Frequently Asked Questions

How do I program the Waveshare RP2350 development board?

The board supports drag-and-drop programming via its USB Type-C port. Connect it to your computer, and it will appear as a mass storage device. Simply copy your UF2 firmware file to the drive. For advanced development, you can use the Raspberry Pi Pico C/C++ SDK or MicroPython, configuring your IDE to target the dual-core RP2350 microcontroller architecture.

What camera modules are compatible with the onboard camera interface?

The development board's dedicated camera interface is compatible with popular modules like the OV2640 (2MP) and OV5640 (5MP). You connect the camera via the board's specific connector, and the image data is accessible through the RP2350's DCMI (Digital Camera Interface) peripheral, which can be programmed using the provided SDK libraries for image capture and processing.

Can I use both CPU cores (ARM and RISC-V) simultaneously on the RP2350?

Yes, the RP2350's dual-core, dual-architecture design allows you to run tasks on both the ARM Cortex-M33 and the RISC-V Hazard3 cores concurrently. The SDK provides mechanisms for inter-processor communication, enabling you to partition your application—for example, running a real-time control loop on one core and a graphics/user interface on the other for optimal performance.
