ESP32-S2 and Touch Pad measured values not changing

[Andyk1062]

Hi all

I don't know if I'm being an idiot here, but I've been trying to run the example code for the ESP32-S2 on the Kaluga-1, in particular the touch-pad-read example using the supplied ESP-LyraP-TouchA V1.1 touchpad.

The program runs fine, but the values measured are constant and don't change when buttons are touched. If the program is stopped, a button is touched and the program is restarted (with the button touched) then the value measured is changed, but stays constant even if the button is no longer touched.

The example code is unchanged and the fact that it does run and give values suggests it's running fine, but it's as if the program just remembers the first value it measures and then doesn't update. Am I missing something here?

Thanks, if anyone has any clues

Andy
