4. Instruccions de funcionament

The ESP32 Development Board is programmed using various Integrated Development Environments (IDEs) and programming languages. The most common methods include the Arduino IDE and the ESP-IDF (Espressif IoT Development Framework).

1. Programació: Write your code in your chosen IDE. The ESP32 supports C/C++ (via Arduino IDE or ESP-IDF) and MicroPython/Lua.
2. Upload Code: Connect the board to your computer via USB. Select the correct board and port in your IDE, then upload your compiled code.
3. Alimentació de la Junta: The board can be powered via the USB port or through the VIN pin (typically 5V). Ensure the power supply is within the specified voltage gamma.
4. Using GPIO Pins: Connect sensors, actuators, and other peripherals to the GPIO pins on the breakout board. Refer to the GPIO Pinout section for specific pin functions.
5. Configuració de la xarxa: Utilize the Wi-Fi and Bluetooth capabilities to connect your projects to networks or other devices. Configure AP, STA, or AP+STA modes as required by your application.

5. Pinout de GPIO

The ESP32 features a rich set of General Purpose Input/Output (GPIO) pins, each capable of various functions. The breakout board provides easy access to these pins.

This table outlines the primary functions of key GPIO pins. Always consult the ESP32 datasheet for comprehensive pin details and alternative functions.

6. Manteniment

To ensure the longevity and optimal performance of your ESP32 Development Board and Breakout Board, observe the following maintenance guidelines:

• Manejar amb cura: Avoid dropping or subjecting the boards to physical shock.
• Descàrrega estàtica: Always handle the boards in a static-safe environment to prevent damage to sensitive electronic components.
• Mantenir sec: Protect the boards from moisture and liquids, which can cause short circuits and corrosion.
• Neteja: Keep the boards free from dust and debris. Use a soft, dry brush or compressed air for cleaning. Avoid using liquids or abrasive materials.
• Emmagatzematge adequat: When not in use, store the boards in their original anti-static packaging or a protective enclosure.

7. Solució De Problemes

If you encounter issues with your ESP32 Development Board, consider the following troubleshooting steps:

• La placa no s'encén: Ensure the USB cable is securely connected and providing power. Try a different USB port or cable.
• Failed Code Upload:
  • Verify that the correct board type and COM port are selected in your IDE.
  • Assegureu-vos que tots els controladors necessaris estiguin instal·lats.
  • Press and hold the 'BOOT' button while pressing and releasing the 'EN' (Reset) button, then release 'BOOT' to enter bootloader mode for uploading.
• Program Not Running Automatically After Power-Up: Some ESP32 boards may require a manual reset after power-up to run the uploaded program. If your program does not start automatically, press the 'EN' (Reset) button. This can sometimes be related to specific ground pin configurations; ensure proper grounding if you are using external power sources or custom circuits.
• Connexions inestables: If using the terminal adapter, ensure wires are securely fastened by tightening the screws. For pin headers, confirm that all pins are fully inserted and making good contact.
• Problemes de connectivitat Wi-Fi/Bluetooth: Check your code for correct network credentials and configuration. Ensure the board is within range of the access point or Bluetooth device.
• GPIO Malfunction: Double-check your wiring against the pinout diagram. Verify that the GPIO pins are configured correctly in your code (input/output, pull-up/down resistors).
