USB virtual com port for stm32f3discovery

Hi,

I plan to transfer the gyroscope value to PC through USB virtual com port. So I downloaded the latest version for the USB full speed device library for stm32(version 4.0). However, the projects, specifically the virtual com port example, are not supported for the f3 discovery(They work for other stm32 eval boards). How do I make these examples work for f3discovery? Can someone give me specific instructions?

Thanks,

SV

Never mind. I got it. Just got confused with the naming of the folder stm32303C-EVAL.. should be stm32F303C-EVAL..

Did you ever make it actually work?

Windows recognizes the port on mine, but I can't open the serial port.

Yep.. It works.. You have to open the port through a terminal.. I used a program called Free Serial Port Terminal.. Try it.

Problem was (is) unlike all other CDC USB firmware I've seen ST's demo doesn't support changing the virtualized baud rate.

Opening the port with 1152000 works.

I'm new to usb programing and also stm32f3 discovery kit. Just opened it couple of days ago. Can you help me with some basic program on virtual com port. The usb firmware examples donot run on discovery kit
