USBD example + CDC ACM example

[alexlöddeköpinge]

Hi everyone,

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

Thanks everyone,

Thanks for your answer,

I have to implement a composite device. I use the CDC ACM class to transfer  from nrf52840 to pc a low-speed signal.

I also need to transfer data from ADC to PC and I want to do this using bulk transfer. I need bulk transfer because I want to transfer packaged real-time data.

Hi 

The CDC ACM class is also based on bulk transfers, so I don't think that should be an issue. 

An important aspect of bulk data is that you are not guaranteed to get a packet through on every USB event (every millisecond), but you are guaranteed that all data will be transferred eventually. 

How much ADC data do you need to send every second?

Best regards
