🔌 I2C Device Driver Tutorial: Part 1 - Introduction to I2C Protocol 🔌

The Inter-Integrated Circuit (I2C) protocol is a popular serial communication protocol used for connecting low-speed peripherals to microcontrollers and embedded systems. In this multi-part tutorial series, we'll explore how to develop an I2C device driver in the Linux kernel. In this first part, we'll introduce the basics of the I2C protocol, discuss its key features, and lay the foundation for developing an I2C device driver.

Introduction to I2C Protocol:-

The I2C protocol, developed by Philips Semiconductor (now NXP Semiconductors), enables communication between integrated circuits using only two wires: a serial data line (SDA) and a serial clock line (SCL).

I2C supports multiple devices connected to the same bus, each with a unique 7-bit address.

It offers advantages such as simplicity, low pin count, and bidirectional communication, making it suitable for connecting sensors, EEPROMs, RTCs, and other peripheral devices.

Stay tuned for the next part of the tutorial, where we'll delve into the architecture of I2C devices and discuss how to interact with them in the Linux kernel.
