1、学习定时器T1溢出中断的使用
2、学习电脑时钟的编程方法
3、在程序运行时按SHIFT进行校时
使用注意：
1、应包含头文件slavr.h
2、在工程选项中的Additional Lib中填入slavr 使用编译器使用附加库文件

电子时钟功能与使用
该电子钟由于使用12MHZ晶振，故而能获得较高精度的时间。它能同时显小时，分钟和秒。设有两个按键：A和B键。A键用于选择要校正的目标，是小时，分钟还是秒，按第一下时，选择秒，按第二下则选分钟，第三下则选小时，第四下则退出校时，第五下又选秒，如此循环，可选择校时或退出校时。B键每按一次，所选对象就会加1，比如，已选择分钟，那么每按一下此键，分钟数目就会加上1。
Electronic clock function and the use of the bell as a result of the use of e-12MHZ crystal, they are able to obtain a higher accuracy of the time. At the same time it can significantly hours, minutes and seconds. There are two buttons: A and B keys. A key is used to select the goal of correction is hours, minutes or seconds, the next by the first, the choice of seconds, according to the election under the second minute, the third hour of the election, has withdrawn from school under the fourth, the fifth another election under the second, and so the cycle of school or may choose to withdraw from school. B button every time, the selected object will be plus 1, for example, have chosen to minutes, then each click on this button will add the number of 1 minute. (2009-06-11, Asm, 56KB, 下载26次)

1参考电压需要足够精确,推荐使用外部高精准参考电压.
2如果PGA可调,增益系数一般是越小噪声越低.
3一般最好用到满量程,此时AD精度不浪费.
4如果有偏置,需要进行自校.
5请注意在使用DEMO板调试时,会由调试口导入PC噪声,由信号连接线导入外部噪声,因此建议使用屏蔽电缆传输信号.
A sufficiently accurate reference voltage needs to recommend the use of an external high-precision reference voltage. 2 If the PGA adjustable gain coefficient the smaller the noise is generally lower. 3 generally best to use full-scale, precision is not a waste of time AD. 4 If there is bias, since the need for school. 5 Please note that the use of DEMO board debugging, the debug port to import from PC noise, by the signal cable into the external noise, it is proposed the use of shielded cable transmission signal.

数字电子钟是一种精确的计时工具，它精确显示秒、分、时，是一种比传统机械表更灵活方便的钟表。还可附加闹铃，报时等功能。因而在日常生活的各种领域应用广泛。数字电子钟由秒信号发生器、“时、分、秒”计数器，译码器及显示器，校时电路组成。秒信号发生器是整个系统的时基信号，作为秒脉冲送入计数器，计数结果通过“时、分、秒”译码器显示时间
Digital electric clock is an exact timing tool, it is precisely that, when, is a more flexible than the traditional mechanical clocks convenience. Still can add alarm, time, etc. Therefore in the daily life of various fields.
