STM32F1 custom USB
Posted: Mon Jun 29, 2015 9:02 am
Hi,
I try run USB as Vendor specific with libUSB driver.
At this moment, device it's correct detected in system, but I can't receive from host any data.
My code it's look that:
usbDataReceived look's that:
So, when I try send some information, then LED should be turn on, but this isn't happening.
I must activation EndPoint or something that?
I want transfer simple information like some short strings.
