Hello,
I hope you are doing well.
Recently, I was reading about the 10-cent CH32V003 RISC-V MCU and just wondered if it would be possible to consider adding support in a future uLisp version.
This seems to be the “official” Arduino core.
Best regards,
Yes, I’ve been thinking about the CH32 processors for a while.
The CH32V003 probably isn’t suitable because it only has 16K of flash and 2K of RAM, less even than an Arduino Uno (which has 32K of flash). Also, RISC-V code tends to take up more flash than AVR or ARM code.
However, there are some other processors from WCH that do look promising:
As far as I can see, only the first of these has support from the official Arduino core. Does anyone have experience of using it?
Hello,
Thanks a lot for your feedback. I was checking what appears to be the official store. Are you referring to this?
It doesn’t look beginner-friendly; somehow it’s using a double-pin arrangement. It would be great if there was something like the ESP32 or Pico form factor!
Here official MCU specs.
Best regards,
Hello,
Just to add to the previous comments, here is another form factor, though from a “non-official” store.
However, I suspect that the Arduino core will support “official” boards only.
Best regards,
I hadn’t got as far as thinking about what board to use, but I’m pretty sure the Arduino core for that processor will work on any board; the pins may just be in a different order.
Hi,
Ok, I will try a simple Arduino example.
I just bought both boards; hopefully, they will arrive in a few weeks!
Best Regards
