MSP430單片機綜合實例（proteus）

/*轉自本人新浪博中的記錄，時間：2010-09-26 16:28:06

最近學了一段時間的msp430單片機，感覺這款低功耗的單片機很有意思，雖然還沒有徹底弄明白它的具體操作，但是一些簡單的程序已經能夠實現了，下面是我寫的一個MSP430比較綜合一點的程序，和大家分享一下；

主程序：

#include<msp430x24x.h>
#include"liushui.h"
#include"juzhen.h"
#define uchar unsigned char
#define uint  unsigned int
#define rs_0  P6OUT&=~BIT4;
#define rs_1  P6OUT|=BIT4;
#define rw_0  P6OUT&=~BIT5;
#define rw_1  P6OUT|=BIT5;
#define e_0   P6OUT&=~BIT6
#define e_1   P6OUT|=BIT6;
#define wei1_0 P6OUT&=~BIT0;
#define wei1_1 P6OUT|=BIT0;
#define wei2_1 P6OUT|=BIT1;
#define wei3_0 P6OUT&=~BIT2;
#define wei3_1 P6OUT|=BIT2;
#define wei4_0 P6OUT&=~BIT3;
#define wei4_1 P6OUT|=BIT3;
uint j,t,count1,count2,count3,count4=99;
uchar temp1,temp2;
const uchar table1[]={" shizhong dabao "};
const uchar table2[]="0123456789";
const uchar table3[]="   15:45:00  ";
void delay2(uint x)
{
 uint y;
 while(x--)
  for(y=120;y>0;y--);
}
void w_com(uchar com)
{
    rs_0;
    P2OUT=com;
    delay2(1);
    e_1;
    e_0;
}
void w_dat(uchar dat)
{
    rs_1;
    P2OUT=dat;
    delay2(1);
    e_1;
    e_0;
}
void init_1602()

  w_com(0x38);
  w_com(0x0c);
  w_com(0x06);
  w_com(0x01);
  w_com(0x80);
}
void keyscan2()
{
    if(P1IN==0xfe)
    {
        delay2(1);
        while(P1IN==0xfe);
        count2++;
        if(count2==60)
          count2=0;
        temp1=count2/10;
        temp2=count2; 
        w_com(0x86+0x40);
        w_dat(table2[temp1]);
        delay2(5);
        w_com(0x87+0x40);
        w_dat(table2[temp2]);
    }
    if(P1IN==0xfd)
    {
       delay2(1);
       while(P1IN==0xfd);
       count3++;
       if(count3==24)
         count3=0;
       temp1=count3/10;
       temp2=count3;
       w_com(0x83+0x40);
       w_dat(table2[temp1]);
       delay2(5);
       w_com(0x84+0x40);
       w_dat(table2[temp2]);
    }
}
void shuma()
{
    temp1=count4/10;
    temp2=count4;
    wei1_0;
    P5OUT=count5;
    delay2(1);
