USB OTG on STM32

Hello,

I'm trying to do the following thing:

a STM32 working as USB virtual com port. For that ST provide VCP example.

And on the other side, instead to plug a PC to recognise this VCP, I would like to plug another STM32.

Apparently, this second STM32 needs to have USB OTG.

Does anyone know if ST provides a USB OTG library for STM32?

Thanks in advance.

Hello stm321,

STM32 doesn't support USB OTG, it provides the device capability only. In other words, the STM32 cannot be a host it can be only a device!

To connect two STM32s together, just using the UARTs would be far simpler. 8-)
