Flashing:
- Download the latest version of CircuitPython for the Raspberry Pi Pico.
- Connect the cart using a USB A to C cable and drop the CircuitPython .uf2 file onto the device.
- Once the CircuitPy device pops up, move the files that correspond to your display from "Circuitpy Files" onto your device. Choose the correct resolution matching the display installed.
- Drop a 152x152 or 200x200 1 or 2 bit BMP onto the device to update the e-ink display image. Choose the correct resolution matching the display installed.
