Hi,

I recently got a ST Nucleo board (Nucleo F070RB) and want to develop a device where it uses the on board USB (of the microcontroller) as a virtual com port.I've been able to configure a test project which has setup the USB Com port fine. (I am using the USB pins from the MCU and not the ST Link one).However I'm now at the stage of trying to figure out how to send stuff from the MCU to the host computer. Apart from the setup to do the configuration of the MCU I can't find any documentation of how to actually use it.If anyone would be able to help it would be appreciated.Thanks -Ryan Walmsley #stm32-usb-cdc-cubemx #stm32-usb-cdc-vcp

Hi walmsley.ryan.001,

I recommend you to check the ''STM32Cube USB device library'' User manual UM1734, at 6.5 Communication device class (CDC) part. You should take a look and run the ''CDC_Standalone'' example in

If you are using Standard Peripheral library then you can use this one for STM32F070.
