Thanks for your reply. I’m still confused. I can’t get it to operate reliably.
The Motor driver is IN1/IN2 mode. The single DC motor is connected to B- and B+ terminals. VM = 12 V. Logic voltage is 3.3V. I apply a PWM signal to PWM B the motor rotates in one direction only irrespective of HIGH or LOW logic level on DIR B. Varing the duty cycle does control the speed
I’m confused as to the truth table. For example, to go in the reverse direction I need a logic 0 on the IN1 input signal, if so, where is the PWM applied? I must be missing something basic
