1、程序
#include "reg52.h"typedef unsigned int uint16; //对系统默认数据类型进行重定义typedef unsigned char uint8;#define SMG_A_DP_PORT P0 //应用宏定义数码管段码口//共阴极数码管显示0~F的段码数据uint8 gsmg_code[16]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07, 0x7f,0x6f,0x77,0x7c,0x39,0x5e,0x79,0x71};void main(){ SMG_A_DP_PORT=gsmg_code[15];//将数组第1个数据赋值给数码管段选口 // 0-9对应0-9 10-15对应a-f while(1) { } }
