求大神指教啊，多谢了
感觉程序有点乱；主要在于
uchar LCD_Line_1[] = {"L1: ,R1: kp"};
uchar LCD_Line_2[] = {"L2: ,R2: kp"};
void main()
{
uint i;
uint d1;
uint d2;
uint d3;
uint d4;
LCD_Initialise();
DelayMS(10);
while(1)
{
d1=Get_AD_Result1()*200/255;
d2=Get_AD_Result2()*200/255;
d3=Get_AD_Result3()*200/255;
d4=Get_AD_Result4()*200/255;
LCD_Line_1[3]=(d1/100+'0');
LCD_Line_1[4]=(d1/10%10+'0');
LCD_Line_1[5]=d1%10+'0';
LCD_Line_1[10]=(d2/100+'0');
LCD_Line_1[11]=(d2/10%10+'0');
LCD_Line_1[12]=d2%10+'0';
LCD_Line_2[3]=(d3/100+'0');
LCD_Line_2[4]=(d3/10%10+'0');
LCD_Line_2[5]=d3%10+'0';
LCD_Line_2[10]=(d4/100+'0');
LCD_Line_2[11]=(d4/10%10+'0');
LCD_Line_2[12]=d4%10+'0';
Set_Disp_Pos(0x00);
i=0;
while(LCD_Line_1！='\0')
LCD_Write_Data(LCD_Line_1[i++]);
Set_Disp_Pos(0x40);
i=0;
while(LCD_Line_2！='\0')
LCD_Write_Data(LCD_Line_2[i++]);
}
}
Get_AD_Result1()之类的为传感器返回值，
就是不知道为什么lcd1602上第二列的数据都是0

IO口重复了啊！
把其改为不同IO口，再连一连电路就OK啦！
我是把那四个mpx传感器都接同样的时钟信号和使能信号的，所以有些接口是一样的，但是输出口是不同的，而且那个能够显示两路数据出来也证明应该不是这个的问题，感觉还是显示器的设置不对。
把下面3处改了应该就可以了吧！
dat12=dat12<<1|DIO1; 改为dat12=dat12<<1|DIO2;
CLK4=0; DIO1=0; _nop_();_nop_(); 改为CLK4=0; DIO4=0; _nop_();_nop_();
CLK4=1; DIO1=1; _nop_();_nop_(); 改为CLK4=1; DIO4=1; _nop_();_nop_();
真是太谢谢你了，就是你说的这样的，这几天做毕设头一次学这个，好多不懂，这个问题都困扰了我好久了，你真是帮了我的大忙了。
