2. ESP32/Camera/Camera/CameraWebServer (STA mode)
  1. Edit CameraWebServer.cpp
    1. #define CAMERA_MODEL_M5STACK_WIDE
    2. set ssid, password
  2. Check router settings
  3. Open serial monitor
  4. Compile and Load
    1. check IP address
  5. Open http://XXX.XXX.XXX.XXX
    1. Push [ Start Stream ] : OK
    2. Change Rsolution (Quantity=10, 他 default)
      - QVGA (320x240) : 25.6fps
      - VGA (640x480) : 12.7fps
