touchAttachInterrupt fail on ESP32-S3-WROOM

[Plombir18]

Hi guys,

the touch interrupt event never occurs in my code. I am using VS code with PlatformIO and Arduino framework.

Below is my code snippet:

#define STATE_GPIO_TOUCH_BUT1       4       // PIN definition for button 1
int threshold_diff = 1000;
touchAttachInterrupt(STATE_GPIO_TOUCH_BUT1, gotTouchBut1, touchRead(STATE_GPIO_TOUCH_BUT1)+threshold_diff);

void gotTouchBut1(){
    Serial.print("Button1 ");
    Serial.println(millis());
}

The thresholds are 45,000 for the untouched state and 55,000 for the touched state. Yet the gotTouchBut1() function is never called. Did I miss something?

If I use the same code on an ESP32-S2, it works without problems and enters the interrupt area as desired.

Thanks in advance
