MSP430单片机综合实例（proteus） [复制链接]

最近学了一段时间的msp430单片机，感觉这款低功耗的单片机很有意思，虽然还没有彻底弄明白它的具体操作，但是一些简单的程序已经能够实现了，下面是我写的一个MSP430比较综合一点的程序，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;

const uchar table2[]="0123456789";
const uchar table3[]="   15:45:00  ";
void delay2(uint x)
{

 while(x--)
  for(y=120;y>0;y--);
}
void w_com(uchar com)

    rs_0;
    P2OUT=com;
    delay2(1);

}
void keyscan2()

    if(P1IN==0xfe)
    {
        delay2(1);
        while(P1IN==0xfe);
        count2++;

          count2=0;
        temp1=count2/10;

        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()
