Diagrama de pinout
The RP2350-Plus features 26 multi-function GPIO pins. This diagram illustrates the pin assignments and their configurable functions.
Figure 2: RP2350-Plus Development Board Pinout.
The pinout includes dedicated pins for power (VBUS, VSYS, 3V3_EN, 3V3), ground (GND), analog-to-digital converters (ADC), and various communication protocols like SPI, I2C, and UART. Programmable I/O (PIO) state machines offer flexible peripheral support.
Instruccions de configuració
1. Donant poder a la junta
The RP2350-Plus can be powered via the USB Type-C connector or a 3.7V Lithium battery connected to the battery header (9). When using the USB Type-C connector, ensure your power source provides sufficient current (e.g., a standard USB port or charger).
2. Connexió a un ordinador
Connect the RP2350-Plus to your computer using a USB Type-C cable. The board will typically appear as a mass storage device, allowing for drag-and-drop programming.
3. Entering Bootloader Mode
To upload new firmware or programs, the board needs to be in bootloader mode. Press and hold the BARRETA button (5) while connecting the USB cable or pressing the RESET button (7). Release the BOOT button once the board appears as a removable drive on your computer.
Operating the RP2350-Plus
Programming with C/C++ and MicroPython
The RP2350-Plus supports development using both C/C++ and MicroPython. Comprehensive SDKs and development resources are available to help you get started.
Figure 3: RP2350-Plus supports C/C++ and MicroPython development.
- SDK de Pico C/C++: The official Raspberry Pi C SDK can be used from the command line or popular integrated development environments (IDEs) like Visual Studio Code and Eclipse.
- MicroPython: MicroPython is a full implementation of the Python 3 programming language optimized for embedded hardware like the Raspberry Pi Pico.
For detailed programming guides and examples, refer to the official Raspberry Pi documentation for RP2040-based boards, as the RP2350A shares a similar architecture.
GPIO Usage
The 26 multi-function GPIO pins can be configured for various purposes, including digital input/output, analog input, PWM, and serial communication (SPI, I2C, UART). Consult the pinout diagram (Figure 2) and the RP2350A datasheet for specific pin capabilities and configuration details.
Manteniment
- Manipulació: Handle the board by its edges to avoid touching components, especially the microcontroller chip, to prevent electrostatic discharge (ESD) damage.
- Neteja: Si cal, netegeu suaument la placa amb un raspall suau i sec o aire comprimit. Eviteu utilitzar líquids o materials abrasius.
- Emmagatzematge: Store the board in an anti-static bag in a dry, cool environment when not in use.
- Actualitzacions de firmware: Regularly check for firmware updates from the manufacturer or community to ensure optimal performance and access to new features.
Resolució de problemes
Board Not Powering On
- Ensure the USB Type-C cable is securely connected to both the board and a reliable power source.
- If using a battery, verify it is charged and correctly connected to the battery header.
- Proveu un cable USB o un adaptador d'alimentació diferent.
Board Not Recognized by Computer
- Ensure the USB Type-C cable is a data cable, not just a charging cable.
- Try entering bootloader mode (hold BOOT button, then connect USB or press RESET).
- Prova amb un port USB diferent del teu ordinador.
- Install necessary drivers if prompted by your operating system (though typically not required for mass storage mode).
Code Not Uploading
- Verify the board is in bootloader mode (appears as a removable drive).
- Ensure the compiled firmware file (.uf2 for MicroPython, or appropriate binary for C/C++) is being dragged to the correct drive.
- Check your development environment for any error messages.
