WebbWorking of I2C protocol. I2C is a simple chip-to-chip communication protocol. In I2C, communication is always started by the master. When the master wants to communicate with the slave then it asserts a start bit followed by the slave address with read/write bit. After the asserting of the start bit, all slave comes in the attentive mode. WebbFigure 1: Generalized I 2 C Connection Diagram. The I 2 C bus can support multiple devices, both SLAVE and MASTER, and the only limitation is the capacitance on the bus (400pF) and the address space (128 unique addresses) as more devices are added..
