Board

ESP32-S3

Device Description

ESP32-S3-WROOM-1 (N16R8)

Hardware Configuration

Use the gpio3 (Touch3) pin as the touch pin.

Version

v2.0.4

IDE Name

Arduino IDE

Operating System

win10

Flash frequency

QIO 120MHz

PSRAM enabled

yes

Upload speed

921600

Description

Examples of deep sleep included timer, external, and touch, which worked very well on esp32. ESP32-S3 had problems with the Touchwakeup example. Even if you don't touch it, it wakes up as soon as you enter the deep sleep. Is there anyone else who has a problem like me?

Other Steps to Reproduce

I tried by modifying the variables below. But they all failed.

Threshold 40
Threshold 1500
T1 ~ T14 ( gpio 1 ~ gpio14)
Disabled all Wakeup_Source except ESP_SLEEP_WAKEUP_TOUCHPAD.

When I used the function below, the program didn't wake up from deep sleep.
esp_sleep_disable_wakeup_source(ESP_SLEEP_WAKEUP_TOUCHPAD);

I have checked existing issues, online documentation and the Troubleshooting Guide

Hello. I needed a touch to wake my esp32-s3 up
I looked at the document and thought as follows. It is assumed that "ESP_PD_OPTION_AUTO" does not work on ESP32-S3.
Therefore, I added the following code and it worked. esp_sleep_pd_config(ESP_PD_DOMAIN_RTC_PERIPH, ESP_PD_OPTION_ON);
I don't know if this code works normally with low-power deep sleep. My cheap power supply shows 0.00A when deep sleep begins. If you are in urgent need of this function like me, try this method before distributing the official version. :)

#define Threshold 1500 /* Greater the value, more the sensitivity */

void callback(){
  //placeholder callback function
}

void setup(){
  Serial.begin(115200);
  pinMode(7, OUTPUT);
  digitalWrite(7, HIGH); 
  delay(1000); //Take some time to open up the Serial Monitor
  
  int ESP_report3 =esp_sleep_pd_config(ESP_PD_DOMAIN_RTC_PERIPH, ESP_PD_OPTION_ON);
  Serial.println(ESP_report3);
  //T4 -> IO4
  touchAttachInterrupt(T4, callback, Threshold);
  int ESP_report = esp_sleep_enable_touchpad_wakeup();
  Serial.println(ESP_report);
  
  Serial.println("Going to sleep now");
  esp_deep_sleep_start();
}

void loop(){
  //This will never be reached
}

Hallo

Have the same problem.
When I read Sim Gallery's article, I believed that it would also solve my problem.
I tested the sketch from SimGallery but the power consumption is still 60mA in deep sleep mode.
So this is not a solution yet. #
