Hi,

I want to use touch interrupt feature on esp32. So ı opened example code from library: TouchInterrupt.
When ı compile and upload to esp32 ı saw just that texts on serial port screen ;

ESP32 Touch Interrupt Test

I touched T0 and T3 pins but esp32 has never went into interrupt functions. I tried that code multiple computer but result was same.

I use Arduino IDE 1.8.15 version with Nodemcu V1 ESP32 Devkit.

Note that touchRead function works very well. Only problem is about touch interrupt.

Code:

/*
This is an example how to use Touch Intrrerupts
The bigger the threshold, the more sensible is the touch
*/

int threshold = 40;
bool touch1detected = false;
bool touch2detected = false;

void gotTouch1(){
 touch1detected = true;
}

void gotTouch2(){
 touch2detected = true;
}

void setup() {
  Serial.begin(115200);
  delay(1000); // give me time to bring up serial monitor
  Serial.println("ESP32 Touch Interrupt Test");
  touchAttachInterrupt(T0, gotTouch1, threshold);
  touchAttachInterrupt(T3, gotTouch2, threshold);
}

void loop(){
  if(touch1detected){
    touch1detected = false;
    Serial.println("Touch 1 detected");
  }
  if(touch2detected){
    touch2detected = false;
    Serial.println("Touch 2 detected");
  }
}
