Please refer to the post below for a more comprehensive description.
I’m recording the PWM signal sent to a stepper motor controller.
In this implementation, PWM duty cycle remains stable at ~50% but frequency changes from 127 to 500 Hz.
Channel 0 captures steps and
Channel 1 the direction.
I would like to display the frequency in an additional channel, for example as an analog measure just below. How to perform that?
Below is a mock-up with
Frequency (Hz) corresponding to
I’ve recorded the trace: Session 0 - PWM.sal (28.4 KB)
Similar question if frequency remains constant but duty cycle changes.
