I have got all motors running correctly on the L298n. I want to set up speed control with them also. According to this tutorial, to do that I attach a PWM GPIO to the Ena on the L298n. They also are using GPIO 25 as the PWM pin.
Is it correct to attach a PWM GPIO to the Ena to control the speed? I thought it was just Pin 18 that had PWM capabilities(RasPi3)? Or is something else going on here.
