[Question]DMG80480C070_03WTC touch not working anymore

Edje11

Hi,

I had a fine working DMG80480C070_03WTC diplay, however during developing the touch screen stoped working.
I copied the cfg again to the screen with the touch settings, however this doesn't help.
Download the factory demo program again, but still no touch screen working.
Pressed 20x witin 4 seconds, but no recalibrate screen.
Send over serial AA 5A A5 CC 33 C3 3C to calibrate te screen, but no calibrate screen.

Any tips how to reset the display or how to check if the touchscreen hardware is ok.?

Hello, this screen has two development modes, one is DGUS2 mode and the other is instruction set mode.
If you are in the first mode, you need to start the calibration in the CFG file, then put the CFG file into the DWIN_SET folder, download it to the screen, enter the blue interface, unplug the power, and continuously tap the four corners of the screen, then calibrate After finishing, use TA mode again.
