Dear all,
I try to control the speed of a stepper motor using USB 6210 card(s), I would like the speed of the stepper motor to change in a sin waveform. Should I input the counter with an array of sin waveform data points repeatedly, or update the frequency in a timed-loop dynamically using a sin function varying with time? Any suggestions or comments is highly appreciated. Thank you very much.
best,
Ian
