stm32 usb cdc communication [Copy link]

I was debugging the USB communication of stm32f4xx recently. I originally used HID communication, but the communication rate was not up to par. Then I wanted to change to cdc mode communication, but after the change, the computer could not recognize the USB interface. I would like to ask if you have encountered related problems or can provide related routines. Thank you! You can send it to hzddyx@163.com

Did you solve the problem? What is the speed? I have added an external PHY USB3300 and it only reaches 500KB/S  Details Published on 2019-5-3 15:17
