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.

单片机应用＿＿交通灯程序报告，用汇编语言编写，注意程序在word中的逗号可能要改一下，才能在wave6000中用-SCM application procedures for traffic lights, using a compilation of language, attention to the procedures of the word may have to change a comma that can be used in wave6000

C51强大功能及其高效率的重要体现之一在于其丰富的可直接调用的库函数，多使用库函数使程序代码简单，结构清晰，易于调试和维护，下面介绍C51的库函数系统。-C51 powerful features and its high efficiency in one important manifestation of its rich can directly call the library, multi-use library functions to make the code simple, clear and easy to debug and maintenance, and C51 introduced below the library system.

这个两个rar文件是关于定时器0使用的例子, 也是我第一次使用定时器0做的实验程序: 1. T0_ASM.rar, (带中文注释的C51语言例程), 利用定时器0中断实现LED灯的简单控制。 2. T0_C51.rar, (带中文注释的51汇编语言例程), 利用定时器0中断实现LED灯的简单控制。 两个同样功能的timer0中断程序都在MCU51-63K仿真器下通过实验, 小虾们可以试试看。 -Rar files that are both about the example of the use of Timer 0 is also the first to use my timer 0 of the experimental procedure to do: 1. T0_ASM.rar, (with English language routines C51 annotated), make use of the timer 0 interrupt implementation easy control of LED lights. 2. T0_C51.rar, (with English Notes 51 assembly language routines), use of the timer 0 interrupt achieve easy control of LED lights. Same function in both programs at timer0 interrupted MCU51-63K emulator through the experiment, shrimp can give it a try.
