Hi all,
I am in a robotics project that requires control of DC brushed motor. I have a controller box that output one bipolar control signal to tell the motor how much to turn.
I would like to turn this signal into two unipolar signal as described in the picture below, so that it can be fed into MCU to turn into PWM signal, before sending it to PWM motor driver (Pololu DRV8833) to drive the motor.
Any experts can point me the direction/reference on what I should be looking at? I am aware that there is this summing amplifier technique to raise the voltage level into unipolar signal.
Your kind assistance will be much appreciated. Also, please let me know if my description is not clear.
