Hello,
My code is below. I am trying to program my Tmote Invents to detect a sound
at a certain level and then change LEDs. The way it should work is the red led
is set upon start up. I have also set up a timer to fire every 5 seconds
5*1024. What should happen is that when I clap, the green Led is turned on and
the red Led is turned off. Once the 5 second interval has completed, I then
want the green light to cut off again and return to red. Can anyone see what
I'm doing wrong. The code compiles and the red light is set, but I am unable to
trigger the green light.
module MicDetectM
{
provides interface StdControl;
uses {
interface Timer;
interface Leds;
interface SensorInterrupt as MicInterrupt;
interface Potentiometer as MicInterruptThreshold;
interface Potentiometer as Vrc;
interface Potentiometer as Vrg;
//interface Microphone; to be incorporated
}
}
implementation
{
/*Declare Constants and variables */
/* Put Constant Here , */
enum {TIMER_INTERVAL = 5*1024}; /* Timer repeat every 5 seconds */
enum {MIC_INT_THRESH = -40};
/* Declare Tasks Here */
/***** Start Control Here ***/
/**** TIMER *****/
event result_t Timer.fired() {
/* reset memory if a interupt has not occured */
call Leds.greenOff();
call Leds.redOn();
return SUCCESS;
}
/********** Start Application *********/
command result_t StdControl.init() {
call Leds.init();
call MicInterruptThreshold.set(MIC_INT_THRESH);
call Vrc.set(1);
call Vrg.set(0);
return SUCCESS;
}
command result_t StdControl.start() {
return call Timer.start( TIMER_REPEAT, TIMER_INTERVAL );
return call MicInterrupt.enable();
//return SUCCESS;
}
/**** Turn Stuff Off **/
/******* code to be executed upon finishing the recording *******/
//async event void Microphone.done( void *addr, uint16_t length ) {
//post recordingFinishedTask();
//}
event void Vrg.setDone( uint8_t value, result_t result){}
event void Vrc.setDone( uint8_t value, result_t result){}
event void MicInterruptThreshold.setDone(uint8_t _gain, result_t _result) { }
async event void MicInterrupt.fired() {
atomic { call Leds.greenOn();
call Leds.redOff(); }
}
/*********************End Application ********/
command result_t StdControl.stop() {
return call MicInterrupt.disable();
//return SUCCESS;
}
}
