The PCF7991AT is a fully integrated Advanced Basestation IC, ABIC, designed for car immobilizer systems providing read and write access to an identification transponder. The device is intended for use with the NXP transponder family (PCF79xx) as well as other transponder types operating at 125 kHz and employing ASK, Amplitude Shift Keying for write and AM/PM for the read operation. The receiver characteristics (amplifier gain,filter cutoff frequencies) can be optimized to system and transponder requirements. The PCF7991AT IC is designed for easy integration into immobilizer read/write and read-only systems featuring a high degree of integration and very low external component count. The device integrates a powerful antenna driver/modulator, a low-noise adaptive sampling time demodulator, programmable filters/amplifier and digitizer, required to design high-performance basestations. A three wire microcontroller interface is provided for programming the PCF7991AT as well as for th

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.

PIC18F4550+18B20测温程序本程序实现： 1、使用DS18B20数字温度传感器测温（通过RE1端口），小数点后2位。 2、使用LCD1602通用液晶显示屏显示：Temp=26.32摄氏度 3、完全调试通过。
