The paper converses the two protocols in detail and a SPI to I2C Bridge.These two are commonly used serial data transfer protocol in embedded system.I2c is having advantages on few issues in comparison to SPI. The most important advantage of I2C is less number of pins and signals require. ...
I2C (Inter Integrated Circuit) also known as TWI (Two wire Interface) is a bus interface connection that is used in many devices such as Sensors, RTC and EEPROM. Unlike SPI this protocol only uses two wires to establish the connection and hence known as Two wire interface. This protocol ...

In an I2C bus network, all the slave devices connected to the I2C bus should have a unique address to be communicated by the master device. In the I2C protocol, no provision is provided for successful communication if two slave devices having the same address are connected to the I2C bus....
