12864液晶显示器的测试程序，汇编语言的，很有价值的！-12864 test procedures for liquid crystal displays, assembly language, and great value!

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.
