In the fourth chapter, the Android application development environment and the Linux kernel development environment are introduced. Both sets of development environments are prerequisites for Linux development and testing. With two sets of development environments, it's a good place to think about where the Linux drivers should run and what the environment is. This is also the fifth chapter of the content.When a Linux driver that has finished testing is put on a

Introduction: Mjpg‐streameris an open source software for capturing images from a webcam camera, streaming them over an IP-based network to a browser such as a FIREFOX,CAMBOZOLA,VLC player, a Windows Mobile device, or another browser-owned mobile device. Mjpg-streamer can access the Linux UVC compatible camera via file or HTTP mode. ————————————————————————————————————————————————— This article makes a migration record. The day before yesterday bought a Mai Q5 USB camera, ready for graduation d

This article is original. If you need to reprint it, please indicate the author and the source. Thank you! In a checkerboard composed of 2 ^ K * 2 ^ K squares, there is a square different from others, if you use the following four types of L-shaped bone cards to cover all the squares except this special square, how can you cover it. Four L-type dominoes, such as 1 Figure 1 Special square 2 in the chessboard Figure 2 The basic principle of implementation is to divide the 2 ^

After many days of QT transplantation, we finally got it out today. Record the learning process, but it makes me sad. Let's talk about the QT source code package. I was very confused when I first installed QT, And I had X11, embedded, and everywhere. Now I understand that X11 can be installed to develop applications running on a PC, and some QT development tools designer and qvfb will be generated. Install embedded to develop QT applications running on the Development

Analysis and implementation of board coverageI. What is a checkerboard overlay?First of all to understand what is a special square in a 2^k*2^k of the board, if just a square and other squares, it is called a special box, it is obvious that special squares appear in the position of 4^k, that is k>=0, there are 4^k different special chessboardBoard Overlay: with 4 different L-shaped dominoes covering a given

1. OverviewEmbedded system consists of hardware environment, embedded operating system and application, hardware environment is the hardware platform of operating system and application, it has different requirements depending on the application. The diversity of hardware platform is the main feature of embedded system, how to make the embedded operating system run effectively on different hardware platform is the key problem in the development of embedded system. The solution is to provide a ha

Linux Internet use Bridge, set Windows,linux, the IP of the Development Board is 192.168.1.X1,192.168.1.X2,192.168.1.X3 respectively. This is important! Must be bridged! The original because in school with IPv6 net plus Bras,ip is automatically obtained, so before Linux Internet use is NAT, instead of bridging, is not know the IP of
