I move from 8 bit MCU to SAM D20. I started to play with SAND20 xplained pro broad and using ASF. This time I have opportunity to configure SFR. But feel flexibility was gone.
I try to do serial communication using USART. Just want to echo the string i type in terminal after found CR / LF . I found some tutorial for serial com, which have callback function after received fixed buffer length. for that also i have to call "usart_read_buffer_job". It is not looks pure interrupt driven method.
is there any option in ASF can trigger RX interrupts for every byte received. So that i can check CR/LF there.
Sorry if i was missed out some fundamental of ASF.
