Inquiry About Support for Additional Models

[recalci]

I'm curious if there are any plans to support additional models. Some models, although not starting with "ch32," still use the same Qingke series core.

For example, the CH643's register map primarily differs from the CH32X035 in that it includes LEDPWM functionality.
It would be great to know what’s on the roadmap regarding support for these models. Thank you!

If you have a CH643, pretend it's an x035 - can you try using it and seeing where there's resistance? It should be pretty easy to bring up more chips!

[recalci]

I have CH643 chips, and I will start testing them once I get the pcb in a few days.
I’ve used the CH641 as a CH32V003 and didn’t find any issues so far.

Please let me know what you find!

[recalci]

I've tested it. Aside from electrical characteristics, LEDPWM, remapping, and number of gpio and adc channels, they are essentially the same.

It would take some thinking to select appropriate #define's for this... Does it make sense to just #define ch32x035 and go from there or should there be direct support for that in ch32v003fun?

[recalci]

Thanks for considering support for CH64x.
I don't have much experience in this area.
I'm currently working on adding support for WCH MCUs with USB PD and BC1.2 in Zephyr. Since Zephyr uses device tree, both approaches are fine.
However, CH641 and CH645 don't have nearly identical models, so direct support might be better to keep things consistent.

Hi @recalci - do you have a link to the source for that graphic by any chance please? Thanks.

Sure! The graphic can be found on the WCH website in Chinese: https://www.wch.cn/products/productsCenter?categoryId=5

Thanks a lot @recalci - I had looked at their website but failed to find that page. 👍
