9 years ago Hrm I'm not familiar with that display, but the code as-is makes some assumptions about running on a PiTFT touchscreen. Here's where freqshow.py configures itself to use the PiTFT mouse (exposed on the /dev/input/touchscreen path): https://github.com/adafruit/FreqShow/blob/master/freqshow.py#L75-L76 If you can find where the touchscreen you're using exposes its mouse then try changing that path to point at it. Good luck!
Hello all from a total pi newbie.
I recently purchased an ads7846 touchscreen and after a little while got the display working. Now running well. I tried to expand into freqshow and having trouble when running freqshow.py
I now get error message saying:
File "freqshow.py", line 77, in
pygame.display.init()
pygame.error: Unable to open mouse
Grateful for any advice on this one.
