CH32V203 support

[drom]

I see that TinyUSB supports CH32V307. Anybody tried porting it to CH32V203?

[Krasutski]

All USB peripherals are the same for all CH32F2x, CH32V2x, and CH32V3x family. The current dcd_ch32_usbhs.c Interface should work for all mentioned MCUs

@Krasutski @drom I tryied your recommendation. But I run into a problem:
../tinyusb/portable/wch/dcd_ch32_usbhs.c: In function 'dcd_init':
../tinyusb/portable/wch/dcd_ch32_usbhs.c:69:5: error: 'USBHSD' undeclared (first use in this function)

Searching for USBHSD doesn't yield any results. Recommendations?

[Krasutski]

You need to pull MCU libs, if you use CH32V203 you need to add support for new MCU, please check my similar PR

@Krasutski I'm not sure if i understood you correctly. Thanks for your support so far.
First, I have the MCU file headers included. But for instance, I don't have a USBHS_IRQn.
Eg. NVIC_EnableIRQ(USBHS_IRQn); does not exist as defined.
Instead there exists a USBHD_IRQn. E.g. NVIC_EnableIRQ(USBHD_IRQn); works.

Or let's take USBHSD. It's just undeclared. So the registers must be named differently, right?
Or did i just not include a file?
If the files are named differently? Is there an easy approach for porting?

I'm so stuck, please advise.

@Krasutski I tried it with your commit the F20X for a F20X MCU, and it compiles. If it works, i cannot test due to a lag of test board.

[greenscreenflicker]

It seems that there's some definitions missing in CH32V20x.
I added them manually to dcd_ch32_usbhs.c

[Krasutski]

No need to pay but I can do it in the next days maybe on the weekends
also, I don't have a board to double-check all so be ready for new issues :)

[greenscreenflicker]

@Krasutski Thank you for your offer. I'm willing to send you my evalboard for free by express. Or I test it myself, as you please.

If you wish to have the eval-board, we need to figure out a way to send me your address privately.

I personally don't feel to be a good-enough programmer for such pull requests.

[greenscreenflicker]

Hi, would be greatly happy about a pull request / support from your side. It turns out, that there are a lot of compability issues, as functions are missing in the wch definitions...
Let me know, as soon as I could try there something..

[Krasutski]

Just checked CH32V2x and as I see it doesn't support High-Speed USB, my PR was about HS driver, You need to use full-speed driver. The full-speed driver is under review now, you can pull this branch and test it: #2362

[greenscreenflicker]

Thank you for pointing me to that. Just tried to implement it. I have some issues there.

both usbfs and fsdev is supported by latest master.
