#M8废鼠标四位LED做多功能电子表

M8废鼠标四位LED做的多功能电子表<说明和源程序）<附上原理图）
做饭总是忘了时间，结果经常吃糊饭，就用M8、四位LED数码管和废鼠标做了个电子表。

1.BASCOM编程，有电子表、闹钟、倒计时闹响功能<煮饭时用这个功能，哈哈）
2.四位LED显示时间，蜂鸣器闹响
3.废鼠标做外壳，保留鼠标三个键做模式转换、时间、闹钟调整
4.因为接线少，没有做PCB板，用导线直接连线，用热溶胶固定、绝缘。

现在用的这个机器没装protel，没时间画电路图了，作个简单硬件说明：1、M8<1片），电阻8只<可选1-3k），四位7段led数码管1只<共阳），废鼠标1个，28IC座1个，电池1块，蜂鸣器1只 , 导线若干
2、portd口0-7顺序接led的A-G和DP，中间串8只电阻，led四个阳脚分别接portc口的1-4
3、portc.0接speaker；portb的0-2分别接鼠标中、左、右的微动开关，开关共地
4、我没有做pcb板，用热溶胶绝缘固定，防止短路。

几点说明：
1、使用内振，稳定性难以保证，若要高精度，建议用外振。

2、TCNT1的值可根据实验误差重新计算，此程序的是理论值。

3、LED数码管耗电较大，可选用lcd数码管
4、本来只想做个倒计时表放在厨房里，补来补去补成这个程序
5、程序由bascom-avr1.11.7.7编译通过，编译大小 5.14K
6、刚学单片机很短时间，错误和遗漏请批评指点，谢谢！
功能说明：
1、电子表、闹钟、倒计时闹响<以分钟为单位）
2、中键选择模式，切换电子表和倒计时
3、倒计时模式时，左键增加时间，右键减少时间，闹响时按键停止，重新倒计时，按中间键切换到电子表模式
4、电子表模式时，按先左后右键进入调整闹钟时间，小时闪烁，左加右减，按中间键切换到调整分钟，分钟闪烁，左加右减，再按中间键退出返回电子表模式
5、电子表模式时，按先右后左键进入调整时间状态，方法同上。
