audio_v1_mic_multichan_template not working properly about cherryusb_wch HOT 9 CLOSED

I dont think wch support iso, so do not test audio or video.

from cherryusb_wch.

I did a some testing and found that usbd_audio_iso_callback never called, so ep_tx_busy_flag is not reset and

           while (ep_tx_busy_flag) {
            }

in audio_test runs forever

If you want to use audio, please select other chips, thanks. I think this issue is done.

A few things, make sure to add USBHS_UIE_ISO_ACT to the interrupt enable register. Then add the interrupt flag in your in the IRQhandler and handle properly. You have to modify the descriptors potentially for USB 2.0 High Speed to work. I have so far got it working with USB 2.0 Full Speed.

A lot must have went in this project, good job on the progress so far. Some notes,
I would suggest updating the readme and letting your users know what has actually been tested, what is in progress etc, like a checklist? Also quirks like const and other issues that users may face with this stack with respect to WCH chips. We're shooting in the dark right now.
