Posted on March 14, 2015 at 02:56I've used CubeMX to build a UV5 project that includes USB and CDC Device Class. Right out of the box the project compiles with no problem and runs. It enumerates as a Comm port.
Now all I need are a few simple functions to send and receive to the host. Something like:
int32 SendUsb(uint8_t *buf, uint32_t length)
{
returns number of bytes sent or -error code.
}
int32 ReceiveUSB(uint8_t *buf, uint32_t MaxLen)
{
Returns number of characters read or -error code
}
Would someone please suggest the proper library calls to achieve this. I've read the app note UM1725 and searched the web, but that didn't help me.
CubeMX seems to be a great tool for letting dummies use complex code like USB, and I hope I'm too dumb for it.
Thanks,
Dave
