Re: [Amforth-devel] Help getting started with a atmeg644PA

[Leon N M. <leo...@gm...>]

Awesome. That's just what I was looking for. I used the wrong uart_X.asm file 
and didn't modify USART_B_VALUE and USART_C_VALUE. Now everything works.

Is there a document that would have told me to do this?

Thanks for your help.
