描述

用c语言写的一个时闹钟程序

单片机用16F877,主时钟用20MHz,用32768作定时时间。可以实现2路定闹,每一路都可分别设置和开关,采用4x4键盘,16x2的字符型LCD显示。连线在程序开头有说明。

程序的功能:

(1)上电后LCD背光打开,并显示倒计时5秒,然后时钟开始工作。

(2)用模式键(*)切换模式,如显示时间、日期、闹钟1、闹钟2等,并且可以用上、下键控制加1、减1或是闹钟的On、Off。

(3)原程序有16个键,包括0~9数字键,可以直接输入要设置的时间值,但后来将数字键取消了,你仍然可以通过修改程序的部分注释恢复此功能。

(4)闹钟有2路,时间到后闹2分钟,可按任意键取消本次闹钟。闹钟响时有2种音调,是用PIC的PWM实现的。

(5)按任意键可打开背光,1分钟后自动关闭背光。

(6)RA0~RA3为按键扫描输入,应接下拉电阻。

// Description:

// A timer program

// Ver 0.1: 2003-03-31, all cLOCk function with date display, 2 way alarm.

// Ver 0.2: 2003-05-05, (1) Alarm default is on,modify alarm1 time to 7:00:00,

// and alarm2 to 13:30:00.

// (2) Backlight will be enabLEDwhen alarming.

// (3) Automatic adjust day(28,30,31)。

// (4) Automatic move cursor to next location when set item.
