Description: 使用AVR单片机 codevision C语言实现的pt2272解码。目前网络上类似代码基本上是使用51系列单片机加汇编语言完成的，可移植性比较差。-codevision AVR using C language pt2272 the decoder. Currently the network code is basically similar to the use of 51 series microcontroller plus the completion of assembly language, portability are relatively poor.

Description: 单工无线呼叫系统分发射和接收两大部分。发射部分采用锁相环式频率合成器技术， MC145152和MC12022芯片组成锁相环，将载波频率精确锁定在35MHz，输出载波的稳定度达到4×10-5，准确度达到3×10-5，由变容二极管V149和集成压控振荡器芯片MC1648实现对载波的调频调制；末级功放选用三极管2SC1970，使其工作在丙类放大状态，提高了放大器的效率，输出功率达到设计要求。接收部分以超大规模AM/FM立体声收音集成芯片CXA1238S为主体，灵敏度、镜像抑制、信噪比等各项性能指标均达到设计要求；音频功率放大器采用集成芯片LM386，电压放大倍数最大为200。采用PT2262/2272编码/解码电路实现了数据传输业务以及对台号的选择等功能；音频输入和数据输入可自动转换；AT89S52作为整个系统的控制部分，程序设计采用C语言在KEIL51的编译器上编程实现；显示采用128×64点阵型液晶显示。经测试，整机功能齐全，各项性能指标符合系统要求，接收波形稳定，无明显失真。-The simplex wireless-calling system consists of two parts: transmit part and receive part.The transmit part adopts the phase-locked loop pattern of frequency synthesizing technology and uses the MC145152 and MC12022 chips to compose the phase-locked loop.It locks the frequency of the carrier-wave at 35MHz.The stabilization of the carrier-wave can be 4×10-5,the accuracy can be 3×10-5.The frequency modulation and the confection of the carrier-wave are realized by the capacity-changing diode V149 and the integration voltage-control oscillator MC1648 chip.The end power amplifier uses the audion 2SC1970 to make it work in the third magnifying state,it improves the efficiency of the magnifier and the power of the output reaches the design demand.The receive part uses the super cosmically AM/FM dimensional sound stereo radio reception integration chip CXA1238S as the main part.The sensitivity、the mirror-control restrain、the SNR and every capability index all reach the design demand.The audio
