Cannot run calibration on raspberry pi 4

Open hanneslinder opened this issue 4 years ago • 0 comments

When trying to run touch-test.py on my raspberry pi 4 (running raspberry pi OS) I get the following error:

Device found:  /dev/hidraw2
Reading device
error: XDG_RUNTIME_DIR not set in the environment.
A1..A7:  15847 -11532 -2804646 -585 7964 -1169328 65536
Screen dims: X= 800  Y= 480
Traceback (most recent call last):
  File "touch-test.py", line 174, in <module>
    test_calib_screen(deviceFound)
  File "touch-test.py", line 91, in test_calib_screen
    screen = pygame.display.set_mode(ssize, pygame.FULLSCREEN)
pygame.error: Could not initialize EGL

Touchscreen is working nicely with this driver, but I need to calibrate it as something is currently off - touch is only registered on ~ 1/3 of the screen and starts to shift the further I move right. Probably just a calibration thing, but I was unsuccessful to do this without the calibration script so far.

Any input would be really appreciated :)
