In a recent project, I learned about the external Ram Extension of the AVR microcontroller, which is recorded here. In this paper, we use a single-chip microcomputer with a single-chip microcomputer as the testing platform and expanded 74hc573 (AHC

ReprintedIn C language, how to use macros (macro) in macro C (and C ++) belongs to the scope of compiler preprocessing and to the concept of compilation period (rather than runtime ). The following briefly summarizes the frequently encountered macro

Question: implement a function that belongs to an integer and outputs the number of 1 in the binary representation. For example, if 9 is expressed as 1001 in binary notation, two digits are 1. Therefore, if 9 is input, the function outputs 2.

Do the boot loader experiment, but use it on a USB drive formatted as FAT32.* Use Winhex to fill all the bytes of the U disk into 0.* Format the USB stick into FAT32 with the format function in UltraISO, the allocation unit is 4KB* Use the Write MBR

The original Article is here Character-based Sometimes you want to convert a macro parameter into a character constant. You want to insert a macro parameter into a string and expect it to be simply replaced with a character constant. The idea is

Network Source: http://blog.chinaunix.net/uid-14022540-id-2849095.html usage of "#" and "# # " in macros I. GENERAL usageWe use # to turn the macro parameter into a string , and use # # to fit the two macro parameters together .

Memory allocation is a core issue for C programs, and many open source software will customize their own memory allocation strategy for their software needs, and Redis is no exception. In general, however, Redis is not specifically about memory

It's easy to write complicated things. Due to functional requirements, Vczh Library ++ 3.0 is very outrageous to me. To develop and maintain traversal, reduce mistakes caused by carelessness, and enhance unit testing, regression testing, and testing

Unlike sending network packets, network packets are asynchronous, because you are not sure who will send you a network packet suddenly, so this network packet logic actually contains two things: 1. Notification after the arrival of the packet2.

One, the process replicates (or produces)The child processes obtained by using the fork function inherit the entire process's address space from the parent process, including: process context, process stack, memory information, open file descriptor,

Original: Advanced application of C language macrosOn the # and # #在C语言的宏中, #的功能是将其后面的宏参数进行字符串化操作 (stringfication), simply put a double quote in the left and right side of the macro variable that it refers to by replacing it. For example, a macro in

The scene switch in Cocos2d-x is done by calling the corresponding method, and the Ccdirector::shareddirector ()->replacescene () method is used to toggle the scene, and the parameter is the new scene to be switched. This method will release the old
