ArduinoNRF documentation

All project documentation lives here. Start with the project README for the overview and quick start.

Getting started & status

COMPATIBILITY.md — OS support matrix (Windows / Linux / macOS) and real-board identity audit
VALIDATION.md — what's verified on real hardware, timing, and how to reproduce it
release/RELEASE_NOTES_v0.1.0.md — current release notes
release/RELEASE_NOTES_v0.0.1.md — initial release notes
release/README.md · release/PRE_RELEASE_CHECKLIST.md — release flow

uploads/hands_free_upload.md — button-less serial-DFU on the maintenance CDC (the default verified path is the ProMicro clone's promicroserialnosd workflow)
uploads/double_reset_upload.md — manual double-reset bootloader entry
uploads/swd_only_upload.md — flashing via an SWD probe
platform/UPLOAD_BEHAVIOR.md — upload policy and behavior
platform/USB_1200_TOUCH_V1_FIX.md — the firmware fixes that make hands-free upload work
bootloaders/README.md — bootloader families

platform/ARDUINO_IDE2_USB_GDBSTUB.md — single-cable USB-CDC GDB-stub debugging in Arduino IDE 2
examples/vscode/README.md — sample launch.json / tasks.json for VS Code + cortex-debug

platform/PWM_MULTI_MODULE.md — 4-module / 16-channel PWM facade, per-pin frequency, polarity, complementary pairs
platform/RTC_DRIVER.md — low-level driver for RTC0/1/2 (compare + overflow IRQs)
cores/arduino/NrfPower.h — power management: System ON sleep (WFI/WFE), low-power / constant-latency sub-modes, DCDC, RAM retention, SystemOFF + GPIO / NFC / USB wake sources
cores/arduino/NrfNfcTag.h — NFC-A Type 2 tag emulation (NDEF URI / text), field detect IRQ, read count
cores/arduino/NrfPeripherals.h — NrfRng (TRNG), NrfWdt (watchdog), NrfTemp (die temp), NrfQdec (rotary encoder), NrfTimer (TIMER0–4), NrfNvmc (flash erase/write), NrfPpi (peripheral routing), NrfEgu (software events + SWI on 6 channels), NrfComp (analog comparator), NrfMwu (memory watch unit), NrfGpioteOut (output channels for PPI use)
cores/arduino/NrfMediaPeripherals.h — NrfQspi (external NOR flash), NrfPdm (MEMS mic), NrfI2s (digital audio). API complete; not verified on the reference ProMicro (no external flash/mic/codec wired) — boards with that hardware need their own verification pass.

platform/NIMBLE_INTEGRATION_PLAN.md — libraries/NimBLE/ is not done yet: parts of the Mynewt porting/NPL layer are vendored, but the real connection/GATT stack is not in-tree and begin() still returns NIMBLE_NOT_VENDORED.
platform/CC310_INTEGRATION_PLAN.md — libraries/CC310/ is still a true skeleton until Nordic's libcc_310.a is provided; the public API exists, but operations return CC_NOT_VENDORED.
platform/ZIGBEE_INTEGRATION_PLAN.md — libraries/Zigbee/ is still a true skeleton; the Zboss + nrf-802154 runtime is not vendored and begin() returns ZIGBEE_NOT_VENDORED.
platform/THREAD_INTEGRATION_PLAN.md — libraries/Thread/ is not done yet: OpenThread headers and some glue are present, but the actual OpenThread core + radio path are not vendored and begin() returns THREAD_NOT_VENDORED.
