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()
{

}
