MicroPython v1.24 release adds support for RP2350 and ESP32-C6 microcontrollers, various RISC-V improvements
MicroPython has become one of the most popular ways of programming microcontrollers, and the just-released MicroPython v1.24 adds support for the widely-used Raspberry Pi RP2350 and Espresif ESP32-C6 microcontrollers and a range of other changes. Those include improved RISC-V support with native code generation, an updated Zephyr v3.7.0 RTOS with threading support, unified TinyUSB bindings across ports, a portable UART IRQ API, and enhanced mpremote recursive copy. Damien George goes into more detail about the RISC-V improvements: β¦ include an RV32IMC native code emitter, native NLR and GC register scanning implementations for 32- and 64-bit RISC-V, support for placing RV32IMC native code in .mpy files and also freezing it, and RISC-V semihosting support. Testing for RISC-V is done with the qemu and unix ports, and the support is utilised in the esp32 and rp2 ports. The Raspberry Pi RP2350 comes with both Arm Cortex-M33 and RISC-V cores, and the good [...]

Olimex RVPC is a one Euro RISC-V computer kit with VGA and PS/2 connectors
Olimex RVPC is one Euro RISC-V computer powered by a WCH CH32V003 RISC-V microcontroller and equipped with a VGA port for video output and a PS/2 connector to connect a keyboard. You wonβt be able to do much with this device as an end-user, but it does not matter since the RVPC open-source hardware board mostly targets the education market and is offered as a kit to be soldered to lower the selling price and to serve as a soldering learning kit. Olimex RVPC specifications: MCU β WCH CH32V003 32-bit RISC-V2A microcontroller up to 48 MHz with 2KB SRAM, 16KB flash (SOP8 package with 6x GPIOs) Video Output β VGA connector (3x GPIO used for Vsync, HSync, and RGB) Keyboard port β PS/2 connector (2x GPIO used) Programmer port β 2-pin header for CH32V003 programming through a board such as ESP32-S2-DevKit-LiPo-USB Misc β Buzzer (1x GPIO) and Red power LED [...]
