Unit PoE CAM Program Compilation and Flashing

1. Preparations

• 1. Arduino IDE Installation: Refer to the Arduino IDE Installation Tutorial to complete the IDE installation.
• 2. Board Manager Installation: Refer to the Basic Environment Setup Tutorial to complete the M5Stack board manager installation and select the development board M5PoECAM.

• 3. Dependency Library Installation: Refer to the Library Manager Installation Tutorial to complete the installation of the M5PoECAM driver library.

• 4. Hardware products used:
  • ESP32 Downloader
  • Unit PoE CAM-W v1.1

2. Flashing Tool

Use the adapter board provided with the ESP32 Downloader to connect to the reserved program download interface on the Unit PoE CAM-W v1.1. Follow the steps below to flash the firmware.

3. Port Selection

• Connect the device to the computer via a USB cable, and select the corresponding device port in the Arduino IDE.

4. Program Compilation & Flashing

• Open the example program "web_cam - eth" in the driver library, click the Upload button, and the program will automatically compile and flash.

// for CAMERA_OV2640 ( Unit PoE CAM / Unit PoE CAM-W )
PoECAM.Camera.sensor->set_vflip(PoECAM.Camera.sensor, 0);
PoECAM.Camera.sensor->set_hmirror(PoECAM.Camera.sensor, 0);
PoECAM.Camera.sensor->set_framesize(PoECAM.Camera.sensor, FRAMESIZE_UXGA); //1600x1200
// for CAMERA_OV3660 ( Unit PoE CAM-W v1.1 )
PoECAM.Camera.sensor->set_vflip(PoECAM.Camera.sensor, 0);
PoECAM.Camera.sensor->set_hmirror(PoECAM.Camera.sensor, 1);
PoECAM.Camera.sensor->set_framesize(PoECAM.Camera.sensor, FRAMESIZE_QXGA); //2048x1536

After connecting a serial tool, reset the device or power it on again, then check the device IP. Access the IP via a browser to preview the image in real time.
