What is I2C bus error?
I2C Bus Error Condition The bus error condition is a generic error that indicates a hardware issue. In this case, a bus error occurs when a START or STOP condition occurs at an illegal position in the format frame.
Why I2C bus is busy?
I2C prevents data corruption by performing a wired-AND operation as the I2C interface has open-drain or open-collector output. When the SDA line is low that translates in the I2C bus as being busy.
What is I2C good for?
Developed by Philips in the 1980s, I2C (alternatively spelled I2C) has become one of the most commonly used serial communication protocols in electronics. I2C facilitates communication between electronic components or integrated circuits, whether the components are on the same PCB or connected with a cable.
Which is the I2C messaging example?
9. Which is the I2C messaging example? Explanation: The 24c32 EEPROM, which uses two request bytes that are called Address high and address low. These bytes are used to address bytes within the 32 kbit supported by that EEPROM.
How is the I2C bus designed to work?
Very often the peripheral will just blithely ack every byte that it reads from the slave regardless. The I2C bus is designed to be driven only through open-drain connections pulling the bus down, it is pulled up by a pair of pull-up resistors (one on the clock line and one on the data line).
How are two wires connected in I2C protocol?
I2C is a low-bandwidth, short distance protocol for on board communications. All devices are connected through two wires: serial data (SDA) and serial clock (SCL). I2C two wire bus layout.

Are there any timeouts in the I2C protocol?
Since I2C is essentially transaction/packet based and it does not include timeouts in the specification (SMBUS does of course, but most slave sensors conform to I2C only) there is a real chance that you are going to reset your host processor (or bus master) in the middle of such a transaction.
