Question
Help with USB CDC
Posted on July 05, 2018 at 11:12
I have interfaced an STM32F446RE in USB-CDC mode. I have made it device only, I set the middleware to CDC, and I set the clock appropriately too. I also added the change to CDC_Transmit_FS function. When I try to use CDC_Transmit_FS in a loop to try and print something in the terminal window (hyperterminal is used), even after giving large delays, nothing is getting printed on the terminal. The drivers have also been installed and in device manager I see, STMicroelectronics STLink Virtual Com port. I changed the size of stack and heap as well, and I have changed the packet sizes to 64 too.
