. - collide was rejected in the plan as an O(n^2) foot-gun and re-admitted on measurement: 3.2 us at 48 particles against 0.1 us without, 53.6 us at 200. The quadratic is real; at ball-pit sizes the absolute cost is not. The numbers are at the call site so an author knows what a big pool would cost. - MoonLiveScript::releaseReporting: all three scripted bindings now hand back the bytes they reported when disabled. Only the effect did, which was an asymmetry this change introduced by fixing one of three paths. - sync() reports a DELTA rather than assigning the total: a binding may also own ScratchBuffers, and MoonModule states "don't mix addDynamicBytes with setDynamicBytes". Scripts/MoonDeck: - fountain, comet-trail, rain, ballpit. Between them they show that emit() takes a position and an angle the script computes per frame: a fixed nozzle, a moving emitter shedding a trail, emission scattered along an axis, and balls that pile up. Throw and pull scale with grid height, so a plume fills a 16x16 and a 128x96 alike. - check_taglines.py: README, docs/index.md and CLAUDE.md had drifted into four orderings of the same six platforms, one of which also demoted five of the six to secondary. They are all targets. An include cannot fix this because GitHub renders README.md itself, so the one home is enforced by a gate. Tests: - 12 cases for the pool: sizing, no-default-pool, no-allocation-on-tick, live resize, release, absent handle, a spark that comes back down, a full pool that stops rather than overwriting, slots that recycle, two effects with separate pools, a moving emit seed, and colliding balls that pile higher. - Two tests were removed rather than shipped: each passed with its own bug reintroduced, so neither could tell fixed from broken. Docs/CI: - Every entity in README's Credits now also appears on the doc page covering their part. FPP appeared nowhere in the repo at all; FastLED was absent from the primitives page that describes exactly what it is credited for. - Three misattributions corrected: the WLED Particle System was credited to @Brandon502/WildCats08, but git shows Damian Schneider (@DedeHai) wrote it. He is added to Credits and to the kernel and MoonLive pages. - Roadmap item 9b deleted (shipped) and rewritten with what landed, including the finding that structs were NOT needed: every pool operation is whole-pool or takes scalars, so a script never names a particle field. - Backlogged: capping the particle frame scale.

A script can write 65535 * 65535, which as int32_t is -131071, so a coordinate far off the right of the grid clamped to the LEFT edge after overflowing a signed multiply. 64-bit throughout now, with a regression test that fails when the read is put back to int32_t. - πŸ‘Ύ Reviewer, 4 findings, all fixed: the release-reporting asymmetry above; a duplicated draft comment; ballpit gating emission on a FRAME counter (10/s at 60 fps against 200/s at 1200, breaking the rule this branch documented) now clock-driven at 20/s on any device; and .mle headers over the two-line rule, trimmed on all four. - Cleared on inspection: releaseIfEmpty covers both new sinks, nextEmitSeed's atomic emits no lock guard, dims.x - 1 cannot underflow (the Layer gates on hasGrid), and the release ordering is correct.

Docs/CI: - architecture.md still said `fadeToBlackBy(255)` means CLEAR THIS FRAME. That sentinel was deleted earlier on this branch, so the page licensed exactly the bug the branch removed: someone writing the next clearing effect would have followed it, got a time-scaled fade, and seen the previous frame bleed through. Now states the rule the code states. - The MoonLive roadmap said "seven builtins" and listed `bounce` and `collide` under "not exposed, each with a reason". Nine shipped, and `ballpit.mle` in the same commit calls both. Corrected, with collide's measured N-body numbers carried over. - power-functions.md's `draw::fade` caller list named SphereMove (migrated off it here) and omitted Fireworks. Verified against the call sites: 13 either way, two names wrong. - StarFieldEffect's `blur` control was still described as a per-frame amount; it is a rate per reference frame. - platform_config.h (desktop) carried two paraphrases of the same "a host has no EMAC" comment. - performance.md gains this branch's snapshot: the two cost models side by side (metal.mle 59,600 us against fountain.mle's 1,093 us on the same 80x48, 54x), what makes the shader expensive (polarR wraps a real square root, ~3.5 us per pixel, called three times), collide's non-linear cost, and the frame deltas before and after the filesystem fix. - lessons.md gains three, each one that cost something to learn: a stateful effect is a jitter meter and a stateless one hides the same fault; standardising a duplicated sentence means deciding which version is TRUE first, since the most formal-looking one here was simply wrong; and a test that passes with its own bug reintroduced is worse than no test, which three tests on this branch each did before a control check caught them. Reviews: - πŸ‘Ύ Reviewer over the whole branch diff (88 files, 4 commits). Verdict merge-ready: "net-subtractive in the places that matter". Three findings and two nits, all documentation contradicting shipped code, all fixed above. Cleared on inspection: core stays domain-neutral (zero particles:: references outside the light domain), the '/' operator seam resolves by name through the builtin table rather than hard-coding a function, a non-particle effect pays one FrameTime::advance per Layer per frame, and the five example scripts are each a distinct shape rather than variations.

Giving 255 a second meaning put a discontinuity in kind at the top of six user-facing fade sliders. Two traps worth naming, both found by hitting them. A quantity that is already gated by wallclock must not ALSO be scaled: StarField requested its fade only on stepping frames, and the Layer then scaled each request again, throttling it twice. And a COMPOUNDING spatial operation is not a rate: `draw::blur` applied twice at half strength is not one blur at full strength, so the carry pattern that fixes a fade does not transfer to it (BlurzEffect is the open case). diff --git a/docs/backlog/moonlive-language-roadmap.md b/docs/backlog/moonlive-language-roadmap.md index 04b60cb5..b425451c 100644 --- a/docs/backlog/moonlive-language-roadmap.md +++ b/docs/backlog/moonlive-language-roadmap.md @@ -309,7 +309,11 @@ would have held about five particles.
