ch32 usbFS

[nikitos1550]

Hello! Did somebody actually tried usb full speed device controller?

Before I tried ch32v103, not I changed chip to ch32v303, that has same with ch32v307 USBFS controller.
But I cannot make it work :-(

I remember that there are some issues with WCH, but I don't believe that it fully not working.

Same log with data MCU sent to host.

[sakumisu]

Only support CH32V307, although their ip is the same ,but is not the same too, thanks.

[nikitos1550]

I also have ch32v305 chip, I replace it on the board and try it. I don't believe, I want see myself.

[nikitos1550]

Same with 305 chip. This is really strange. Later I will get usb analyzer and can inspect what is really going on the bus. Now seems I cannot use cherryusb :-(

[sakumisu]

Sorry , we do not have other chips and do not know if their same ip is actually the same. You can use v307.

[nikitos1550]

Sorry , we do not have other chips and do not know if their same ip is actually the same. You can use v307.

Can I donate you some hardware, so you can try run your project on it?

[HaiMianBBao]

Please turn off the log or lower the log level before testing.

[nikitos1550]

Please turn off the log or lower the log level before testing.

I will wait until USB analyzer will come to me (maybe several weeks later) and continue testing with it. For sure will try with and without log. Thanks for advice, yes I know that log can affect timing, moreover I am using 115200 uart log, that is not very fast.

[nikitos1550]

Finally I choosed tinyusb stack (https://github.com/hathach/tinyusb) instead of cherry (sorry).
I managed ch32v307 usbfs and ch32v103 usbhd work on it. There is usbd controller that I also want bring up. With these four drivers all ch32 usb peripherals should work. maybe later will make PR to tinyusb, Follow up if you interested.
