running text P10 with arduino uno

awal mula membuat ini karena ada pesenan yang menantang. munkin emang karena rezeki ya. rezeki yang tak bisa disangka-sangka.
googling sana sini akhirnya nemu juga.
kali ini saya akan share cara membuat running text dengan arduino
yang diperlukan antara lain:
1. modul P10
2. arduino uno
3. pcb yang sudah di desain

software :
1. arduino
2. library DMD dan TimerOne

langkah-langkah:
1. run software arduino
2. upload sketch  dibawah ini
#include <SPI.h>        //SPI.h must be included as DMD is written by SPI (the IDE complains otherwise)
#include <DMD.h>        //
#include <TimerOne.h>   //
#include "SystemFont5x7.h"
#include "Arial_Black_16_ISO_8859_1.h"

//Fire up the DMD library as dmd
#define DISPLAYS_ACROSS 1
#define DISPLAYS_DOWN 1
DMD dmd(DISPLAYS_ACROSS, DISPLAYS_DOWN);

/*--------------------------------------------------------------------------------------
  Interrupt handler for Timer1 (TimerOne) driven DMD refresh scanning, this gets
  called at the period set in Timer1.initialize();
--------------------------------------------------------------------------------------*/
void ScanDMD()
{
  dmd.scanDisplayBySPI();
}

/*--------------------------------------------------------------------------------------
  setup
  Called by the Arduino architecture before the main loop begins
--------------------------------------------------------------------------------------*/
void setup(void)
{

   //initialize TimerOne's interrupt/CPU usage used to scan and refresh the display
   Timer1.initialize( 3000 );           //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 );   //true is normal (all pixels off), false is negative (all pixels on)
  Serial.begin(115200);
}

/*--------------------------------------------------------------------------------------
  loop
  Arduino architecture main loop
--------------------------------------------------------------------------------------*/
void loop(void)
{
   dmd.clearScreen( true );
   dmd.selectFont(Arial_Black_16_ISO_8859_1);
   // Français, Österreich, Magyarország
   const char *MSG = "Fran""\xe7""ais, ""\xd6""sterreich, Magyarorsz""\xe1""g";
   dmd.drawMarquee(MSG,strlen(MSG),(32*DISPLAYS_ACROSS)-1,0);
   long start=millis();
   long timer=start;
   while(1){
     if ((timer+30) < millis()) {
       dmd.stepMarquee(-1,0);
       timer=millis();
     }
   }
}

3. sambungkan pcb dengan arduino dan kabel DMD p10
