Pin identifier for Arduino Boards

[Rav3nX]

Thought I would share this; its a script to identify input pin numbers for helping setup DCS BIOS etc; Lots of times I have pined through a giant connector; and rather than heaps of work keeping track of it all, its easier to work it out at the end.

 

 

So here you go; just upload this to the board then open the serial monitor in arduino IDE. Press your buttons and you will get the pin number.

 

EDIT: Obviously this is built for the MEGA, change loop numbers to suit your pin count.

 

//Pin state change serial printer

int PinStates[54];
int A_PinStates[16];
int APinVals[16];
//char aPins[16] = {'A0', 'A1', 'A2', 'A3', 'A4', 'A5', 'A6', 'A7', 'A8', 'A9', 'A10', 'A11','A12', 'A13', 'A14', 'A15',};
static const uint8_t analog_pins[] = {A0,A1,A2,A3,A4,A5,A6,A7,A8,A9,A10,A11,A12,A13,A14,A15};

void setup() {
 
  Serial.begin(9600);
  for(int i = 3; i <= 53; i++) {
    pinMode(i, INPUT_PULLUP);
  }

  for (int i = 0; i < 16; i++) { 
     pinMode(analog_pins[i], INPUT_PULLUP);
  }

}

void loop() {

for (int i = 3; i <= 53; i++) {
   int PinNumber = i; //i + 4;
   int CurrentState = digitalRead(PinNumber);
   if(CurrentState != PinStates[i]) {
     Serial.print(PinNumber);
     Serial.print(" D");
     Serial.print(i);
     Serial.print(" [ ");Serial.print(CurrentState);
     Serial.println(" ]");        
   }
   PinStates[i] = CurrentState;
}

for (int y = 0; y <= 16; y++) {
   int PinNumber = y; //i + 4;
   int CurrentState = digitalRead(analog_pins[y]);
   if(CurrentState != A_PinStates[y]) {
     Serial.print(analog_pins[y]);
     Serial.print(" A");
     Serial.print(y);
     Serial.print(" [ ");
     Serial.print(CurrentState);
     Serial.println(" ]");        
   }
   A_PinStates[y] = CurrentState;
}
delay(10);
   
}
  
}
