Hello Janos,
I haved modified the files as you said. But, I still cannot read data
from uart0.
I'm using IRIS. I want to read a sensor through Uart0. Some code I write
are :
components HplAtm128UartC;
App.Uart0RxControl -> HplAtm128UartC.Uart0RxControl;
App.HplUart0 -> HplAtm128UartC.HplUart0;
In the App file, use intefaces:
interface StdControl as Uart0RxControl;
interface HplAtm128Uart as HplUart0;
in the booted function:
call Uart0RxControl.start();
call HplUart0.enableRxIntr();
I thought async event void HplUart0.rxDone(uint8_t data) will be signaled when
the data are avaible. However, the program never runs into the function.
Can you tell me what I can do to deal with this probem?
Thanks .
Haixia Li

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.
