I assembled the 2.8" PiTFT screen and followed the software setup instructions here: https://learn.adafruit.com/adafruit-2-2 ... spberry-pi. The display works like a charm, looks really nice :). Sadly however, the touchscreen capability doesn't work at all.
I looked into the FAQ and there was a solution for what appeared to be equivalent to my problem (viewtopic.php?f=50&t=104964), but the posted solution is 5 years old, and my system was already diverging at the first instruction (I could not find any .dtb files, only .dtbo, nor could I extract anything from the "/boot/overlays/pitft28-resistive.dtbo" file.
I do get this output from dmesg, which at least seems to imply to me that I have an equivalent issue:
Code: Select all
[ 4.675025] stmpe-spi spi0.1: unknown chip id: 0x0
[ 4.675077] stmpe-spi: probe of spi0.1 failed with error -22
Thanks in advance,
