Pololu Motor Driver Board with Freescale’s MC33926

/*
Here's an example code for controlling a Pololu Motor Driver Board with Freescale’s MC33926 chip using an Arduino:

Note that you may need to adjust the PWM frequency for the enable pin depending on your specific motor setup and desired behavior. Additionally, be sure to connect the motor power supply to the Vin and GND pins on the Pololu board and connect the motor to the M1A and M1B pins or M2A and M2B pins depending on which motor channel you're using.

const int EN_PIN = 2; // PWM enable pin
const int DIR_PIN = 3; // direction control pin
const int BRAKE_PIN = 4; // brake control pin
const int FB_PIN = A0; // feedback voltage pin

void setup() {
  // Set up the motor control pins
  pinMode(EN_PIN, OUTPUT);
  pinMode(DIR_PIN, OUTPUT);
  pinMode(BRAKE_PIN, OUTPUT);

  // Set the PWM frequency for the enable pin
  TCCR3B = (TCCR3B & 0xF8) | 0x01; // set Timer 3 to 31.25 kHz
}

void loop() {
  // Example usage: move motor forward at full speed
  digitalWrite(DIR_PIN, HIGH);
  digitalWrite(BRAKE_PIN, LOW);
  analogWrite(EN_PIN, 255);

  // Example usage: stop the motor
  digitalWrite(BRAKE_PIN, HIGH);
  analogWrite(EN_PIN, 0);

  // Read the feedback voltage
  int fbVoltage = analogRead(FB_PIN);
