[Tinyos-help] [Help] How to transmit 4 byte messages to UART0 on telosb

[Nelly Chen]

Hi,

I am just starting to learn TinyOS and also not very familiar with  
coding in mcu. I've searched through the archive but still not  
understand how to transmit a 4 byte package to UART0 (pin 23) on Telosb?

The package is sent to a motor controller connected to the pin 4 on  
the 10-pin extension.

I used HplMsp430Usart interface, modified the baudrate, and send the 4  
byte signal when timer is fired. Is it right?

Any feedback or big picture of the structure is appreciated.

Thanks.
