M5Stack PaperDIY Complete Kit · intermediaire · Configurez le cycle de veille profonde pour maximiser l'autonomie de la batterie de 140 mAh grâce à la puce M5PM1.
Hardware: PaperDIY Complete Kit, charged battery, current meter (optional). 2. Setup: Use the M5Stack library. Access the M5.Power class to manage the M5PM1 chip. 3. Wiring: The kit is self-contained. Ensure the power switch is ON. 4. Commands: Configure a wake-up source (RTC or GPIO button). Example: M5.Power.setWakeupTime(60) for a 60-second wake-up. Call M5.Power.deepSleep() to enter sleep mode. The M5PM1 chip cuts main power except for the wake-up circuit. 5. Verification: Measure sleep current (must be < 10 µA). Verify wake-up triggers correctly and display resets cleanly. 6. Deep Dive: Create a dashboard that wakes every 5 minutes to fetch sensor data, displays it on the e-paper, then returns to sleep, optimizing battery life.
