DELAY TIME TRIGGER EVENT COLLECTED BY PICO TO THE READY

Postby epiksrl » Mon Feb 06, 2006 5:12 pm

I HAVE TO TRIGGER A SIGNAL FROM A MOTORCYCLE AND I HAVE TO USE TRIGGER FOR CALCULATING ROUND SPEED.

adc200_set_trigger( TRUE,0,0,0,1000);
while(1){
adc200_run(1);
while(0 == adc200_ready()){
sleep(1);
}
adc200_stop();
<statements to calculate time/frequency between two spike>
}

if i work till 3000 round/sec I calculate well the round/sec if the round/sec increase I don't read well, my question is

HOW MANY DELAY TIME THERE IS FROM THE TRIGGER EVENT COLLECTED BY PICO TO THE adc200_ready() ANSWER 1

MY PROBLEM IS THAT WITH > 33 hz I DON''T GET ALL THE SAMPLE

PLEASE ANSWER ASAP, IT IS VERY URGENT

Hello,

It is not possible to put an exact number to this.

You will need to try using the trigger and buffer together to capture the full cycle. Estimating the timebase is down to the ADC200, you will have to experiment to obtain optimum settings.

Best regards,
Michael
