Hi everyone,

Is there any example that explain how to merge USBD example and CDC ACM example?

Thanks everyone,

BR

This shouldn't be a problem, assuming you only have a couple of bytes of data to send for every sample. 

I have more than a couple of bytes to send every sample. What is the limit of CDC ACM?

I think that CDC ACM is not enough, for this reason I thought to use bulk endpoint. I think that it's the most suitable solution in my case.

Thank you so much,

BR

Hi

The limit depends primarily on which host OS you are using. In Windows we have found the CDC example to support data rates up to about 200kB/s (or 1600kbps). 

So up to 200 bytes every millisecond should be possible.
