Reading Digital caliper with Arduino

[EdK]

Chuck,

I don't get a compiler error when I insert the line of code Arvid suggested. Here's my complete program. I don't have the board yet, it should be here by Wednesday.

Code:

//Simple Digital Calliper Reader
//See http://j44industries.blogspot.com/

// Pin Declarations
int dataIn = 16;
int clockIn = 15;

// Variables
int clock = 1;
int lastClock = 1;
unsigned long time = 0;
unsigned long timeStart = 0;
int out = 0;


void setup() {
 // Pin Set Up
 pinMode(dataIn, INPUT_PULLUP);    
 pinMode(clockIn, INPUT_PULLUP);  


 Serial.begin(115200);
 Serial.println("Ready: ");
}


void loop(){

 lastClock = clock;
 clock = digitalRead(clockIn);

 if (lastClock == 1 && clock == 0){
   out = digitalRead(dataIn)+digitalRead(dataIn)+digitalRead(dataIn); // Tripple sampling to remove glitches
   Serial.println(micros());
   if((micros() - time) > 800){
     Serial.println(" ");
   }
   else if((micros() - time) > 400){
     Serial.print("  ");
   }

   if (out > 1){
     Serial.print("1");
   }
   else{
     Serial.print("0");
   }
   Serial.print(",");
   time = micros();
 }
}
