) 调整时间和日期,

只设置了四个按键

a, 复位按键;

b, 调整模态选择按键,切换调整不同参数;

c, 上调按键,调整模式下按此键被调整值上调;

d, 下调按键,调整模式下按此键被调整值下调.

这shi调整年份时de显示状态,LCD第二行末尾显示"yar".

依此类推,调整月份时显示"mth",调整日期时显示"day",小时时显示"hor",分钟时显示"min".

3) 软件部分.

程序中包含一个头文件"LCD1620.h",此文件中包含有关LCDde一些显示函数.

下面shi部分程序原代码---不知道怎么回事,今天网络速度比较慢,无法上传文件.如有需要可与我e-mail联系lhy_radio@.

/* 1,使用Atmega8内部RTC(实时时钟,32.768KHz) */

/* 2,显示使用LCD1620 */

/* 3,在Timer2中断中刷新显示，精度提高1S@5H */

/* 4,加入星期显示*/

/* 5,加入农历换算*/

/* 6,秒末位大于等于5时，显示公历：Solar 年月日*/

/* 7,SolarYear>2099或SolarYear<1900, */

/* 显示"Out of range!" */

/* 8,加入手动调整日期和时间*/
