PIC16F877A, PIC16F877, PIC16F, C语言, 16F877A

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。
