Watch 2020 V2 / attachinterrupt and touchsreen

[FXVT]

Bonjour everybody,

I try to call the ToucheEcran subroutine with this interrupt, but it does'nt works.

const byte interruptPin = 38; pinMode(interruptPin, INPUT_PULLUP); attachInterrupt (digitalPinToInterrupt(interruptPin), ToucheEcran, CHANGE); I have understand that the touch screen interrupt is on pin 38. Could you please tel me what is wrong.

The classic command ttgo->getTouch(x,y) works, but I would like to try to get a faster result using attachInterrup.

Merci. FX
