USB device example

[kekcheburec]

Hi, @andelf !

I saw that in this hal there is a USB device implementation, but there is no example for working on the same ch32v203 :(

Or is the implementation not working at all?

[andelf]

I haven't tested it yet. CH32V has two completely different USB IP cores. One is USBD used in CH32V203, which is almost the same as STM32's. So I just copied the implementation.

Another IP core is USBH(OTG) used in some other chips.

Do you have any plans to work on the OTG peripheral in the near future? If not, we're interested to help out and avoid duplicate work.

Hi @Dummyc0m !

Personally, at the moment I do not plan to implement usb otg peripherals. I just wanted to find out if what is already in the repository works and got an answer.

In general, you can close the issue.

Sorry, I was actually hijacking the issue and asking @andelf to see if they have any plans.

Why close the issue as complete? There's no USBD example
