Hi, I'm experiencing this flashing issue on the JLX display, its a newer board that I bought this year.
I'm running Tinypilot on Pi Zero 2 and using Stelian's image, since that image is fom 2021 it does not have the software bug fix that Sean posted in this thread. To make the fix, I edited the .cpp file manually, but Im not sure what to do afterwards. I'm a hardware guy so a little out of my league at this point. Heres what I did so far, am I missing anything ?
My setps so far (still not working):
1) edit/save the /mnt/mmcblk0p2/tinypilot/pypilot/hat/ugfx.cpp file (comment out one line per Sean's fix)
2) python3 setup.py build_ext --force --inplace
3) power cycle the system
More info:
- My JLX board looks differnt than either of Onno's pics.
- I can only get it to show a solid screen if I pull the /CS (pin 12), but the screen wont refresh.
- When I scope the /CS pin, I also dont have a regular signal, similar to what Onno observed.
Help is much appreciated, thanks !!!
