1-Wire®网络可靠设计指南

1-Wire协议设计的初衷是为相邻器件的短距离连接提供一种便利的通信方式，1-Wire还提供了一种通过微处理器单个端口增加辅助存储器的途径。在以后的应用中，1-Wire协议被扩展到网络系统，通信范围超出了电路板尺寸。本文从多个方面讨论了保证1-Wire网络可靠运行的设计指南。附录中说明了精确调整1-Wire总线接口的方法，并列举了不同条件下的1-Wire通信波形。

Guidelines for Reliable Long Line 1-Wire Networks


Abstract: The 1-Wire protocol was originally designed to facilitate communication with nearby devices on a
short connection. 1-Wire was also a way to add auxiliary memory on a single microprocessor port pin. Methods
were later developed to extend the 1-Wire protocol to network applications well beyond the size of a circuit
board. This document discusses various aspects of 1-Wire networks and provides design guidelines for their
reliable operation. Several appendices address fine-tuning the 1-Wire bus interface and illustrate 1-Wire
