[libopenstm32-devel] CDC ACM

[Matjaz J. <ja...@gm...>]

Hi,

another question about using USB CDC ACM. Example and some upgrades to
it were quite successfull. There are some problems using it as virtual
com port:
- If I want to make usb to RS232 bridge, where to detect the set up
for COM port (baudrate, parity,....)?
- receiving data from PC shows no problem. I've used example and
upgrade it to reply for incoming data. But sending the data to the PC
was problematic,
because I've probably overfilled/corrupted the output data pipe. My
question is, how to check if the outgoing bufffer is empty and is
ready for new data?



best regards, Matjaz
