USART1 instead of USART0 #47

Closed zdravke closed 5 years ago

I'm suspecting optiboot_m328pb.hex is using USART0. Is there a way to use USART1 instead?

Yes, as default USART0 is used. To use another USART interface, Optiboot has to be re-complied with UART set to the respective port: https://github.com/watterott/Wattuino/blob/master/software/Optiboot/optiboot.c#L127
