MQX4.1 looking for a good USB CDC device example application code

[huishao2]

Is there a good USB CDC device only example application code for MQX4.1? Hopefully better than the one at usb\device\examples\cdc\virtual_com. In addition, I only see IAR build folder like cdc_vcom_twrk21d50m\. What I am working on is k20d50m. Does the difference matter?

I need it as a start point to implement a simple USB CDC device application on MK20DX128VFM5.

Thanks!

Hi Hui,

I agree the VCOM is simplistic and only shows echo response from Kinetis while typing on the PC side.

I have made a request to either enhance this demo or create a separate true VCOM that could be used to replace using a UART.

Thank you for the feedback.

Regards,

David

Hi David,

I too am looking for a little more extensive of an example, and/or API reference for the CDC Serial comms.  Can you point me in the right directions?
