功能说明:

1.六位数码管动态扫描显示时间（格式为：HHMMSS，24小时制）。

2.时钟信号由单片机内部定时器硬件单元编程产生。



本实战的目的是让大家进一步熟悉定时器的编程，多位数码管动态扫描显示的编程。

-Function:　six digital tube dynamic scan time (format: HHMMSS, 24-hour clock).　 2 clock signal generated by the microcontroller internal timer hardware unit programming.　 The real purpose of further familiar with the programming of the timer, the programming of many digital tube dynamic scan display.
