Touch INterrupt Problem on ARDUINO IDE#5493
Description
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")} }
