Pinky,
You may use the MSP430GeneralIO interface for telosb/tmote. Suppose
you are using P6.3 to control your sensor:
In your module:
...
uses {
interface MSP430GeneralIO as P63;
...
}
...
call P63.selectIOFunc();
call P63.makeOutput();
call P63.setHigh();
...
In your configuration, wire YOUR_COMPONENT.P63 -> MSP430GeneralIOC.port63.
