Next to the introduction of the main I2C data structure in the previous blog post, let's go into the I2C driver code to get a glimpse of this slightly complicated driver. Since the Code already has a certain length, you can no longer copy the entire segment as before, and then analyze it directly. In order for the monks to better read their notes in the future, and for the cainiao who are more comfortable w

3.1 Overview
Previously speaking about the I2C subsystem, I mentioned using i2c-dev.c files to implement our I2C Slave Device Driver in applications. However, it implements a virtual, temporary i2c_client, which is generated as the device file is opened and abolished as the device file is cl
Some time ago, I have been engaged in the application software of the GPS navigation system. Recently, it has come to an end. I continue to pick up the driver of the Linux device!
The last time I recorded the module initialization code, I checked the code for uninstalling the module this time.

This is an entry-level problem. I used to struggle with Wince and did not know how to solve it.
Later, we saw the camera driver of wince6.0 6410/s5pv210 and found that the call and application between the original driver and the driverProgramThe call driver is the same.
There is no difference at all.

Wait Queue:
In Linux driver programming, waiting queues can be used to implement blocking of processes.
The wait queue can be thought of as a container for the save process, and the process is placed in a wait queue when the process is blocked;
When the process is awakened, the process is fetched from the wait queue.

Now, let's write our own first character device driver--light LEDs. (Imperfect, back to perfect)
Hardware platform: Exynos4412 (FS4412)
Writing the drive is divided into the following steps:
A--View the schematic, data manual, understand the equipment operation method;
B-Find a similar driver in the kernel, develop it as a template, and sometimes need to start from scratch;
C-Implement
