4. Configuració
4.1 Connexió inicial
To begin using your RP2350-Tiny, you will typically connect it to a computer for programming. If you have the RP2350-Tiny-Kit, use the provided FPC cable and USB adapter board. If you have the standalone RP2350-Tiny, you will need to solder it to a carrier board or use an appropriate FPC adapter (not included) to connect via USB.
For initial programming, connect the board to your computer via a USB cable. The board supports drag-and-drop programming via mass storage mode.
4.2 Kit de desenvolupament de programari (SDK)
Waveshare provides a complete SDK and open-source tutorials to facilitate development. The RP2350-Tiny supports multiple programming languages, including Pico C/C++ SDK and MicroPython.
Figure 4.1: Supported programming languages and SDKs.
Refer to the official Waveshare Wiki resources for detailed documentation and examples. Contact Waveshare support for more information on accessing these resources.
5. Instruccions de funcionament
5.1 Encès
Once connected via USB or integrated into a powered circuit, the board will power on. Onboard RGB LEDs indicate the program running status.
5.2 Programming the Board
The RP2350-Tiny supports drag-and-drop programming. When connected to a computer, it typically appears as a mass storage device. You can drag compiled firmware files (e.g., .uf2 files for MicroPython) directly onto this device to flash the board.
5.3 GPIO Usage
The board features 28 multi-function GPIO pins, allowing for flexible development and integration. 20 pins are available via the edge pinout, with others accessible via solder points. Refer to the pinout diagram for specific functions.
Figure 5.1: RP2350-Tiny GPIO Pinout Diagram.
5.4 Low-Power Modes
The RP2350-Tiny supports low-power sleep and dormant modes, which can be utilized in your applications to conserve energy. Consult the RP2350A datasheet and SDK documentation for details on implementing these modes.
6. Manteniment
The RP2350-Tiny Development Board is a robust electronic component. Minimal maintenance is required.
- Neteja: Keep the board clean and free from dust and debris. Use a soft, dry brush or compressed air for cleaning. Avoid liquids.
- Emmagatzematge: Store the board in an anti-static bag when not in use to prevent electrostatic discharge (ESD) damage.
- Manipulació: Handle the board by its edges to avoid touching components, especially the microcontroller chip.
- Actualitzacions de firmware: Regularly check the Waveshare Wiki or Raspberry Pi documentation for firmware updates and security patches for the RP2350A chip.
7. Solució De Problemes
If you encounter issues with your RP2350-Tiny Development Board, consider the following troubleshooting steps:
- La placa no s'encén:
- Ensure the USB cable is securely connected to both the board (via adapter if applicable) and the computer.
- Prova amb un port o cable USB diferent.
- Verify the power source is adequate (e.g., a powered USB hub if necessary).
- Placa no reconeguda per l'ordinador:
- Ensure the board is in bootloader mode if required for initial flashing (consult Waveshare Wiki for specific boot sequence).
- Reinstall USB drivers if prompted by your operating system.
- Try a different computer.
- Programa no en execució:
- Verifica que el teu codi es compila sense errors.
- Ensure the firmware was successfully uploaded to the board.
- Check for any short circuits or incorrect wiring in your external connections.
- The onboard RGB LEDs can provide status indications; refer to your program's logic for their meaning.
- FPC Cable Issues:
- Ensure the FPC cable is correctly inserted and latched into both the board and the adapter. Incorrect insertion can lead to connection failures.
