8 pin and 16 pin error #25
Comments
CDC doesn't work on Windows. There were some recent changes where you can reconfigure it to use other pins. It should work fine on other variants of the chip. |
I have downloaded the latest code, but it didn't work on 8 and 16 pin version, I found a specific configuration than kind of worked, port A, dm 2, dp 1. It does not show any error like 'invalid usb descriptor', it appears in usb device manager, but it does nothing. |
Are those ports reconfigurable? Also did you try swapping them? |
PC1, PC2, PC4 gamepad demo, Test OK. usb_config.h
|
I have linked the above message in the README. Closing issue now. Thank you for testing. |
i design my own device but not work |
Please clarify - what errors are you receiving on the OS end? Have you tested this with a known-good board configuration? Please also share your schematic. (And it probably makes sense to open a new ticket) |

I have passed this issue off to some folks in my Discord, a few who got the SOP-8 version working. You may want to join that discord and see if they can help more. I've never used the SOP-8 version of the 003. https://discord.gg/CCeyWyZ I don't see any reason port C "shouldn't" work, but also, I don't have experience making it work. Hopefully someone on the discord can shine some light. |
I worked! its amazing, all examples worked but cdc, com port doesn't work.
I tried the code on ch32v003 over 8pin and 16pin version, with no luck.
Is there a way to make it work on those versions, or is the code for the 20 pin version only?
Thanks.!
