主要介绍一种基于Philips公司的MF RC500的射频识别读写器的设计：首先介绍系统的组成以及MF RC500的特性，接着给出天线的设计规范，最后给出MCU 89C52与MF RC500的接口原理图、对Mifare卡操作流程以及及读卡的程序。-Mainly based on the introduction of a Philips company MF RC500 RFID reader design: First of all system components as well as the introduction MF RC500 features, and then given antenna design specifications, and finally gives MCU 89C52 interface with the principle of MF RC500 diagram, the operation flow of the Mifare card and the card reader as well as procedures.

步进电机的单片机控制系统的设计用C语言编写的程序,可以直接使用-Stepper motor microcontroller control system design using C language program can be used directly

不同于一般形式的软件编程，嵌入式系统编程建立在特定的硬件平台上，势必要求其编程语言具备较强的硬件直接操作能力。无疑，汇编语言具备这样的特质。但是，由于汇编语言开发的复杂性，它并不是嵌入式系统开发的一般选择。而与之相比，C语言--一种"高级的低级"语言，则成为嵌入式系统开发的最佳选择。-Unlike most forms of software programming, embedded systems programming based on the specific hardware platform, is bound to require its programming language with a strong ability to direct hardware. Undoubtedly, the compilation of language with such qualities. However, the assembly language development complexity, it is not embedded systems development in general choice. But compared with C language-- a "senior vulgar" language, embedded systems development as the best option.
