STM32 USB Connection
The USB connection between the STM32 and the computer is finally working.
I’ve tried the different USB programs from the StdPeriph Library
- Virtual COM Port
- DFU Programming
As I’m using Ride7 for programming, I can upload the project and sources if you want me too.
OBS: If you have projects which DOESN’T use the USB, you have to set the USB Disconnect jupmer to Ground (Pos. 1-2), as if not, the STM32 will stop in some kind of USB Interrupt trying to make a data communication with the computer, but it never comes as the STM32 doesn’t start one!
I discovered this Ã‚Â when I tried DFU’ing my 320×240 LCD code – and when I went back to normal .hex, it didn’t work – that was because I had to set the USB Disconnect to Ground!
