Hi everyone, please can anyone help me out? I want to get the duration of
an echo pulse through gpio/input pin. I interfaced PING ultrasonic range
finder with XM1000(TelosB) through GPIO pin. the sensor requires a pulse of
5micro seconds to trigger it, it then returns an echo whose duration I
neede
Hi,
The simplest way is probably LocalTimeMicroC, e.g.:
uint32_t time;
atomic{ //you don't want interrupts to mess up with the timing
call samplePin.makeOutput(); //make the pin an output
call samplePin.set(); //start ranging
call delay.wait (5); //for 5 micro seconds
call samplePin.clr()
