Shenzhen embedded operating system OK? Shenzhen Education Embedded Training Center teacher said that the real development of embedded computers after the advent of microprocessors. In November 1971, Intel successfully integrated the arithmetic and controller circuits, introduced the first microprocessor Intel 4004, fol

In the process of building the embedded system, the first step for the construction engineer of the system platform is usually the transplant bootloader, of course, there are several levels of migration, usually the most common is the reference EVM hardware has been modified (such as changed flash, changed SDRAM, DDR SDRAM, etc.), And is the first debugging hardw

usesGettickcountTo be easily tested for correct overflow handling. In addition, images such as PNG, bitmap, and GIF are optimized to make the image quality and size meet the requirements. 7. Why is the control so inefficient? How to reduce the use of controls? Mobile phone software is different from desktop system software. On the one hand, mobile phone processi

Bowen viewpoint open party No. 5th: Operating System and embedded development have been successfully completed Enjoy coffee with the legendary cool-man, share it success experiences with best-selling authors, and discuss new concepts with technical experts ......This is not a fantasy!On October 16, September 5, the operating system and

Serial number Course name Course Content Requirements 1 Linux operating system usage This course introduces the concepts and installation methods of the Linux operating system from a starting point. It describes the basic commands, management configurations, and editors in Linux, including the VI Editor, GCC compiler, knowledge about gdb debugger and make project management tools.

For the recent months, I was always focus on debugging in the real-time system VxWorks, and off course wasted too much time on some bugs. these bugs were tricky but all turned out to be simple after finding the root cause. There are different ways of debugging for the different types of software. obviusly, some popular Debugging Technique cannot applied to the real-time

into a mature navigation software platform. Kay lide has released a number of embedded, mobile phone and other platform navigation software versions, including support for Windows Mobile platform, Symbian platform, and of course Windows CE platform. Kailide navigation software interface 57 is shown. In addition, compa

Hardware: mini2440 software: Linux-2.6.32 I. Introduction to H.264 H.264 is a video compression encoding standard. The standard provides high-quality image transmission at a low bandwidth (less than 2 m. According to data analysis, H.264 saves an average of

Article Title: learn how to build an embedded Linux system on a VM-compile the kernel. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. 1. download the kernel · I used linux-2.4.20.t

directly sent from the device to the memory (or vice versa ). Compared with the interrupt driver, the DMA mode reduces CPU intervention on peripherals and further improves parallel operations between the CPU and peripherals. 　　Bitwise operation The bitwise operation in C language can reduce the division and modulo operation. The bit of data in a computer program is the smallest unit of data that can be operated. In theory, you can use the bit operation to complete all operations. Therefore, fle

Title: Implementation of remote debugging of GDB in embedded Linux 2008-01-11 11:22:08 Implementation of remote debugging of GDB in embedded LinuxAuthor:vickyThe remote debugging environment consists of host GDB and the target debug stub, both through a serial port or a TCP connection. Use the GDB standard Remote serial protocol to work together to realize the monitoring and debugging function of

Common interface functions of micro-embedded real-time operating system SmallRTOS Micro-embedded real-time operating system SmallRTOS is a micro-kernel real-time operating system with open source code, which is easy to transplant and oriented to deep

Implement an embedded operating system that can't do anything 1. First determine the CPU. Here we use embedded CPU for simplicity, such as the arm series. The reason why we use a short Instruction Set)The convenience of a type of CPU is that there is no distinction between the real mode and the protection mode, and linear unified addressing is adopted, that is,

itself, and the systematic method is to participate in the development of the system to provide the people.Embedded systems are equipment that controls, monitors, or assists in the operation of a device, machine, or even plant. The following four features are available: 1. Used to perform specific functions; 2. Computer and peripherals constitute the core; 3. Strict timing and stability are required; 4. Fully automatic operation cycle.The development

File transmission through serial ports between the embedded Linux System and the host I think if I want to download something from my PC to the embedded Linux System of the Development Board, many people will first think of using network tools such as TFTP SFTP to download it from the network port. But if the network i

to design a review schematic at any time based on these principles, including:A) digital power supply and analog power supply are separated.B) digital ground and analog ground separation, single point of ground, digital ground can be directly connected to the shell (EARTH), the chassis must be grounded to protect the personal safety.C) Ensure that resources in each module of the system cannot conflict. For example, the device addresses on the same I2

Startup refers to the program to run when the chip is powered on and reset. It is started as a module independent of the operating system, because the operating system needs to start this module to load and boot. Therefore, the start term is boot loader. My definition of Boot Loader includes two parts: 1. Loading OS 2. hardware and software initialization to make
