Module division The "planning" of module division refers to planning, which means how to reasonably divide a large software into a series of functional independent parts to fulfill the system requirements. C language, as a structured programming language, is mainly based on functions in module division (Division by function becomes an error in object-oriented design, and Newton's Law encounters relativity ), modular C LanguageProgramThe design sh

Embedded C language programming knowledge 1. When the assembly line is filled with instructions, the maximum efficiency can be realized. That is, an instruction is executed every clock cycle (only a single-cycle instruction ). If the program jumps, the assembly line is cleared, which requires several clocks to fill the assembly line again. Therefore, using jump commands as few as possible can improve progra

embedded Linux system Programming (v)--directory file functions directories in Linux are also files, and directory manipulation functions are standard IO library functions. The main functions are as follows:#include #include DIR *opendir (const char *name);DIR *fdopendir (int fd);Successfully returns a pointer to the directory stream, fails to return NULL, and sets the errno global variable. #include struct

Transferred from: http://zyg0227.blog.51cto.com/1043164/2719541. The Linux kernel has video for Linux abbreviation v4l. V4L is the basis of Linux image system and embedded image, is a set of APIs supporting image equipment in Linux kernel, with appropriate video capture card and video capture card driver, V4L can achieve image acquisition, AM/FM radio, image codec, channel switching and other functions. At present, v4l is mainly used in image streamin

Module Division Module Partition "Zoned" is the meaning of planning, meaning how reasonable to divide a large software into a series of functional independent part of the cooperation to complete the system needs.

1. Naming specificationTo make variables better understood by other developers who read the code, you need to use a prefixA (array), B (Boolean), I (4-byte integer), u (unsigned integer number), p (pointer), S (String), SZ (null-terminated string)-For example:BOOL Bflag;int iCount;Char Szname[name_len];i,j,k,m,n,x,y,z single-letter variables are used at loop control and indexing, non-abusive • Local static variables must be prefixed with s_, such as S_bflag, on the basis of other rules. • Global

embedded Linux system Programming (ii)--File Descriptor control function fcntl Because the fcntl function is too flexible and complex, the fcntl function is listed separately from the file IO , which is easy to read in detail. The function prototypes are as follows:#include #include int fcntl (int fd, int cmd, ... */arg */); fcntl fd, control of the file descriptor is performed by the cmd control
