Detailed description of Embedded c language development and Embedded c practice Detailed description of Embedded C Language Development I. Overview 1. Why C language in embedded development? Because the kernel of the operating system uses the C language, and the C language also has the following advantages: (1) Excell

Embedded System watchdog implementation, embedded system watchdog The work of the embedded system is often affected by external electromagnetic fields, causing the program to run and run into an endless loop. the normal operation of the program is interrupted, causing the entire system to be stuck, unexpected consequences occur, so real-time monitoring of the ru

Embedded software does not necessarily need to learn a lot of hardware knowledge (some words of course, the more the more). will use some burning writing tools, compiling, debugging tools (such as JTAG) on it, the time to use the current learning. Development tools are not fixed, and generally do not need the IDE, with a text editor can write code (such as Vim,emacs, Nano, Sublime).Compile general use of GCC variants.

PCCW embedded Yang share embedded learning with you 13 golden hairHttp://www.lupaworld.com/thread-860415-1-1.html Embedded development learning is a continuous accumulation and summary of the process, from an embedded development engineer for us to summarize the 13 princi

With the development of embedded systems today, the hardware platforms corresponding to various microprocessors are generally generic, fixed, and mature, which greatly reduces the chance of introducing errors from the hardware system. In addition, because the embedded operating system masks the complexity of the underlying hardware, so that developers can do most of the work through the API functions provid

Linux driver development focuses on content-from "embedded Linux driver template overview and project practices", embedded driver development This article is excerpted from my lecture on Embedded Linux driver templates and project practices. Initially, it seems that the development of Linux Device Drivers involves a lot of content, and the devices that need to im

[Embedded high-paying employment course] embedded System Employment Training classIn order to cultivate the embedded development engineers who meet the needs of enterprises, solid foundation, wide knowledge, strong skills and innovative spirit, through the system learning of this course, students can study the embedded

The previous article introduced the Starting Process of the resource shortage embedded system, and now introduces the Starting Process of the resource extensiveness embedded system. Generally, memory-wide and rich operating systems are plug-in with SDRAM, And the CPU computing power is relatively strong, such as SoC based on core such as cortex A and MIPS 74k. Is the difference between the two

A simple understanding of C language Embedded Assembly, Embedded Assembly Recently I have looked at the implementation of the spin lock. The main implementation of the loop lock of the self-selected lock is similar to the following. This implementation uses an Embedded Assembly (from the sanos kernel, the source code has two implementations, there is no problem w

This paper introduces the start-up process of resource-scarce embedded system, and introduces the startup process of resource-rich embedded system now.Memory resource-rich operating system is generally plug SDRAM, and CPU computing power is stronger, such as based on Cortex A, MIPS 74k and other core Soc.Is the difference between two types of embedded system arch

Due to hardware restrictions in embedded systems, the huge and bloated X Windows in Embedded Linux systems are not suitable. We need a high-performance, lightweight GUI system. Generally, the GUI suitable for Embedded Linux systems has the following features: 2. It is small in size and occupies less flash and ram. When installing the GUI system, you should be abl

Embedded Linux and 51/430/stm32 Embedded development of the Difference and Association summary: Microcontroller series: 8051, MSP 430, STM32 f0-3 (ARM cortext m0-m3 series), etc.The main feature is that there is no memory management unit, no Linux operating system with virtual memory, only bare-metal programs or a Ucos class of real-time operating systems can be run. The main work is peripheral driver devel

System Disk (SD) includes the operating system, driver, middleware, application and font library, UI resources, and other files. This article describes the file system design of the SD area. The primary goal of a file system is to locate and read/write a single file. Generally, the Code cannot be modified by itself, that is, no write operation is performed after mass production. The SD File System of the embedded system is designed to locate a file an
