单片机编程 PCA9547 8 channel I2C bus mult
The PCA9547 is an octal bidirectional translating multiplexer controlled by the I2C-bus.The SCL/SDA upstream pair fans out to eight downstream pairs, or channels. Only oneSCx/SDx channel can be selected at a time, determined by the contents of theprogrammable control register. The device powers up w ...

The PCA9548A is an octal bidirectional translating switch controlled via the I2C-bus. TheSCL/SDA upstream pair fans out to eight downstream pairs, or channels. Any individualSCx/SDx channel or combination of channels can be selected, determined by thecontents of the programmable control register.An ...
单片机编程 PCA954X家庭的I C SMBus多路复用器与开关
The Philips family of Multiplexers and Switches consists of bi-directional translating switches controlled via the I2C or SMBus to fan out an upstream SCL/SDA pair to 2, 4 or 8 downstream channels of SCx/SDx pairs. The Multiplexers allow only one downstream channel to be selected at a time, while th ...
通信网络 双绞线的基本知识
双绞线(TP:Twisted Pairwire)是综合布线工程中最常用的一种传输介质。双绞线由两根具有绝缘保护层的铜导线组成。把两根绝缘的铜导线按一定密度互相绞在一起,可降低信号干扰的程度,每一根导线在传输中辐射的电波会被另一根线上发出的电波抵消。双绞线一般由两根22～26号绝缘铜导线相互缠绕而成。如果把一对或多对双绞线放在 ...

The Linux Enterprise Cluster explains how to take a number of inexpensive computers with limited resources, place them on a normal computer network, and install free software so that the computers act together like one powerful server. This makes it possible to build a very inexpensive and reliable ...
