Matt,

Take a look in this directory:

tinyos-2.1.0/tos/chips/atm128/

Files:

HplAtm128Uart.nc
HplAtm128UartP.nc
HplAtm128UartC.nc

These are the components that control the UART interfaces. Look for UART1 in those files. You might also want to look at

tinyos-2.1.0/tos/platforms/micaz/MotePlatformC.nc

which defines the pin used for serial input/output(UART0 i believe)

Hi all,

I want to reuse the USART1 for my own peripheral on a micaz, and I'm struggling to find the USART hpl in the TinyOS code.

My understanding is that the USART is used only for the flash chip and I can find the SPI bit banging code (HplAt45dbIOP.nc) which operates over the USART, but I can't find the actual USART config code.

Presumably this is somewhere in the Atm128 folder... can anyone clarify ?

Many thanks,
Matt
