標題: 單片機控制16*16點陣顯示屏顯示字符，附仿真和源程序可運行
單片機控制16*16點陣顯示屏顯示字符，附仿真和源程序可運行。循環顯示想要顯示的字符。自己編寫，可運行。點陣可以在網上搜在線轉換的轉換成自己想要的字符放在源文件數組中，便可顯示。逐行，倒向，共陽極。

仿真原理圖如下（proteus仿真工程文件可到本帖附件中下載）


單片機源程序如下:
  1. #include<reg51.h>
  2. #define uchar unsigned char
  3. #define uint unsigned int
  4. #define out0 P0
  5. #define out1 P1
  6. #define out2 P2
  7. void delay(uint j){
  8. uchar i=250;
  9.         for(;j>0;j--){
  10.         while(--i);
  11.                 i=100;
  12.         }
  13. }

你好，我想問一下那個16*16的點陣是怎么連接的？
