GPIO17 do not turn tpo LOW
Posted: Sun Dec 10, 2023 7:51 pm
Hi,
I am developing a circuit based on ESPC3-13 module. I faced with a problem in deep sleep task. The problem that I faced; GPIO17 never turn to LOW state after I set it to HIGH at deep sleep mode. But if I set GPIO17 LOW at the beginning and do not set state to HIGH, pin goes LOW without any problem at deep sleep. What may cause this problem? Or how can I solve it? Please find the problematic code below;
Thank you.

Code: Select all
#include "driver/gpio.h"
#define uS_TO_S_FACTOR 1000000 /* Conversion factor for micro seconds to seconds */
#define TIME_TO_SLEEP 60 /* Time ESP32 will go to sleep (in seconds) */
#define INTERRUPT_PIN 3
#define SENSOR_POWER 1
void setup() {
Serial.begin(115200);
pinMode(SENSOR_POWER, OUTPUT);
digitalWrite(SENSOR_POWER, HIGH);
delay(3000);
digitalWrite(SENSOR_POWER, LOW);
esp_deep_sleep_enable_gpio_wakeup(1 << INTERRUPT_PIN, ESP_GPIO_WAKEUP_GPIO_LOW);
esp_sleep_enable_timer_wakeup(TIME_TO_SLEEP * uS_TO_S_FACTOR);
esp_deep_sleep_start();
}
void loop() {
//This is not going to be called
