Re: [avr-gcc-list] basic UART problem / example

[Hugo González Monteverde]

Have you tried polling mode first? There is a common gotcha where you 
have to disable overall interrupts so that you get the data from the 
UART input register and avoid the interrupt to keep trigering.

Maybe if you can post a copy of your ISR...
