Reading Pulses

RMCanaway

Hello, I’m curious if there’s any way to read pulses on the digital I/O pins.

I’m trying to read the duration of a pulse coming in

What pulse widths, and repetitions do you need to read ?

Have you looked at this ?

I'm attempting to program the HC-SR04 with the P8X32A-D40. when used with the arduino you can read the incoming pulse by ; pulseIn(Pin#, HIGH);. Im curious if there is something i can do with spin and achieve the same end product.

Moving this thread to Propeller 1 forum.

Yes, it can be done on the propeller. The link jmg posted provides the information you need to do that and so much more.

You can use the one of the counters to measure a pulse -- I do it quite a lot. If you give more specifics, others can be helpful with code.

Aren't talking about the ping sensor.
