G'day Canada,
These are quite a nice display unit.
Try LIST SYSTEM I2C first and see if you get a response at address &H38, this is the touch controller so needs to respond, if not check wiring.
The TOUCH INTERRUPT pin must be working (GP24 in your system), this is a green wire on the unit I have here. If this isn't working you will not get a response from the touch calibration.
Good Luck.
Regards, Lyle.
