Hello.
The goal is to make acquisition of a position sensor PWM signal (500 Hz, duty cycle 10-90%).
An external signal (pulse) is sent by a motor controller in move each x mm (typ. val x =0.02 mm).
I need to make a measurement (high level time & low level time) at each pulse, considering motor is moving continuously (typ. Speed = 30 mm/sec).
Board used : PCIe 6363
Dev software : Labwindows/CVI 2013 (any help in labview is welcomed too )
I succeeded in making a PWM Meas with a task CISemiPeriodChan, but not triggered with external signal, so I loose the position of each measurement.
Another solution may be another signal create (with another ctr) to “gate” measurement , but I did not succeed.
I have tried a lot of solution and samples, read a lot of post in forum without an working answer to my problem.
If someone could help me.
Thank you
