通過(guò)調(diào)整可調(diào)變阻器，LCD上顯示相應(yīng)電壓值。
仿真原理圖如下（proteus仿真工程文件可到本帖附件中下載）


單片機(jī)源程序如下:
  1. #include <reg51.h>
  2. #include <stdio.h>
  3. #include <intrins.h>
  4. #define uchar unsigned char
  5. #define uint unsigned int
  6. #define DATA P2   //數(shù)據(jù)端口

  8. sbit start = P3^0;   //
  9. sbit EOC = P3^1;
  10. sbit OE = P3^4;

  12. sbit RS = P3^7;    //指令數(shù)據(jù)選擇
  13. sbit E = P3^5;    //指令數(shù)據(jù)控制
  14. sbit RW = P3^6;    //讀寫(xiě)控制
  15. sbit busy = P2^7;   //忙標(biāo)志
  16. sbit CS1 = P3^2;   //左屏幕選擇，低電平有效
  17. sbit CS2 = P3^3;   //右屏幕選擇
  18. sbit LED = P0^1;
