From here on, I will lead you small white, start programming ...The first C-language program Hello world! ：1 #include "stdio.h" //Include header file2 int main () //define Mian function3 {4 printf("Hello world!"); //Output string5 return 0; //Return 04?Well, we can clearly see that this program has a total of 4 parts:

Linux DRIVER: Hello World, linuxhelloworld After reading Windows Internals for a few days, I felt quite annoyed and couldn't see it. The author talks about the various mechanisms of Windows. After all, Windows is not open-source. Many internal implementations can only be explained by concepts and abstract. Turning to the Linux camp, the classic LDD (Linux Driver Develop) can be read smoothly and never stops

As mentioned above, "Hello World" will be the first language to learn in C, C ++ and other languages.CodeHowever, in FPGA, because of the complexity of circuit driving, similar to single-chip microcomputer, we cannot achieve "Hello World" display on the computer, but must rely on relevant hardware. Therefore, we have t

The previous article introduced the concept of Linux drive, and the basic classification of device drivers under Linux and the basis and difference of each classification, this article describes how to write a simple test driver like Hello World. and the only function of this driver is to output Hello world.Before writing a specific instance, let's take a look at
