BOARD_TOUCH_IRQ in utilities.h

[kc427hk]

Hi all,

The file utilities.h in the example folder, the BOARD_TOUCH_IRQ is set to 7, GPIO7, but when I check the schematic, shouldn't it be GPIO21 ?

Also, anyone know how to put the device in deep sleep, and then wake up by touching the screen? How to do it properly? I have tried putting it in deep sleep, but it would wake up automatically after about 5 seconds.

Here is my code to put ESP32 into sleep:

void GoToSleepNow(void)
{
  // Erase the display.
  tft.fillScreen(TFT_BLACK);

  // LCD off.
  digitalWrite(TFT_BL, LOW);

  // Delay.
  delay(2000);

  // Enable touch sleep.
  touch.sleep();

  // Set wake up source fo the sleep mode. 
  gpio_hold_en((gpio_num_t)BOARD_TOUCH_RST);
  //gpio_deep_sleep_hold_en();
  esp_sleep_enable_ext0_wakeup((gpio_num_t)BOARD_TOUCH_IRQ, 0);
  //esp_sleep_enable_ext0_wakeup((gpio_num_t)BOARD_TOUCH_IRQ, 1);   // 1, keep sleeping and won't wake up anymore
  esp_deep_sleep_start();         
}

thanks

The touch terminal pin is 21, which has been updated

Touch wake-up, touch cannot be set to sleep.
