Note that some of the screens have **TWO** versions, **Resistive** and **Capacitive**, so flash the correct firmware (ends in `r` or a `c` respectively).

**RESISTIVE**: After first boot, Run a `Calibration` via the web ui -> Display Setup -> Calibrate

Then on the screen, touch the indicated points.
**RESISTIVE**: The `r` firmware drives resistive touch with a standalone XPT2046 driver (this board's RGB-parallel panel is driven by ArduinoGFX, so touch runs on its own SPI bus) and ships with a working calibration baked in for the panel, so it is usable out of the box. Its calibration is set via the `TOUCH_XPT2046_*` build flags (notably `SWAP_XY` and the raw min/max window) rather than the web UI *Display Setup -> Calibrate* flow — adjust those and recompile to fine-tune. Resistive-touch support for this board was added in [openHASP #1028](https://github.com/HASwitchPlate/openHASP/pull/1028).
