My Programming Journey—Driver

The English name is "Device Driver", and the full name is "Device Driver". It is a special program that enables computers and devices to communicate. It can be said to be equivalent to the interface of the hardware. Only through this interface can the operating system control the work of the hardware device. If the driver of a device is not installed correctly, it will not work properly. Therefore, the driver is praised as "the soul of hardware", "the master of hardware", and "the bridge between hardware and system".

　　I don't remember when I first heard the word programming. I heard it in high school. At that time, I didn't really understand what programming was. I just thought it was fun and that programmers were awesome. Facing such a pile of code, how much patience and care are needed. I really came into contact with programming in my freshman year, but I didn't learn it well at that time. I was immersed in the feelings of coming to college at that time, and then I gradually lost myself. I regret it now, really regret it, but I know that it's not too late to learn now! I really learned programming after learning microcontrollers, and then I used assembly language. Others say that assembly language is difficult to learn and they are all learning C language, but strangely, I think the opposite. The teacher also said that assembly language is the language closest to hardware, so its importance is beyond doubt, but it has some shortcomings, so C language has to be used. Therefore, people who study hardware must learn these two languages ​​well.

　　Although I knew this, I didn't have the enthusiasm, passion, or desire to learn it well at that time, until...

　　Until I read Yu Zhennan's "My University": In the design, dual single-chip microcomputers are needed to realize the driving of LCD, keyboard, and printer, and also responsible for data communication with the following circuit part (the most important part). We kept fighting for four days and four nights, and we kept our fighting spirit high. I stared at the computer screen for nearly a hundred hours in a row, writing my largest driver. At that time, my heart seemed to beat again, as if I was back in high school, back to the time of struggle, that kind of enthusiasm and passion, which is what I need most now.

　　Now, most importantly, GO!
