M5.Power.deepSleep(5000000, true);
}
delay(20);
} After the program starts, the screen shows two sleep operations. Pressing button A enters light sleep for 5 seconds; after wakeup, execution continues from the line following lightSleep() and indicates that wakeup is complete. Pressing button B enters deep sleep for 5 seconds; after the timed wakeup, the ESP32-S3 resets and starts again from setup().
API
The PaperMono sleep and wakeup features use Power_Class from the M5Unified library. For more information, refer to the following documentation:
