Replace USE_PIN_TFT bit-bang software SPI (~8-10 fps) with LovyanGFX
hardware FSPI (SPI2_HOST, 40 MHz, DMA) matching Meshtastic's architecture.
Files:
- variants/rak_tap_v2/LGFXDisplay.{h,cpp}: new DisplayDriver via LovyanGFX
- variants/rak_tap_v2/target.{h,cpp}: SPI.begin() in radio_init() for FSPI
- platformio.ini: DISPLAY_CLASS=LGFXDisplay, LGFX_INVERT_COLOR, LovyanGFX dep
- src/ui-touch/UITask.cpp: RAK path includes LGFXDisplay + 320x40 LVGL buffer
- NOTICE: LovyanGFX dependency

// RAK WisMesh Tap V2 — LovyanGFX-based ST7789 display driver.
|
|
//
|
|
// Replaces the USE_PIN_TFT (bit-bang software SPI) path with LovyanGFX
|
|
// hardware SPI on SPI2_HOST (FSPI). The Arduino framework's default SPI
|
|
// already initialised FSPI on the TFT pins (13/11/10 from pins_arduino.h);
|
|
// LovyanGFX with bus_shared=true reuses that existing bus.
|
|
//
|
|
// This is architecturally identical to what Meshtastic's rak_wismesh_tap_v2
|
|
// variant does — same SPI host, same pins, same library.
