As you have learnt that sleep( )/usleep()/nanosleep() are not good to delay a process. Timers can provide more accurate time control in applications. In this lab, you will explore POSIX timers and signal programming, experience the timer drift. The primary focus of this lab will be "time". The experiment will show you several methods to measure time in your applications.

程序详细功能介绍： * 利用AT89S51单片机的P0端口的P0.0－P0.7连接到一个共阳数码管的a－h的笔段上， * 数码管的公共端通过三极管8550选通。在数码管上循环显示0－9数字，显示时间的间隔可通过修改延时程序。 -Procedures detailed functional Introduction:* use AT89S51 MCU port P0 is connected to P0.0-P0.7 Yang a total digital control of the a-h T segment,* digital tube through the public side-gated transistor 8550. In the digital control on the circulation figures 0-9 show, indicating the time interval may be delayed by modifying the procedures.
