Hi Micheal,
Thanks for your reply. Actually, I am working on the tone detection part,
and the interrupt response seems very strange. The following is my original
code for this part, and I can see that the interrupt is coming continuously.
But when I probe the INT3 pin using an oscilloscope, I found the hardware is
working fine. I suspect the interrupt part is not working fine.
By the way, I am using the environment of Moteworks downloaded from Xbow
website. Thanks a lot!
command result_t StdControl.init()
{
call RadioControl.init();
call HPLUART.init();
call Leds.init();
call Serial.SetStdoutSerial();
call MicControl.init();
call Mic.muxSel(1);
call Mic.gainAdjust(64);
return SUCCESS;
}
command result_t StdControl.start()
{
call RadioControl.start();
call MicControl.start();
call MicInterrupt.enable();
return SUCCESS;
}
command result_t StdControl.stop()
{
call RadioControl.stop();
call MicControl.stop();
return SUCCESS;
}
async event result_t MicInterrupt.toneDetected()
{
call MicInterrupt.disable();
call Leds.redToggle();
TOSH_uwait(5000);
call MicInterrupt.enable();
__nesc_enable_interrupt();
return SUCCESS;
}
