Description: 基于DTMF制式的来电显示设计（暂时不支持FSK模式）
以下硬件组成：
MCU：51内核各系列单片机
DTMF双音频信号解码芯片：MT8870
显示：带中文字库的128*64点阵形液晶模块
（注：MCU使用12M晶振，以本C51程序的算法，编译后，程序约占用2K字节，
电话本每组约占用20~40字节，每组信息包括电话号码，姓名，单位）

Description: 这个源代码是关于MCS-51的无线接收，用89S52控制MT8870B进行DTMF解码。程序相当的经典，本人调试了几周后，达到了非常好的效果。误码率相当的小。我觉得好东西要大家分享的，所以今天我上传此代码，与大家共同分析进步。-the source code is on the MCS-51 wireless receiver, S52 control with 89 MT8870B for DTMF decoder. Quite the classic procedure, I debug a few weeks later, to achieve very good results. The error rate is very small. I think that good things should be shared, so I upload this code, and the analysis of common progress.
