Hi Frank,

Any idea on touch function works with C2?

It makes us depressed.

Hi smallfat,

my WaveShare display is broken, so i'm unable to test it.
Please post your debug data, maybe it helps to solve the issue.

Is your Display Ver. 2.1?

Hi Frank,

Refer to touch screen no function of WaveShare 7" (C) ver 2.1
Debug file attached

After above debug capture, I disable watchdog and change display zoom to 0.85.
when i use two fingers to touch screen, screen changed to blank (all white color)

Even I unplug and plug USB cable, it cannot be recovered.
