Hi all,
We have found the problem. We wrote cbi(ETIMSK, TICIE3);, and it should be
sbi(ETIMSK, TICIE3); to enable interrupts.
Anyway, thanks a lot,
Andres

Subject: [Tinyos-help] Clock3 - Duty cycle
Date: Tue, 16 May 2006 16:28:13 +0200
Hi all,
We have micaz motes. We have installed TinyOS 1.1.7. We have bought a
temperature sensor, whose data is measured through a duty cycle. Then we
need a clock to measure it. We have write an application and it compiles
right, but the micaz mote does not work. We have tested that the interrupt
does not happen, we put a led in TOS_SIGNAL.
We do not know what the problem is. We have copied here the code of our
module. Can anyone help us?
Thanks in advance,
Andres
module DutyCycleM {
provides interface DutyCycle;
uses interface Leds;
}
implementation {
command result_t DutyCycle.start(uint8_t relojinit){
uint8_t data = inp(TCCR3B);
sbi(TCCR3B, ICES3); // Interrupt rising
cbi(ETIMSK, TICIE3); // Interrupt enable
outp(((data & 0xF8) | relojinit),TCCR3B); // Clock select
return SUCCESS;
}
command result_t DutyCycle.stop() {
uint8_t data = inp(TCCR3B);
outp((data & 0xF8),TCCR3B); // Timer/Counter stop
cbi(ETIMSK, TICIE3); // Interrupt disable
return SUCCESS;
}
command result_t DutyCycle.changeClock(uint8_t reloj){
uint8_t data = inp(TCCR3B);
uint8_t buffer = inp(ETIMSK);
cbi(ETIMSK, TICIE3); // Interrupt disable
sbi(TCCR3B, ICES3); // Interrupt rising
outp(((data & 0xF8) | reloj),TCCR3B); //0xF8 = 11111000
outp(buffer,ETIMSK); // Interrupt before
return SUCCESS;
}
default async event result_t DutyCycle.dataReady(uint16_t done) { return
SUCCESS; }
TOSH_SIGNAL(SIG_INPUT_CAPTURE3) {
uint16_t data = inw(ICR3L);
call Leds.set(7);
if (inp(TCCR3B) & 0x40)
cbi(TCCR3B, ICES3); // Falling
else
sbi(TCCR3B, ICES3); // Rising
sbi(ETIFR,ICF3); // Flag clear
__nesc_enable_interrupt();
signal DutyCycle.dataReady(data);
}
}
