🖥️ I2C Device Driver Tutorial: Part 3 - Interfacing with I2C Devices in Linux Kernel 🖥️

In the third part of our tutorial series on I2C device drivers, we'll explore how to interface with I2C devices in the Linux kernel. This involves configuring the I2C bus, discovering connected devices, and communicating with them to read or write data. By understanding the Linux kernel's I2C subsystem and APIs, we can develop robust and efficient I2C device drivers.

Interfacing with I2C Devices in Linux Kernel:

1. Configuring the I2C Bus: We'll learn how to configure the I2C bus by enabling the I2C driver in the kernel configuration and loading the necessary modules.

2. Detecting I2C Devices: Using tools like `i2cdetect`, we'll identify the addresses of connected I2C devices on the bus.

3. Using Kernel APIs: We'll explore the I2C kernel APIs such as `i2c_new_device`, `i2c_smbus_read_byte_data`, and `i2c_smbus_write_byte_data` to interact with I2C devices from kernel space.

In the next part of the tutorial, we'll dive into the implementation of a basic I2C device driver in the Linux kernel, demonstrating how to initialize the device, perform data transfers, and handle errors.
