I am going to use linx to program a stepper motor control VI. The stepper motor driver I use is A4988 and TB6600. The stepper's rotating speed depends on the frequency of pulse inout to the driver, so i use a digital square wave generator in linx to attain this request.
But now the output frequency 60Hz(which is shown in an escilloscope) is not identical with the frequency 1Hz I input in my VI. I do not have any idea about this problem.
I am asking this question on behalf of someone else, any input is very much apprecated.
