單片機驅動16*16點陣源程序(多種驅動方式)Proteus8.15仿真

ID:579397 · 發表于 2023-1-28 05:25

設計了四套驅動方案：1、154+595驅動 2、154+P口驅動 3、595驅動 4、單片機P口驅動
程序為文字左移顯示
供初學者參考

單片機16×16點陣（154+595驅動）源程序如下:

#include <intrins.h> //函數,應用于程序設計
#include <reg52.h> //單片機頭文件
/**********接口說明**********/
sbit SER=P3^0; //DS 第14腳串行數據輸入

sbit LATCH=P3^2; //ST_CP 第12腳輸出存儲器鎖存時鐘線
sbit OE=P3^3; //OE 第13腳輸出有效,低電平有效
