DC Motor Control with DRV8801

Using Arduino Motors, Mechanics, Power and CNC

Hi, my aim is to just control the direction and speed of the Micro-Metal Gearmotor with this motor driver DRV8801.

For now my code is

int PWM1=  2;
int DIR1= 22;
int Brake1= 28;

void setup() {

  pinMode(PWM1, OUTPUT);
  pinMode(DIR1, OUTPUT);
  pinMode(Brake1,OUTPUT);
  digitalWrite(DIR1, LOW);
}

void loop() {
analogWrite(PWM1, 200);
delay(2000);
digitalWrite(DIR1, HIGH);
analogWrite(PWM1, 50);
}

But the motor is neither changing direction nor speed. What am I doing wrong?

int PWM1=  2;
analogWrite(PWM1, 200);

What Arduino board are you using? An Uno (or equivalent) has PWM on pins 3,5,6,9,10,11. Not pin 2.

int PWM1=  2;

analogWrite(PWM1, 200);

I'm using the mega 2560 R3

Has been solved, the solder was cold and wasn't connecting the DIR properly.
