ia4421 芯片用于实现800米无线通讯-IA4421 IS WERALESS CHIP

485通信在工业控制及管理系统中应用非常广泛，但485总线的相关资料教材上说明的却非常泛泛，这些资料对485通讯做了详细介绍，并有应用案列，相信对朋友们很实用-485 Communication in industrial control and management system is widely used, but the 485 bus information materials on the description is very general, such information on the 485 made a detailed presentation and have applied the case of columns, I believe that friends are very practical for

功能：实现对DS18B20的读取 原理：单总线协议 注意：单总线协议对延时要求比较严格，此程序中采用的是11.0592M的晶振，如果使用其他的晶振请跟据DS18B20的资料修改延时参数-functions : to achieve DS18B20 read Principle : single-bus protocol attention : single-bus protocol to delay requirements more stringent, this procedure is used in the crystal 11.0592M if the use of other crystal please According to the information DS18B20 delay parameter changes

仿真步骤如下： 1、把3个帖子的内容分别保存为51t9py.c,51t9py_indexa.h,5py_mb.h，放在同一目录下，将51t9py.c加入工程编译 2、由于Keil的模拟串口是单字节显示，汉字显示为乱码，所以要加挂RICHWIN或RichView这种会重新刷新显示的中文平台，或手工刷新屏幕，所以请先到 http://www.pchome.net/dl/chinese.htm 下载RichView，安装运行 3、在Keil环境下可以直接按“Ctrl＋F5”键仿真，按“F5”全速运行，切换到在串口依次输入: // 64*.6 426***.5 98*.7 936.3 586.1 4826*.1 9464*.7 64*.6试试:-) 4、按键对应(根据我自己的手机设置的,全部在PC的小键盘操作)： -simulation steps are as follows : 1 and 3 respectively, the content of messages posted on the preservation of 51t9py.c, 51t9py_indexa.h, 5py_mb.h, on the same directory, will join the project 51t9py.c compiler 2, Keil is the simulation of single-byte Serial show , the Chinese showed gibberish, so need to add or RichView RICHWIN this show will re-set the Chinese platform, or manual refresh screen, so please download RichView http://www.pchome.net/dl/chinese.htm to install three operations in Central Keil Habitat can be directly "Ctrl+ F5" key simulation, according to the "F5" running full-speed, switched to the ser
