I2C, or Inter-Integrated Circuit, is a chip-to-chip interface supporting two-wire communication. You can connect to I2C peripheral devices and read from and write to them. Create the interface object using thedevicefunction with anaardvarkorni845xobject. ...
I2C Specification:I2C规范或集成电路互连规范。I2C Communication Interface:I2C通信接口或集成电路互连通信接口。I2C Communication Protocol:I2C通信协议或集成电路互连通信协议。I2C:在无法书写上标数字“2”时,可书写为“IIC”或“I2C”。二. 什么是总线(Bus)2.1 计算机中Bus术语的来源 早期的计算机体积庞大,连...

1-wire,即单线总线,又叫单总线。 IIC Communication I2C总线是PHLIPS公司推出的一种串行总线,它只有两根双向信号线。一根是数据线SDA(serial data I/O),另一根是时钟线SCL(serial clock)。 如下图所示,IIC总线上可以挂多个器件,而每个器件都有唯一的地址,这样可以标识通信目标。数据的通信的方式采用主从方式,主机...
At any given time only the master will be able to initiate the communication. Since there is more than one slave in the bus, the master has to refer to each slave using a different address. When addressed only the slave with that particular address will reply back with the information whil...
I2C Communication Although I2C uses only two communications lines (clock and data), it can accommodate multiple devices on the same I2C bus; this is accomplished by making use of an addressing scheme where each device on the bus has a unique address. Communication starts with sending out the ...
Inter-Integrated Circuit (I2C) is also referred to as Two-Wire Interface (TWI). In I2C communication there is a master device and one or more slave devices. The microcontroller can be configured as either a master or slave device. The clock (SCL) signal
I2C Communications (Wire) This is an I2C communications library that facilitates two-wire class communications with I2C/TWI devices (also called "Wire Library"). The pull-up to communication lines are needed. To use, specify#include <wire.h>. ...

The I2C deadlock problem cannot be fundamentally avoided. In addition to the I2C deadlock caused by the abnormal reset of the MCU, the slave device may also pull down the SDA abnormally to cause the deadlock during the normal communication process. Therefore, the software should be designed to...
