18f2423单片机内置12位AD,这是我自己调试过的18个例程.-18f2423 MCU built-in 12 AD, this is my own debugging routines ever 18.

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.

本例采用89C52, 晶振为11.0592MHZ，关于如何编制音乐代码, 其实十分简单,各位可以看以下代码.频率常数即音乐术语中的音调,而节拍常数即音乐术语中的多少拍 所以拿出谱子, 试探编吧!-Example use of the 89C52, crystal for 11.0592MHZ, on how to prepare music code, is actually very simple, you can see the following code. Frequency that is constant in terms of tonal music, and the constant beat of music terminology that is how much of the shoot so come up with music score , test made it!
