1、将本文档拆分成 3 个文件：mian.c, all.h, key.cMian.c 文件包含：/*功能说明充电定时器，可以设置充电持续时间，充电时间等于预约时间时自动停止充电，再次按下充电键时继续充电。电路原理图缺省， 有需要请发邮件到 ，欢迎来信。按下充电键开始充电，充电灯闪烁，再次按下停止充电，在充电开始后不能进入设置状态。只有停止充电后方可进入。按下设置按键 1.5 秒后进入设置状态，充电灯熄灭，再次按设置键可以设置时间，相对应的时间灯亮，时间设置好后按下充电键退出设置，充电灯常亮。可设置的时间为 110 小时，在设置状态下 10 秒内无任何按键按下退出设置状态。晶振频率 22.1184M
