DFRobot FIREBEETLE BOARD-ESP32 - Page 48

Welcome to DFRobot: www.DFRobot.com.cn 48 / 49
esp_deep_sleep_enable_ext0_wakeup is an bottom level setting function. Please do not worry
about its principle and underlying settings related, you just need to know how to use it.
Allocable interruption pin and corresponding pins in the FireBeetle Board-ESP32 shown as below.

Caution: Please only use GPIO_NUM_X to pass a parameter of pin when allocate the interrupt pin
to awake. Due to the underlying function called cannot pass Dx directly in Arduino ino file.
