Hiii,
I am currently using an STM32U5G9J-DK2 Discovery Kit and have configured USB in CDC_ACM mode in high speed. I generated a code default the usb device appears in device manager under ports as a virtual COM port. However, I would like to change this functionality so that it works as a WinUSB device instead.
- I got a example useful GitHub repository that provides a solution for converting CDC_ACM to WinUSB:
"https://github.com/MichaelTien8901/STM32WINUSB" .
this above link will show steps to convert STM32 USB CDC to WINUSB Device with HAL library.
- And the bellow link shows . Convert CDC to WINUSB by changing the descriptors and some HAL USB library files.
"https://github.com/MichaelTien8901/STM32WINUSB/commit/d6a8037b8c282652bd62fa252435c10598939752"
- I successfully implemented these changes on an STM32H7 series controller since its USB stack is quite similar to the STM32F4 series used in the example.
- However, I’m now facing challenges porting this to the STM32U5 series because its USB device stack is significantly different from the F4/H7 stack.
My question is:
- Has anyone successfully implemented WinUSB on the STM32U5 series?
- Which files and descriptors need to be modified in the STM32U5, USB stack to support WinUSB?
Any guidance or examples would be greatly appreciated.
Thank you!
