Description

The Waveshare RP2350-Touch-LCD-1.46 is a compact, all-in-one development platform centered on the Raspberry Pi RP2350B microcontroller. This chip’s unique dual-architecture design pairs an Arm Cortex-M33 core with a Hazard3 RISC-V core, providing developers with flexibility in toolchain selection and task partitioning for complex embedded applications. The board is engineered for low-power operation, supporting various sleep modes to extend battery life in portable devices.

Its integrated 1.46-inch high-resolution IPS display with capacitive touch enables the creation of responsive graphical user interfaces without external components. The inclusion of a 6-axis IMU, real-time clock, and ample memory (16 MB Flash, 520 KB SRAM) makes it suitable for data-intensive projects like wearable tech, smart controllers, and interactive HMI panels. The USB-C interface simplifies both power delivery and firmware updates, streamlining the development workflow from prototyping to deployment.

Key Features

  • Dual-Architecture Processing: Leverage both Arm and RISC-V cores for optimized performance and development flexibility.
  • High-Resolution Round Display: 1.46-inch IPS screen with 412x412 pixels and 5-point capacitive touch for sleek, modern UI designs.
  • Integrated Motion & Time Sensing: Onboard 6-axis IMU and RTC enable features like gesture control, activity tracking, and time-stamped data logging.
  • Programmable I/O (PIO) Support: 12 dedicated PIO state machines allow for precise, processor-independent control of custom interfaces and protocols.
  • Expandable System Memory: Large 16 MB Flash storage and microSD card slot support complex applications and extensive data sets.
  • Simplified Development Workflow: USB-C connector supports drag-and-drop programming, eliminating the need for external programmers.

Frequently Asked Questions

How do I program the Waveshare RP2350 development board?

You can program the board using the Raspberry Pi Pico C/C++ SDK or other RP2350-compatible toolchains. Connect via the USB-C port for drag-and-drop UF2 file flashing or for serial debugging. The board appears as a mass storage device when booted in BOOTSEL mode, allowing you to simply copy firmware files. For advanced development, use an IDE like VS Code with the official SDK for debugging and direct flash programming over the USB serial connection.

What is the purpose of the dual-core, dual-architecture (Arm + RISC-V) design?

The dual-architecture design provides flexibility in software development and task optimization. You can assign real-time, deterministic tasks to the RISC-V Hazard3 cores and run higher-level application logic on the Arm Cortex-M33 cores. This allows for efficient partitioning of workloads, potentially simplifying complex firmware. It also gives developers choice in toolchains, enabling the use of specialized compilers and libraries tailored for either Arm or RISC-V instruction sets.

Can I use this board with LVGL for creating graphical interfaces?

Yes, this board is an excellent platform for LVGL (Light and Versatile Graphics Library). The 1.46-inch IPS display with capacitive touch provides a high-quality output and input device, while the 16 MB of Flash and 520 KB of SRAM offer sufficient memory for storing graphics assets and running the LVGL rendering engine. You will need to port the LVGL display and touch drivers to the RP2350's GPIO and I2C interfaces, which is straightforward given the available documentation and examples for similar microcontrollers.

How do I power the board for a portable/battery-operated project?

For portable operation, connect a 3.7V Li-Po or Li-Ion battery to the dedicated 'BAT+' and 'GND' pins on the battery header. The board includes charge management circuitry. You can also power the board via the USB-C port with a standard 5V supply. Ensure your firmware utilizes the RP2350's low-power sleep modes to maximize battery life. The onboard RTC can maintain timekeeping during deep sleep, allowing for periodic wake-up and data logging cycles.
