Digital write not working on DUE but same code works Uno and Mega 2560

The following code works great on UNO and Mega 2560. It is a driver for an Elechous dual channel motor driver. I am using it to drive linear actuators with a joystick. the condition loops work but digital write pins do go high when required. see asterisks in code. Any help would be much appreciated

int SignalA= (0);//define input signal pin

int SignalB= (0);//define input signal pin

void setup()
{
pinMode(2,OUTPUT);
pinMode(3,OUTPUT);
pinMode(4,OUTPUT);
pinMode(5,OUTPUT);
pinMode(6,OUTPUT);
pinMode(7,OUTPUT);
pinMode(8,OUTPUT);
pinMode(9,OUTPUT);

// default mode is INPUT
Serial.begin(9600);

}

void LaIn()// Linear Actuator A IN
{
digitalWrite(2, HIGH); // in
digitalWrite(5, HIGH); // in
analogWrite(3,1); // in
}
void LaOut()// Linear Actuator A Out
{
digitalWrite(2, HIGH); // out
digitalWrite(3, HIGH); // out
analogWrite(5,1); // out
}
void LaStop()// Linear Actuator A STOP
{
digitalWrite(2, HIGH); // stop this pin goes high*************
digitalWrite(3, HIGH); // stop ********************this pin and pin 5 do not ******************
digitalWrite(5, HIGH); // stop
Serial.print(“hello”);
Serial.print("\t");
}
void LbIn()// Linear Actuator B IN
{

digitalWrite(8, HIGH); // in
digitalWrite(6, HIGH); // in
analogWrite(9,1); // in
}
void LbOut()// Linear Actuator B Out
{
digitalWrite(8, HIGH); // in
digitalWrite(9, HIGH); // in
analogWrite(6,1); // in
}
void LbStop()// Linear Actuator B STOP
{
digitalWrite(8, HIGH); // stop
digitalWrite(9, HIGH); // stop
digitalWrite(6, HIGH); // stop

}

void loop() {

digitalWrite(0, LOW);
digitalWrite(4, LOW); // set pin low
digitalWrite(7, LOW); //

SignalA=(analogRead(A0));
SignalB=(analogRead(A5));

Serial.print(SignalA);
Serial.print("\t");
Serial.print(SignalB);
Serial.print("\t");

Serial.println(" ");

if (SignalA > 900)
LaIn();

if (SignalB > 900)
LbIn();

if (SignalA < 400)
LaOut();

if (SignalB < 400)
LbOut();

if (SignalA > 400 && SignalA < 900)
LaStop();

if (SignalB > 400 && SignalB < 900)
LbStop();

delay(10);
}
