实现AD转换tlc549芯片的驱动，建模力量转化为数字量

实战四《简易四路抢答器》，程序文件名:"MCD-INTBUZ.ASM"，在8255单片机上实现-four real "Simple 4P Responder" program file name : "MCD- INTBUZ.ASM", in 8255 MCU to achieve

电子称 AD中文说明-dianzicheng yingwenshuoming

自制MP3硬盘播放器，含电路图（DDB）以，源代码及使用说明-Self-made hard drive MP3 players, including circuit diagrams (DDB) to, source code and use

这是一个键盘扫描的程序，相信想做毕业设计的同学非常想得到的哦，想要就看看吧，不好的话多提建议哦-This is a keyboard scanning procedures, wanted to believe that the students graduate design is the kind of oh, want to see it on, the poor more suggestions oh

我们设计的火灾报警器，基本上满足要求，大家可以参考-We design fire alarm, and basically meet the requirements of everyone can refer to

单片机电路图.开发者可借助此51电路原理图，大大简化开发难度，提高效率。-Single-chip circuitry. Developers can take advantage of the 51 circuit schematic diagram, greatly simplified the development of the difficulty and improve efficiency.

c51学习使用的资料 有100多个原程序-decoder learning to use the data more than 100 original program

51单片机P2口接4*4键盘的行线和列线；红灯亮时进行频率输入；绿灯亮时进行占空比输入；频率值暂定在100到60KHZ之间；输入频率和占空比时要输够六位整数，不够的在前面补0；占空比以百比数（0-100）形式存在。-51 Singlechip P2 mouth then 4* 4 keyboard line and column line red light when the frequency of input green when the input duty cycle frequency value is tentatively scheduled for between 100 to 60KHZ input frequency and duty than enough to lose six integers, not enough to fill in front of 0 duty cycle than a few hundred (0-100) form.

利用51单片机对u盘进行读写操作，其中用到的usb芯片是sl811master。-use 51 to u-SCM write, which to use the USB chip is sl811master.
