最近在做Arduino 的程式應用，目的是先讓RED矩陣的數字會亮

原課本程式碼為  如下

#include <SPI.h>
const int slaveSelect=10;
const int decodeMode=9;
const int intensity=10;
const int scanLimit=11;
const int shutDown=12;
const int dispTest=15;
byte i;
const int col=8;
const byte character[10][8]=  //PABCDEFG               
  { {0x00,0x00,0x7f,0x41,0x41,0x7f,0x00,0x00},    //0
    {0x00,0x00,0x00,0x00,0x00,0x7f,0x00,0x00},    //1
    {0x00,0x00,0x79,0x49,0x49,0x4f,0x00,0x00},    //2
    {0x00,0x00,0x49,0x49,0x49,0x7f,0x00,0x00},    //3
    {0x00,0x00,0x0f,0x08,0x08,0x7f,0x00,0x00},    //4
    {0x00,0x00,0x4f,0x49,0x49,0x79,0x00,0x00},    //5
    {0x00,0x00,0x7f,0x49,0x49,0x79,0x00,0x00},    //6
    {0x00,0x00,0x01,0x01,0x01,0x7f,0x00,0x00},    //7
    {0x00,0x00,0x7f,0x49,0x49,0x7f,0x00,0x00},    //8
    {0x00,0x00,0x4f,0x49,0x49,0x7f,0x00,0x00} };  //9              
void setup()
{
  Serial.begin(9600);
  SPI.begin();
  pinMode(slaveSelect,OUTPUT);
  digitalWrite(slaveSelect,HIGH);
  sendCommand(shutDown,1);
  sendCommand(dispTest,0);
  sendCommand(intensity,1);
  sendCommand(scanLimit,7);
  sendCommand(decodeMode,0);
  for(i=0;i<8;i++)
    sendCommand(i+1,character[0][i]);
}   
void loop()
{
  if(Serial.available())
  {
    int ch=Serial.read();
    if(ch>='0' && ch<='9')
    {
      for(i=0;i<8;i++)
        sendCommand(i+1,character[ch-'0'][i]);
    }   
  }      
}
void sendCommand(byte command,byte value)
{
  digitalWrite(slaveSelect,LOW);
  SPI.transfer(command);
  SPI.transfer(value);
  digitalWrite(slaveSelect,HIGH);
}   

程式中只有定義第10接腳

但是輸出的 腳位  11和  13接腳 未定義，該如何從程式中加入程式碼讓它輸出會有 High 和 Low

求 Arduino 高手解答

感謝您的幫忙  因為上網找了一堆 可是不知道怎麼插入程式碼  非常感謝~~
