Timer Lomba Tamiya 3 Jalur / Line

Timer Lomba Tamiya 3 Jalur / Line

      Pada kesempatan kali ini saya akan menjelaskan mengenai bagaimana cara membuat sebuah alat yang digunakan untuk timer lomba tamiya dengan spek yaitu 3 jalur mobil mini 4 wd dan juga alat ini menggunakan penampil dmd p10 dan sensor optocoupler. untuk lebih jelasnya berikut adalah komponen dan kodingnya.

a. Komponen

b. Program Arduino IDE

#include <Wire.h>

#include <SPI.h>        //SPI.h must be included as DMD is written by SPI (the IDE complains otherwise)

#include <DMD.h>        //Library DMD yang menyediakan fungsi penampilan teks, gambar dsb

#include <TimerOne.h>   //Library peripheral Timer1 untuk menjalankan prosedur pindai panel DMD

#include <Time.h>     //Library waktu yang menyediakan tipe data, struktur, dan obyek waktu

#include "Arial_black_16.h"

#include "Arial_Black_16_ISO_8859_1.h"

#include "Arial14.h"

#include "DejaVuSans9.h"

#include "Droid_Sans_12.h"

#include "Droid_Sans_16.h"

#include "DejaVuSansItalic9.h"

#include "Mono5x7.h"

#include "SystemFont5x7.h"

#define WAKTU_TAMPIL_JAM      10    //detik

#define WAKTU_TAMPIL_KALENDAR 5     //detik

#define DISPLAY_COLUMN_COUNT  2

#define DISPLAY_ROW_COUNT     1

#define PIXELS_PER_COLUMN  32

unsigned char show = 0;

char lineBuff[20];

char lineBuff2[20];

int lineA;

int lineB;

  dmd.clearScreen( true );   //true is normal (all pixels off), false is negative (all pixels on)

  Serial.begin(9600);

   //initialize TimerOne's interrupt/CPU usage used to scan and refresh the display

  Timer1.initialize( 1000 );           //period in microseconds to call ScanDMD. Anything longer than 5000 (5ms) and you can see flicker.

  Timer1.attachInterrupt( ScanDMD );   //attach the Timer1 interrupt to ScanDMD which goes to dmd.scanDisplayBySPI() 

  //clear/init the DMD pixels held in RAM

  dmd.clearScreen( true );

}
