超炫幻彩跑马灯

視頻：http://v.eepw.com.cn/video/play/id/1935



用RL78/G13 开发板做的超炫幻彩跑马灯，可以随意调整模式，速度，颜色

用了八個RGB三色共陽LED
R LED連接到P2
G LED連接到P1
B LED連接到P7

三個接鍵連接到P00/P01/P02 用于選擇模式/顏色/速度/亮度

視頻正在上傳中，稍候登場





程序如下：

定義以下文件頭：
#define KeyPort           P0

#define NoKeyData         0x07
#define Key1Data          0x06
#define Key2Data          0x05
#define Key3Data          0x03
#define Key12Data         0x04
#define MODE_STEP         300
#define RedLedPort        P2
#define GreenLedPort      P1
#define BlueLedPort       P7

#define MAX_LED_MODE                      10
#define LED_OFF                           0xff
#define MAX_COLOUR_MODE                   8
#define MAX_SPEED                         500
#define MIN_SPEED                         5000
#define FLASH_SPEED_STEP                  300
#define MAX_BRIGHTNESS_RATE               5


定議以下寄存器：
unsigned char LedTimerCount;
unsigned char LedOnCount;
unsigned int LedStepCount;
unsigned char Direction=0;
unsigned char LedMode;
unsigned char ColourMode;
unsigned char RedLedOnCount;
unsigned char GreenLedOnCount;
unsigned char BlueLedOnCount;
unsigned char RedPortData;
unsigned char GreenPortData;
unsigned char BluePortData;
unsigned short FLashSpeed;
unsigned char BrightnessRate;

unsigned char KeySave;
unsigned char KeyBuffer;

/***************config RGB colour*************/
const unsigned char RGBData[MAX_COLOUR_MODE][3]=
{
  100,0,0,
  80,50,10,
  90,80,0,
  10,100,0,
  0,0,100,
  10,100,20,
  100,40,70,
  100,100,100
};


LED上電初始化程序：

/******setup default mode***********/
void SetupLed(void)
{
    ADPC=0x01;
    PU7=0xff;
    PM7=0x00;
    PU1=0xff;
    PM1=0x00;
    PM2=0x00;
    RedLedPort=LED_OFF;                 //set red off
    GreenLedPort=LED_OFF;               //set green off
    BlueLedPort=LED_OFF;                //set blueoff
    LedMode=0;                          //set default led mode
    ColourMode=1;                       //set default led colour
    RedPortData=0x80;                   //set default red led status
    GreenPortData=0x80;                 //set default green led status
    BluePortData=0x80;                  //set default blue led status
    FLashSpeed=2000;                    //set default flash speed
    BrightnessRate=2;                   //set default led brightness rate
}

  //unsigned char Temp;
  TMIF00 = 0U;
