51单片机的端口应用，绝对能用的，直接是开发板的程序，来下吧-51 port MCU applications, the absolute can be used, direct the development of board process to the next bar

实验箱上的蜂鸣器发出对应的音调（中音），当同时按下L和1-7时是，蜂鸣器发出低音，同时按下H和1-7时，蜂鸣器发高音。只要按键没松开，蜂鸣器一直发声，直到松到按键。-The buzzer sounded on the test box corresponding to tone (Tenor), when at the same time when you press the L and 1-7, the buzzer sounded a bass, while pressing the H, and 1-7 when the buzzer made treble. As long as no release button, buzzer sound has always been, until the pine to the button.

HD7279与51的驱动，主要修正了延时函数及按键函数，按键采集通过中断采集。-HD7279 51 and the driver, amended the delay function keys and function keys acquisition through acquisition interruption.

一个用于单片机仿真的好软件版。不需要花钱买仿真板，直接在电脑上用这个软件连接实物图就可以了。是电子设计的必备软件。里面还有教程！-A good simulation for the single-chip version of the software. The simulation does not need to spend money to buy plates, directly on your computer to use this software to connect the physical map on it. Electronic design is an essential software. There are tutorials there!

蜂鸣器响 改变蜂鸣器的频率，通过改变延时时间 蜂鸣器的时间要是是靠延时来完成的-Buzzer buzzer ring to change the frequency by changing the delay time if the buzzer is the time to be completed by the time delay

pid控制的源程序，很不错的，请大家注意关注啊-pid control source, it is good, draw attention to concerns ah
