WebI2C is a broadcast topology network, like Ethernet. Any node may connect to any other node in the network. Each node is a device, such as a microprocessor like the Atmel 89C55 (aka the 8051). Unlike Ethernet, the bus is controlled in a master/slave connection. Any node may gain control of a free bus and become the master of the bus. WebI 2 C is appropriate for peripherals where simplicity and low manufacturing cost are more important than speed. Common applications of the I 2 C bus are: .
