STC89C58加18B20温度传感器构成的温度采集器程序-18B20 increases STC89C58 temperature sensor consisting of temperature acquisition program

汽车行驶记录仪的数据初始化组件，主要通过RS232串口或者USB口写数据到单片机，详细协议及数据格式参见国标的相关文件，该系统已经通过的国家公安部的标准检测-Vehicle Data Recorder initialization components, primarily through the RS232 serial or USB port to write data to the microcontroller, detailed agreement and data format See National Standard document, which has been adopted by the Ministry of National Standard Test

DS18B20.C(一般通用的数字温度传感器)完成代码,可直接使用.-DS18B20.C (general use digital temperature sensor) the completion code can be used directly.

本程序采用AT89C51单片机，ADC0809模数转换芯片进行模数转换，最终由数码管显示“0809**”。-This procedure using AT89C51 single-chip microcomputer, ADC0809 analog-to-digital conversion chip for analog-digital conversion, and ultimately by the digital tube displays

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.
