Can't get 2.9" eink FeatherWing working with FeatherS2

by virtualwolf on Fri Jul 30, 2021 7:32 am

Hey everyone,

I have the FeatherS2 and the 2.9" greyscale ePaper FeatherWing and am failing miserably at actually getting the display to show anything using the example code. I suspect it's just a case of the pins not being right as the code says that the pins there are for the Feather M4 and may need to be altered for other boards, but unfortunately I don't know enough about all of this to be able work out what they should be.

I've got the FeatherS2 pinout, the Feather M4 pinout, and the closeup of the actual Feather M4 from the product page all up right now, but I can't make heads or tails of how I should be configuring the thing.

Any and all help is greatly appreciated!

Hah so apparently I'm blind and totally missed the pinouts page for the FeatherWing. I've updated the example code as follows and everything works a treat!

Code: Select all | TOGGLE FULL SIZE
epd_cs = board.IO1
epd_dc = board.IO3
