通过数码管实现60S倒计时并蜂鸣器提醒,按键可以复位、暂停、增加减少。这一份代码也是通过C51自带的定时器完成,误差几乎可以忽略不计。
给别人弄的60S倒计时,数码管显示,需要的看看。#include#define uint unsigned int#define uchar unsigned charsbit P2_2 = P2^2;sbit P2_3 = P2^3;//sbit dula=P2^6;//sbit wela=P2^7;sbit beep=P1^4;sbit start_...
51单片机输入数字并数码管倒计时典型C语言代码使用STC89C52RC单片机,外接数码管、蜂鸣器。改代码非常适合初学者学习借鉴。#include#define uchar unsigned char#define uint unsigned intsbit dula=P0^0;sbit wela=...
以下是C语言实现数码管60S倒计时的示例代码: ```c #include #include #include #include // 数码管码表 const int digit[10][7] = { {1, 1, 1, 1, 1, 1, 0}, // 0 {0, 1, 1, 0, 0, 0, 0}, // 1 {1, 1, 0, ...
