Description:

hi，Open the touch function can wake up the device io，how to disable touch pad interrupts?I need a function like detachInterrupt.

Sketch: (leave the backquotes for code formatting)

#include <Arduino.h>

#define PIN_TOUCH1 12
#define PIN_TOUCH2 13
#define PIN_TOUCH3 14
#define PIN_TOUCH4 15

int threshold = 40;

void start_sleep()
{
  //Go to sleep now
  Serial.println("Going to sleep now");
  esp_sleep_enable_touchpad_wakeup();
  esp_deep_sleep_start();
}

void touch1_cb()
{
  Serial.println("touch1_cb");
}

void touch2_cb()
{
  Serial.println("touch2_cb");
}

void touch3_cb()
{
  Serial.println("touch3_cb");
}

void touch4_cb()
{
  Serial.println("touch4_cb");
}


void print_wakeup_reason()
{
  esp_sleep_wakeup_cause_t wakeup_reason;

  wakeup_reason = esp_sleep_get_wakeup_cause();

  switch (wakeup_reason)
  {
  case ESP_SLEEP_WAKEUP_EXT0 :
    Serial.println("Wakeup caused by external signal using RTC_IO");
    break;
  case ESP_SLEEP_WAKEUP_EXT1 :
    Serial.println("Wakeup caused by external signal using RTC_CNTL");
    break;
  case ESP_SLEEP_WAKEUP_TIMER :
    Serial.println("Wakeup caused by timer");
    break;
  case ESP_SLEEP_WAKEUP_TOUCHPAD :
    Serial.println("Wakeup caused by touchpad");
    break;
  case ESP_SLEEP_WAKEUP_ULP :
    Serial.println("Wakeup caused by ULP program");
    break;
  default :
    Serial.printf("Wakeup was not caused by deep sleep: %d\n", wakeup_reason);
    break;
  }
}

void print_wakeup_touchpad() {
  touch_pad_t touchPin;

  touchPin = esp_sleep_get_touchpad_wakeup_status();

  switch (touchPin)
  {
  case 0  : Serial.println("Touch detected on GPIO 4"); break;
  case 1  : Serial.println("Touch detected on GPIO 0"); break;
  case 2  : Serial.println("Touch detected on GPIO 2"); break;
  case 3  : Serial.println("Touch detected on GPIO 15"); break;
  case 4  : Serial.println("Touch detected on GPIO 13"); break;
  case 5  : Serial.println("Touch detected on GPIO 12"); break;
  case 6  : Serial.println("Touch detected on GPIO 14"); break;
  case 7  : Serial.println("Touch detected on GPIO 27"); break;
  case 8  : Serial.println("Touch detected on GPIO 33"); break;
  case 9  : Serial.println("Touch detected on GPIO 32"); break;
  default : Serial.println("Wakeup not by touchpad"); break;
  }
}



void setup()
{
  Serial.begin(115200);
  Serial.println();
  Serial.println("Starting...");

  print_wakeup_reason();
  print_wakeup_touchpad();

  touchAttachInterrupt(PIN_TOUCH1, touch1_cb, threshold);
  touchAttachInterrupt(PIN_TOUCH2, touch2_cb, threshold);
  touchAttachInterrupt(PIN_TOUCH3, touch3_cb, threshold);
  touchAttachInterrupt(PIN_TOUCH4, touch4_cb, threshold);


  // pinMode(PIN_TOUCH1, OUTPUT);
  // pinMode(PIN_TOUCH2, OUTPUT);
  // pinMode(PIN_TOUCH3, OUTPUT);
  // touch_pad_intr_disable();
  // touch_pad_clear_status();
  start_sleep();
}

void loop()
{

}
