系统能够产生正弦波、方波、三角波。同时还可以作为频率计测频率。函数信号的产生由MAX038和外围电路完成，能产生1Hz―20MHz的波形。-system can produce sine, square, triangle wave. Also as frequency measurement frequency. Signals generated by the MAX038 completed and the external circuit, which can produce 1Hz- 20MHz waveforms.

单片机与PC机串口通讯测试程序，波特率9600bit/s，液晶1602显示PC机回发的字符-Single-chip serial communication with the PC-test procedure, the baud rate 9600bit/s, LCD PC machine back to 1602 show that fat characters

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.
