C51入门大全,对初学者很有帮助,认真学习一下里面的程序或者直接拿出来在单片机上运行一下,里面的程序基本上都是有效的.-C51 Portal Daquan, very useful for beginners. seriously study the inside of the program or directly out of the running on this MCU, Basically, the procedures which are effective.

一个采用C8051F020+CH372实现的带USB功能的流量测控系统，包括C8051F020的AD/DA/串口编程、触摸屏的串口编程、CH372实现的USB接口编程（原创）等。这些源代码已在某产品中使用。-A used C8051F020+ CH372 achieved with USB function of flow measurement and control system, including the C8051F020 the AD/DA/serial programming, the serial touch-screen programming, CH372 realized USB Interface Programming (original) and so on. These source code has been used in a product.

利用PWM实现正弦波和DTMF-achieve sine wave PWM and DTMF

基于C51单片机的多机串口,MODBUS协议通讯的实现方法.-C51 Microcontroller Based Multi-machine serial port, MODBUS communication protocol implementations.

液晶显示器（LCD液晶显示面板）和LCD模块（LCM液晶显示模块）的开发与设计

这个是液晶模块1602A用于单片机AT89S52的C语言驱动头文件.这个头文件不是普通的头文件，笔者在其中加进了很多自己的东西。而且经过自己的实际验证是可以用的。 　　有了该文件，你可以不用看1602的DATASHEET就会使用。-This is a LCD module 1602A for the single-chip AT89S52 the C language driver header file. This header file is not an ordinary header files, in which the author added a lot of our own things. But after their own actual authentication can be used. With the file, you can not watch the 1602 will be used DATASHEET.

利用ps2键盘向单片机输入数据，这样做不仅可以减少输入输出口，而且程序代码短小精悍，可以极大的提高单片机的执行效率．-Ps2 keyboard to use single-chip input data, to do so not only can reduce the input and output port, and program code dapper, you can greatly improve efficiency in the implementation of SCM.

本例中含有电路图及程序，单片机的仿真也含其中，很有用哦-In this case contains circuitry and procedures, including single-chip microcomputer in which the simulation is also useful Oh! !

51单片机浮点子程序库(小),直接嵌入,方便使用.-51 single-chip floating-point subroutine library (small), directly embedded, user-friendly.
