C51语言的HD7279驱动程序-the HD7279 C51 Driver

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.

IIC 的驱动程序 很完整。通过KEIL C 编译在ROTUES 上用AT89C51仿真通过。-IIC driver complete. Through the KEIL C compiler ROTUES used in the simulation through the AT89C51.

时钟芯片DS1302的使用,用LED显示的，具有键盘调节功能,在Keil下测试通过-The use of clock chip DS1302 with LED display with a regulatory function of the keyboard, under the test adopted in Keil

这个是用DS1302的程序，也是用于车辆润滑系统的控制器，非常好用啊，非常好用哦-This is the procedure used DS1302 is also used in vehicle lubrication system controller, ah very useful, very easy to use, oh
