Because the PI40952 uses logic inputs, you can implement speed control by enabling/disabling the channel rapidly using PWM on the EN pin OR by toggling one of the input bits. The cleaner method is using the enable pin: void motorReverse() digitalWrite(A1

void setSpeed(int speedPercent) // 0 to 255 analogWrite(EN, map(speedPercent, 0, 100, 0, 255));
