It’s basically the same as this:
Hi,
I was wondering if I could get some advice on how best to interface with my Saleae Logic 16 for a project I am working on.
Basically I have a stepper motor with a quadrature encoder and I am looking to characterise that motor within a mechanical system. The quadrature encoder outputs two square wave signals as shown below:

Basically the number of rising edges gives you the distance moved, the time between the rising edges gives you the velocity, and finally the phase of the two s…
for the beginning, it would be nice to see the count or position:
In the end I analyze Position, Speed and Acceleration. This is Excel Data with CVS Export.
But seeing the position would also help. I could not find this as function in my scope, Logicport analyser and Saleae, but I think more people need it.
Br, Wolfgang
