I am trying to evaluate Atmel Start (comparing it with coding "on the bare metal").
I am at the beginning of my experiences with the SAM D series, and a complete noob when it comes to Atmel Start.
My first test is to generate a project using an SERCOM/USART. After a bit of tinkering it seems to me that the I/O multiplexing chosen by the Atmel Start "code generator" is SERCOM-ALT. E.g. for SERCOM0 the auto-chosen I/O pins are (Rx/Tx) PA05/PA04.
Can I change the port multiplexing to SERCOM (rather than SERCOM-ALT)? How?
