I have been working on an ASF4 project using the ATSAME53N20, and my own board that I built.
I have been successfully adding one library at a time with ASF4, writing the code, and testing it. So far, that is working well.
I am now trying to implement the USB port as a CDC class. There are a number of drivers and middleware options, and I'm not sure which all I need.
Also, I cannot seem to find any example code or documentation on how to implement this. There is a lot of info on ASF3, but that doesn't help.
Can someone please point me in the right direction?
