Data pointers In the programming of embedded system, it is often required to read and write the contents in a specific memory unit, and the corresponding MOV instruction is compiled, while other programming languages other than C + + have no direct access to the absolute address. In the actual debugging of embedded sy

2. network socket programming in the embedded operating system uClinuxNetwork socket data transmission is a special type of I/O, and socket is also a file descriptor. Socket also has a function call similar to opening a file. The socket () function returns an integer socket descriptor, and subsequent connection establishment and data transmission operations are implemented through this socket. There are two

Interrupts is an important part of embedded systems. Consequently, many compiler vendors offer an extensionTo standard C-to-support interrupts. Typically, the keyword is _interrupt. The following routine (ISR), point outThe errors in the code.double Compute_area (double radius) { double area = PI * radius * radius; printf ("\narea =%f", area); return 0 ;}Analysis1) ISR cannot return a value2) ISR cannot pass parameters3) In many processors

developer collects and sorts the information contained in each data sheet. Usually each of them needs to be accessed to get the peripherals up and running. key information is scattered ( or hidden ) in each type of data sheet. 5. Beware of peripheral failuresrecently I had the opportunity to port a series of microcontroller drivers to other microprocessors. Both the manufacturer and the data sheet show that the PWM peripherals are the same between the two series of microcontrollers. However, t

3rd Chapter CORTEX-A8 Processor Programming 1. Introduction to ARM programming • In the development of embedded systems, the main programming languages currently used are C and assembler. In many places, such as the initialization of hardware system at boot time, including the setting of CPU state, interrupt enable, th

Yongzhong office is an office software developed in Java and can be used across platforms. This article briefly describes how to embed yongzhong office into a browser (including Internet Explorer in windows and Mozilla in Linux. The yongzhong office embedded browser is implemented by using an applet. The yongzhong office applet embedded in the webpage is referred to as "eio_applet ". Before starting

This macro will be expanded into:if (temp) if (condition) do_something (); Else do_anotherthing (); The else at this point is not matched to th

, for example:#include int g; Double h; int foo (void) { → statement list}int bar (int a) { → statement list} int Main (void) { → statement list}6, a function of the statement list if it is long, you can also be divided into groups according to the correlation, separated by a blank line. This rule is not strictly required, usually the definition of a variable to form a group, followed by a blank line, the return statement before the blank line, for example:int Main (void) {

/word. under document.8, create a subkey value named "browserflags" and its type is "REG_DWORD". If it is set to "8", open the Word document in an independent window, otherwise, open the document in the word window Embedded in IE. Note: Microsoft Excel 7.0 worksheet is slightly different. You should set browserflags to "9" to open the document in a separate window. References: Msdn: 259970: In-Place activating document servers in Interne
