3. Opstelgids

3.1 Aanvanklike verbinding

1. Connect the RP2350 USB Mini Development Board to your computer using a USB Type-C cable. The board will typically be recognized as a mass storage device.
2. Ensure your operating system has the necessary USB drivers. For most modern systems, these drivers are installed automatically.

3.2 Entering Bootloader Mode

To upload new firmware or programs, the board needs to be in bootloader mode. This is typically achieved by:

• Pressing and holding the BOOT button while connecting the board to your computer via USB.
• Alternatively, some development environments may allow entering bootloader mode via software commands.

4. Bedryfsinstruksies

4.1 Programmering van die Bord

The RP2350 USB Mini Development Board supports drag-and-drop programming. Once the board is in bootloader mode and recognized as a mass storage device, you can simply drag and drop compiled firmware files (e.g., .uf2 files) directly onto the board's drive. The board will automatically reset and run the new program.

4.2 Debugging and Communication

The board provides several interfaces for debugging and communication:

• SWD Interface: A 3-pin SWD (Serial Wire Debug) interface is available for hardware debugging, compatible with most ARM-based microcontrollers.
• UART-koppelvlak: A UART (Universal Asynchronous Receiver/Transmitter) interface is provided for serial communication, useful for sending and receiving data during development and debugging.
• I2C-koppelvlak: An I2C (Inter-Integrated Circuit) port is available for connecting various sensors and peripherals.
• USB Type-A Expansion Port: This port allows for USB 2.0/1.1 transmission via PIO, expanding connectivity options.

4.3 Supported Development Environments

The RP2350 microcontroller supports various programming languages and development environments, including:

• C/C++ SDK: The official Raspberry Pi C/C++ SDK can be used for command-line development or integrated into popular IDEs like Visual Studio Code and Eclipse.
• MicroPython: A full implementation of the Python 3 programming language optimized for embedded hardware, similar to Raspberry Pi Pico.

Waveshare Electronics provides extensive online development resources and example materials to assist with basic function implementations and complex project cases. These resources can be quickly integrated into your applications.

5. Onderhoud en versorging

5.1 Hantering Voorsorgmaatreëls

• Statiese Elektrisiteit: Electronic components are sensitive to electrostatic discharge (ESD). Always handle the board with care, preferably using an anti-static wrist strap or by touching a grounded object before handling.
• Vog: Protect the board from moisture and humidity. Store it in a dry environment to prevent damage.
• Fisiese stres: Avoid applying excessive force or bending the board, as this can damage components or solder joints.

5.2 Skoonmaak

If cleaning is necessary, gently wipe the board with a soft, dry cloth. For stubborn dirt, use a small amount of isopropyl alcohol on a cotton swab, ensuring the board is powered off and completely dry before re-powering.

5.3 Berging

When not in use, store the RP2350 USB Mini Development Board in its original packaging or an anti-static bag in a cool, dry place away from direct sunlight and extreme temperatures.

6. Probleemoplossing

If you encounter issues with your RP2350 USB Mini Development Board, consider the following common troubleshooting steps:

• Board Not Recognized: Ensure the USB cable is securely connected and functional. Try a different USB port or cable. Verify the board is in bootloader mode if attempting to upload firmware.
• Programmeringsfoute: Double-check your code for syntax errors. Ensure the correct development environment and SDK are installed and configured. Confirm the board is in bootloader mode.
• Geen krag/LED's af: Check the USB connection and power source. Ensure the cable is providing sufficient power.
• Perifere probleme: Verify wiring connections to GPIO pins. Ensure correct pin assignments in your code. Check power supply to external components.
