這是在做傳感器實驗顯示的時候的副產物，可以顯示放在字庫文字，數字可以放在一個數組如uchar code xue[]={5,2,0,0,1,3,1,4,};不用在數字庫里面排序，優化了顯示代碼。顯示時可以不用分上下部分
單片機源程序如下:
- #include <intrins.h>
- #include <reg51.h>
- #define uchar unsigned char
- #define uint unsigned int
- #define LCD_DATA P0
- sbit E1=P2^4;
- sbit E2=P2^5;
- sbit A0=P2^7;
- sbit RW=P2^6;
- uchar code xue[]={5,2,0,0,1,3,1,4,};
- uchar code ziku[]=
- {
