After discussing the initialization and deletion of drivers for I2C devices and I2C adapters, we will focus on several function operations in file_operations, paste the file_operations struct code first. Let's see which functions are included. Static const struct file_operations i2cdev_fops ={ The structure must be quite clear. Therefore, the I2C Driver provides the following operation functions for the user space: 1. no_llseek 2. i2cdev_read 3. i2c

I. Overview Speaking of writing I2C drivers in Linux, there are currently two main methods: one is to treat I2C devices as a common character device, the other is to use the Linux I2C driver architecture. The two drivers are compared below. The advantages of the first method (corresponding to the disadvantages of the second method) include:● The idea is straightforward and you don't need to take the time to understand the complex I2C subsystem operati
