I am (of course) new to ASF & Atmel Start and I am trying to register callbacks. I download Start code for the Sam D20 USART sercom4, which writes "hello world" to sercom/PB08. I am now trying to add callbacks so I can receive.
Now, I may be missing something but it looks like Amtel did not provide me with the #include files to do this. Furthermore the studio does not recognize usart_async_register_callback and I also can't find struct usart_async_descriptor. struct usart_async_descriptor is needed as a
parameter of to the actual callback function.
How can I add the functionality to my prog
Edit PLEASE disregard
