Before analyzing the driver, we will analyze the model of the IIC subsystem. There are 2 ways to IIC device drivers, one of which is to write user-driven through a universal driver. The other is to add a IIC device driver directly to the IIC subsystem, such as a driver for AT24C02. Next we'll learn how to write a I
