51单片机程序——数码管显示0~99
加入技术交流群
#define DataPort P0
//定义数据端口 程序中遇到DataPort 则用P0 替换
#define CtrlPort P1
//定义控制端口
unsigned char code DuanMa[10]={0xc0,0xf9,0xa4,0xb0, 0x99,0x92,0x82,0xf8,0x80,0x90};// 显示段码值0~9
unsigned char code WeiMa[]={0x01,0x02,0x04,0x08,0x10,0x20,0x40,0x80};//分别对应相应的数码管点亮,即位码
unsigned char TempData[8];
//存储显示值的
全局变量
void Delay(unsigned int t); //函数声明
