Host adapters See more I C is the basis for the ACCESS.bus, the VESA Display Data Channel (DDC) interface, the System Management Bus (SMBus), See more WebI2C Bus consists of only two wires and is named serial data line ( SDA) and a serial clock line ( SCL ). At the physical layer, both SCL and SDA lines are of the open-drain design, thus pull-up resistors are needed.
WebThe GPIO based I2C bus master driver can be configured to provide fault injection capabilities. It is then meant to be connected to another I2C bus which is driven by the I2C bus master driver under test. The GPIO fault injection driver can create special states on the bus which the other I2C bus master driver should handle gracefully. WebThese two wires are Serial clock line or SCL and Serial data line or SDA. Masters and Slaves play important role in I2C communication. Master is the one which initiates a communication, generates a clock and terminates the communication and Slave is the one which is handled by master and acts according to the master command.
