NUCLEO-U083RC - USBX CDC

Hi,

I am trying to get the USBX CDC working on a NUCLEO-U083RC, but with no luck.

I have tested that the USB port (PA11 and PA12) works, because I can do firmware upgrade using the STM32CubeProgrammer.

But I cannot find any example on how to get the USB CDC (Virtual Comport) working.

I have spend most of a day trying different examples, but nothing seems to work for me.

Do anyone have any help to offer regarding a working example ?

 

Best Regards

Jakob

    Hi @JJust.2 

    Are you using flying wires to USB micro b connector? Did you try following the example provided here STM32CubeU0/Projects/STM32U083C-DK/Applications/USBX/Ux_Device_CDC_ACM at main · STMicroelectronics/STM32CubeU0
