RISC-V support like CH32V307 MCU

[dfsxn]

Hi,

Last year it was launched to the market the MCU CH32V307, which has the following features:

The CH32V305 and CH32V307 are interconnected microcontrollers, based on 32-bit RISC-V core, with hardware stack area and fast interrupt entry. Compared with standard RISC-V, the interrupt response speed is greatly improved. With single-precision float point instruction sets added and stack area extended, the CH32V305/7 has higher performance, the number of U(S)ART is extended to 8, and the number of motor timer is extended to 4. The CH32V305/7 provides USB2.0 high-speed interface (480Mbps) and has built-in PHY transceiver. Ethernet MAC is upgraded to GbE and integrates 10M PHY module.

Resources are available on GitHub and GitLab:

Even there's also a WCH Kicad Library on the way:

Could be a good option have OpenPLC support for CH32V307 MCU.

Thank you.

Kind regards,

If you are in China , you can try StarFive 2 board, it has tested with OpenPLC by their company. It is a RISC-V based board, has 2 RJ45 interfaces, you can take one for ehtercat
