🧰 I2C Device Driver Tutorial: Part 2 - Understanding I2C Device Architecture 🧰

In the second part of our tutorial series on I2C device drivers, we'll delve into the architecture of I2C devices and understand how they communicate on the I2C bus. Understanding the structure and behavior of I2C devices is essential for developing efficient and reliable device drivers. In this post, we'll explore the components of an I2C device, including its address, registers, and data transfer protocols.

Understanding I2C Device Architecture:

- An I2C device typically consists of one or more registers accessible through the I2C bus.

- Each device has a unique 7-bit address that identifies it on the I2C bus. Some devices may have multiple addresses for different functionalities.

- Communication with an I2C device involves sending commands or data to specific registers and reading or writing their contents.

- I2C devices may support different data transfer protocols, such as byte-wise, block-wise, or combined read/write operations.
