Like SPI, I2C is synchronous, so the output of bits is synchronized to the sampling of bits by a clock signal shared between the master and the slave. TECH, EEE, NIT BHOPAL E-mail: [email protected] I2C devices have open drain outputs therefore, a pull-up resistors must be connected to the I2C bus line with a voltage source.

Both I2C Master and I2C Slave are supported. Create the interface object using the i2c function, and use the fread and fwrite functions for communication. I2C is a multi-master and multi-slave bus. Some microcontrollers even feature hardware to implement the I2C protocol. Serial Bus Overview. I2C Communication with SMI Protocol-A 1.
