I have a circuit which outputs a PWM signal to control a motor's speed in response to an input sensor. The sensor amplifier, feedback circuit and PWM signal are based on a series of Op-Amps.
I'd like to convert the PWM signal to a frequency variation to control a stepper motor driver based on a TI DRV8834. Is there an easy way to do this in hardware without a micro-controller?
Thanks.
