I am facing issues with the touch events on one of the screens.
According to the documentation https://learn.adafruit.com/adafruit-2-8 ... h?view=all, Capacitive Touch should not require calibration.
I have the following numbers in my /etc/pointercal
320 65536 0 -65536 0 15728640 65536
(according to the documentation)
The above numbers does not really help.
Even when I run
sudo TSLIB_TSDEVICE=/dev/input/event2 TSLIB_FBDEVICE=/dev/fb0 ts_calibration
and calibrate the screen manually, only half of the screen touches are working properly, the other half of the screen is completely wrong.
- Could I have received a unit with faulty touch?
- Could I have somehow damaged the Capacitive Touch of the screen?
