I2C communication was first introduced by Phillips. As said earlier it has two wires, these two wires will be connected across two devices. Here one device is called amasterand the other device is called asslave. Communication should and will always occur between two aMaster and a Slave. T...
The I2C-bus is for bi-directional, two-line communication between different ICs or modules. I2C (Inter Integrated Circuit,内部集成电路) 总线是价格低廉却很有效的用以互连小规模嵌入式系统内的外设的网络。I2C 总线用两根线来连接多支路总线中的多个设备。这种总线是双向、低速的,并... ...
