Linux under the I2C-driven loading process, divided into I2C equipment layer, I2C adapter layer and I2C core layer
The I2C device driver layer is the drive we write for a particular I2C device, and the following is the I2C-driven registration process I understand.
In the I2C device driver we write, we call I2c_add_driver () to start I2C device-driven registration, which calls

A big difference between the program under the command line and the program under the graphical interface is input and output. Graphics Interface Program is event-driven, no matter what function to complete, must start the main window; command-line programs are instruction-driven, what instructions users give, what input they give, what output the program produces, and then the program ends. Understanding this is essential if you want to move from a graphical interface to a command line operatio
