ESP32 s3 GPIO info
RTC GPIO chân này có thể làm gì nhỉ
RTC GPIO là những chân đặc biệt có thể hoạt động ngay cả khi chip đang ở chế độ deep sleep.
1. Đánh thức từ chế độ ngủ (Wakeup from Deep Sleep)
Bạn có thể cấu hình để ESP32-S3 tự động đánh thức khi có tín hiệu từ bên ngoài (ví dụ: nút nhấn, cảm biến...)
2. Giữ trạng thái chân khi ngủ (GPIO Hold)
Khi ESP32-S3 vào chế độ deep sleep, các chân GPIO thường bị reset về trạng thái mặc định.
Với RTC GPIO, bạn có thể giữ nguyên trạng thái HIGH hoặc LOW trong suốt thời gian ngủ.
