Interrupt pin not working w/ ESP32-C3-MINI-1
Posted: Thu Aug 03, 2023 2:40 pm
Hello guys! I am trying to implement code for a EXT0 and/or EXT1 wake-up strategy for the ESP32-C3-MINI-1. I am using the Wokwi simulator to test since I have not yet received the Dev kit. However, I am unable to even get the board to wake-up from EXT0 strategy let alone EXT1. I am not sure what is wrong within the code. Any help is appreciated, thank you! (Also I did try to use the esp_sleep.h library, but that did not change any outcomes)
Code: Select all
#define INTERRUPT_PIN 3
RTC_DATA_ATTR int bootCount = 0;
void setup() {
Serial.begin(115200);
delay(1000);
//pinMode(LED, OUTPUT);
// digitalWrite(LED, LOW);
++bootCount;
Serial.println("Boot number: " + String(bootCount));
print_wakeup_reason();
Serial.println("Starting");
delay(2000);
for(int i=3; i!=0; i--){
Serial.println(i);
delay(1000);
}
Serial.println("Going to sleep now");
esp_deep_sleep_enable_gpio_wakeup(1 << INTERRUPT_PIN, ESP_GPIO_WAKEUP_GPIO_HIGH);
esp_deep_sleep_start();
Serial.println("This will never be printed");
}
void loop() { }
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;
}
}
