Here using purple.bmp and the example code from Carter Nelson's excellent displayio guide.
Using the gamma correction fix code from the forum: viewtopic.php?f=65&t=168145&start=60#p825486 fixes the problem
Code: Select all
display.bus.send(0x26, b"\x04")
The change doesn't persist after reset - will this fix have to be called in each CircuitPython script, or is there a way to permanently make this change? I'd like to use this board for teaching coding, and so would like the process streamlined.
