# E-Ink F1 Display

## Raspberry Pi Pico W (Arduino)

This project targets the Raspberry Pi Pico W using the Arduino-Pico core
through PlatformIO and the Waveshare 4.2-inch V2 display. The display GPIO
assignments are in `include/config.h`.

1. Copy `src/secrets.h.example` to `src/secrets.h` and set your Wi-Fi SSID and
   password. The actual `src/secrets.h` is ignored by Git.
2. Build with `pio run -e pico_w`.
3. Upload with `pio run -e pico_w -t upload`.
4. Open the serial monitor with `pio device monitor -e pico_w`.

The display uses GPIO 8 (DC), GPIO 9 (CS), GPIO 10 (SCK), GPIO 11 (MOSI),
GPIO 12 (RST), and GPIO 13 (BUSY).
