Hi,
I want to generate frequency signal between 0 to 440 Hz to drive step by step motor.
I do it with ordinary tor output and count cycle of Rpi. But precision is limit by cycle max of Rpi. Over 500µs cadenced cycle : not work well.
How can I do it with better solution ? Is it possible to use sound output ?
Thank for your help.
