Still waiting on that updated code...

hi Arrch

this is the new code, it works now, but i don't know how good it is

const byte ledCharSet[10] =
{
  B00100001,  //0 E-F-DP-C-D-B-A-G
  B11101011,  //1
  B01110000,  //2
  B11100000,  //3
  B10101010,  //4
  B10100100,  //5
  B00100110,  //6
  B11101001,  //7
  B00100000,  //8
  B10101000   //9
};

const int latchPin = 8;
const int clockPin = 10;
const int dataPin = 9;

void setup()
{
  pinMode(latchPin, OUTPUT);
  pinMode(clockPin, OUTPUT);
  pinMode(dataPin, OUTPUT);
  digitalWrite(latchPin, 0);
}

void loop() {
  for (int i = 0; i < 100 ; i++) {
    DisplayNumber(i);
    //delay(100);
  }
}

void DisplayNumber(int num) {
  int tens;
  int ones;
  if (num > 100 || num < 0) {
    num = 0;
  }

  ones = num % 10;
  if (num < 10) {
    tens = 0;
  }
  else {
    tens = num/10;
  }

  
  
  if(num>10){
  digitalWrite(latchPin, 0);
  shiftOut(dataPin, clockPin, MSBFIRST,  B00000001);
  shiftOut(dataPin, clockPin, MSBFIRST, ledCharSet[tens]);
  digitalWrite(latchPin, 1);
  delay(5);
  }
  digitalWrite(latchPin, 0);
  shiftOut(dataPin, clockPin, MSBFIRST,  B00000010);
  shiftOut(dataPin, clockPin, MSBFIRST, ledCharSet[ones]);
  digitalWrite(latchPin, 1);
  delay(5);

  Serial.print(num);
  Serial.print("\t");
  Serial.print(tens);
  Serial.print("\n"); 
}
