Hello folks!

We have been making slow progress on the ACC Handle code for Arduino. I`m using a Leonardo and so far we have a stable way of reading the ACC Values.

With the code below we can Serial Print and read the values. Next step will be stopping the loop and adding keyboard.Print commands.

// Arduino Leonardo Rev3.0 
// This code is for all Scania 4-Series
// ACC HID control for ETS2
void setup() {
  // initialize serial communication at 9600 bits per second:
  Serial.begin(9600);
}

// the loop routine runs over and over again forever:
void loop() {
  // read the input on analog pin 0:  
  int analogValue = analogRead(A0);
  // print out the value you read:
  Serial.println(analogValue);
  delay(100);        // delay in between reads for stability
  if (analogValue > 870 && analogValue < 890) // read the analogue input into variable analogValue
  {
   //ACC is in the OFF Pos
   Serial.print("ACC OFF");
   delay(1);
  }
  else
  if (analogValue > 950 && analogValue < 965)
  {
   //ACC is in the ON Pos
   Serial.print("ACC ON");
   delay(1);
  }
   else
   if (analogValue > 985 && analogValue < 995)
  {
   //ACC is in the ON Pos and RET is Pressed
   Serial.print("ACC ON+RET");
   delay(1);
  }
  else
  if (analogValue > 1000 && analogValue < 1011)
  {
   //ACC is in the ON Pos and RES is Pressed
   Serial.print("ACC ON+RES");
   delay(1);
  }
   else
   if (analogValue > 1012 && analogValue < 1025)
  {
   //ACC is in the ON Pos and ACC is Pressed
   Serial.print("ACC ON+ACC");
   delay(1);
  }
}
