单片机用T1中断在IO口P1.0输出乐曲(在P1.0口与VCC间接一喇叭即可听到) 1.由于输出的是方波，比较难听:-)你也可以将波形细分用DA输出正弦波 2.由于T1频繁中断，任何其他中断发生都会是乐曲打顿，只适合试验 3.优化音符编码：一个字节中包含节拍、音符、升降调，可区分数据和命令 -Single-chip microcomputer used in the IO port T1 interrupt output music P1.0 (P1.0 port with VCC in the indirect one can hear the speaker) 1. As the output is a square wave, more bluntly :-) You can also fine-waveform DA output sine wave with sub-2. Due to the frequent interruption of T1, any other interruption occurs Dayton will be playing music, is only suitable for test 3. optimized coding notes: A byte contains rhythms, notes, take-off and landing tune can distinguish between data and command

拷拷贝到你的Keil安装目录下的c51in文件夹中。 工程文件中需设置一下: project->Option for Target Target1 选Debug页 左侧最下面 Dialog Dll 一般是DP51.DLL，不用修改 Parameter 中是 -P51 在其后加入 -dledkey 即该行看起来应该是这样的： -p51 -dledkey 保存即可 进入调试后，点击：Peripherals，其中多出一个“键盘LED实验仿真板”选择该项即可。-emboss your copy of the Keil installation directory under the decoder bin folder. The project document to be provided as follows : project-gt; Option for Target Target1 election Debug bottom of the left page is generally Dialog Dll DP51.DLL, need not be amended Parameter is- P51 add after-dledkey that the bank should look like this :-p51-can be preserved into dledkey to debug and click : Peripherals, in which more than a "keyboard LED simulation board," which can be chosen.

这是用单片机实现的多功能数字钟,通过8255扩展端口,AD0809将模拟信号转换成数字信号进行处理,可以比较精确的测出电压值.-This is the MCU multifunction digital clock, through the 8255 expansion port, AD0809 a conversion of analog signals into digital signal processing, more precise measuring the voltage values.

在单片机应用设计中，4*4键盘是经常用到的，在这个程序种，提供了驱动键盘的基本函数，用户可以直接调用，可以很容易的移植到你的系统上。程序中并附带了，lcd1602的驱动程序-Application in the design of single-chip, 4* 4 keyboard is frequently used in the process of providing the basic function-driven keyboard, users can directly call, can be easily ported to your system. And incidental to the proceedings, lcd1602 driver
