在没有专用总线主机(如DS2480B、DS2482)的情况下，微处理器可以轻松地产生1-Wire时序信号。本应用笔记给出了一个采用‘C’语言编写、支持标准速率的1-Wire主机通信基本子程序实例。1-Wire总线的四个基本操作是：复位、写“1”、写“0”和读数据位。字节操作可以通过反复调用位操作实现，本文提供了通过各种传输线与1-Wire器件进行可靠通信的时间参数-In case no dedicated bus host (such as DS2480B, DS2482), the microprocessor can easily generate 1-Wire timing signal. This application note gives a ' C'　language supports the standard rate, 1-Wire host communication routines. 1-Wire bus four basic operations: reset, write " 1" , write " 0"　and read data bits. The byte operation can be achieved by repeatedly invoked bit operating to provide a reliable communication through various transmission line and 1-Wire device parameters
