3. Guia de configuració

Follow these steps to prepare your ESP32 development board for programming.

3.1 Instal·lació del controlador

The board uses a CP2102 USB to UART bridge. You may need to install the appropriate drivers for your operating system. These drivers are typically available from the Silicon Labs weblloc.

1. Visit the official Silicon Labs weblloc.
2. Cerca "CP210x USB to UART Bridge VCP Drivers".
3. Download and install the driver package compatible with your operating system (Windows, macOS, Linux).
4. Reinicieu l'ordinador si se us demana.

3.2 Integrated Development Environment (IDE) Setup

The Arduino IDE is a popular choice for programming ESP32 boards. Ensure you have the ESP32 board support package installed.

1. Baixeu i instal·leu l'IDE d'Arduino des de l'Arduino oficial weblloc.
2. Open the Arduino IDE and go to File > Preferències.
3. In the "Additional Boards Manager URLs" field, add the following URL: https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
4. Vés a Tools > Board > Boards Manager...
5. Cerca "ESP32" and install the "esp32 by Espressif Systems" package.
6. After installation, select your board under Tools > Board > ESP32 Arduino. For this board, select "DOIT ESP32 DEVKIT V1" or a similar generic ESP32 Dev Module option.

3.3 Connexió física

Connect the ESP32 board to your computer using a Micro USB cable.

Note on Breadboard Compatibility: This 30-pin ESP32 board is wider than standard breadboards. To use it with a solderless prototype board, you may need to dock two breadboards side-by-side to provide sufficient space for the pins and access to both sides.

4. Instruccions de funcionament

Once your development environment is set up, you can begin programming your ESP32 board.

4.1 Uploading a Sketch (Arduino IDE)

1. Open your sketch in the Arduino IDE.
2. Ensure the correct board (e.g., "DOIT ESP32 DEVKIT V1") and COM port are selected under Eines. The COM port corresponds to the CP2102 USB-UART bridge.
3. Click the "Upload" button (right arrow icon) in the Arduino IDE.
4. The IDE will compile and attempt to upload the sketch. During the upload process, you might see messages like "Connecting..."
5. If the upload fails with a "Failed to connect to ESP32" error, you may need to manually put the board into bootloader mode. Press and hold the BARRETA button on the board, then press the EN (Enable/Reset) button briefly, release EN, i després deixa anar BARRETA. Alternatively, some boards require holding the BARRETA button down throughout the entire upload process.

4.2 Modes de xarxa

The ESP32 supports three primary Wi-Fi modes:

• Mode d'estació (STA): The ESP32 connects to an existing Wi-Fi network (like your home router).
• Mode de punt d'accés (AP): The ESP32 creates its own Wi-Fi network, allowing other devices to connect to it.
• AP+STA Mode: The ESP32 acts as both an Access Point and a Station simultaneously.

These modes are configured within your program code using the ESP32 Wi-Fi library.

5. Manteniment

Proper care will ensure the longevity and reliable operation of your ESP32 development board.

• Emmagatzematge: Guardeu la placa en un entorn sec i antiestàtic quan no la feu servir.
• Neteja: If necessary, gently clean the board with a soft, dry brush or compressed air. Avoid using liquids.
• Manipulació: Handle the board by its edges to avoid touching components, especially the pins, which can be sensitive to static discharge.
• Font d'alimentació: Always use a stable 5V power supply via the Micro USB port or the VIN pin. Avoid over-voltage.

6. Solució De Problemes

Aquí teniu solucions a problemes comuns que podeu trobar:

6.1 "Failed to connect to ESP32: Timed out waiting for packet header"

This error typically indicates that the board is not entering bootloader mode correctly for programming.

• Problema amb el controlador: Ensure the CP2102 drivers are correctly installed and the board is recognized as a COM port in your operating system's device manager.
• Incorrect Port/Board: Verify that the correct COM port and ESP32 board type (e.g., "DOIT ESP32 DEVKIT V1") are selected in the Arduino IDE under Eines.
• Manual Boot Mode: As described in Section 4.1, try manually putting the board into bootloader mode by holding the BARRETA button during the upload process, or by pressing BARRETA, doncs EN, then releasing EN, doncs BARRETA.
• Cable USB: Ensure you are using a data-capable USB cable, not just a charging cable.

6.2 Board Not Recognized by Computer

If your computer does not detect the ESP32 board:

• Comprovació del conductor: Reinstall the CP2102 drivers.
• Port USB: Proveu un port USB diferent a l'ordinador.
• Cable USB: Test with a different Micro USB cable.
• Danys físics: Inspect the Micro USB port on the board for any visible damage.
