Strangely I have managed to get the ILI9341 working as a monitor by some tweaking of overlays on the Le Potato but whatever I do I can't run the Simple Test Example without generating an error. I include some of the different combinations of overlay I tried and the overlays themselves.

Ili9341 SimpleTest Example configured for Le Potato

spi = Board.SPI()
tft_cs = board.P24
tft_dc = board.P29

display_bus = displayio.FourWire(
spi, command=tft_dc, chip_select=tft_cs, reset=board.P31
)

No Overlays Enabled # Doesn't work which is as expected - OSError: /dev/spidev0.0 does not exist
