Programming

Follow the editor's guide (README.md file) and don't miss importing the previous TEMPLATE file as settings (cf. setup).

In summary:

  1. Connect your ESP-32-Cam to your PC via USB
  2. Only when flashing, connect the GPI0 to the Ground
  3. Install and open the Arduino IDE
  4. Open the Arduino sketch: esp32-cam-webserver.ino (from the uncompressed archive :)
  5. Configure the Arduino compiler
    1. Install the driver for the board esp32
    2. Select the board: AI Thinker ESP32-CAM
    3. Select your USB port
  6. Run the check and compile command

Ready to be used!
