Example

#include <SegmentDisplay.h>
int latchPin = 9; // Shiftregister
int clockPin = 10;
int dataPin = 8;

int digit1 = 6; // cathode of the digits
int digit2 = 1;
int digit3 = 2;
int digit4 = 3;
int digit5 = 4;
int digit6 = 5;
int punkt = 7; // anode of the DP

SegmentDisplay segmentDisplay(latchPin, // tell the library the pins -> pinMode will be called
                              clockPin,
                              dataPin,
                              digit1,
                              digit2,
                              digit3,
                              digit4,
                              digit5,
                              digit6,
                              punkt);

void setup() {

void loop() {

  char tempTest[6][2] = {
    {'1', '.'},
    {'2', 'X'},
    {'3', '.'},
    {'4', 'X'},
    {'5', '.'},
    {'6', 'X'}
  };

  segmentDisplay.showChar(tempTest , 1000); // call display to show "1.23.45.6" for 1s
