Re: [Tinyos-help] Help IRIS uart0 bard rate
Hello Janos, I use Uart0RxControl.start(). Is it ok? Do I need to use other interface? Thanks.

Modify (or create a shadow copy) of chips/atm1281/HplAtm128UartC.nc in which you change the line ubrr0 = call Atm128Calibrate.baudrateRegister(PLATFORM_BAUDRATE); to ubrr0 = call Atm128Calibrate.baudrateRegister(1200); The value returned by Atm128Calibrate.baudrateRegister(1200) should be around 383.
