VCC corresponds to Arduino Development Board 5V GND Connection Gnd TXD Connect TX Rxd receiving RX GPI00 Connect Gnd (This is uploaded when used, upload must be grounded, otherwise it will cause upload failure) Wiring is not very simple. Attach a picture 2. Then download the Esp8266 extension library. Open the IDE and click File--preferences, as shown in Fill this URL into t
SQLite, a lightweight database that adheres to the acid-related database management system, is designed to be embedded and is now used in many embedded productsIt occupies very low resources, in the embedded device, may only need hundreds of K of memory is enough. It can support Windows/linux/unix and so on mainstream operating system, and can be combined with many programming languages, such as TCL, C #, PHP, Java, and ODBC interface, also compared to MySQL, PostgreSQL, the two open source worl

NFS file system of Linux virtual machine on the Development Board Http://apps.hi.baidu.com/share/detail/48189956 Today, I did an experiment on embedded applications. How can I run cross-compiled applications on your host on an embedded system? Here I chose to mount the NFS file system over a network. My lab environment: The host machine is a virtual machine centos5.4 The target machine is Linux on mini2440. Here I use a crossover network cable to conn

recently, due to the drive experiment on the TQ2440 (ARM9) board, cross-compiling is done on the host (ubuntu13.10) for the system kernel on the front target board. One, cross-compiling of the kernel: 1. Prepare 2.6.30.4 version of the kernel source package, which I use the embedded company provides kernel source package linux-2.6.30.4_20121214.tar.bz2. 2. Open Terminal Input command: Tar vxjf linux-2.6.
First. NFS Service configuration1. Set up the board IP, the same network segment2. Development Board Operation: Ifconfig eth0 192.168.1.203. Test if you can ping the pass: Ping 192.168.1.194. Test whether the board IP is occupied:On the host: sudo ifconfig eth0 down to see if the IP on the Development Board is disconne

The switch in the use of the process, in a dual-machine state can not run, through detection, the signal is the standby side of the circuit board is not normal. This fault is obviously a hardware failure. First of all, we can replace the circuit board of the standby side with the replacement method. If the fault is still not gone, the real fault is not here. Racks, modules, power supply and connecti
We can see all kinds of message boards on many websites, which is one of the main means of communication between website and visitor. A reasonable design, the interface beautiful message board program can reflect the site from the side of good service, to visitors to leave a good impression, enhance the user's confidence in the site. The message board from the procedural point of view is actually very simpl

The recent product line research and development system formally review Board this excellent web-based code review open Source tool into the development process, as the product line within the project team for code review of the auxiliary tools. My attention to review board for nearly two years has not been wasted, but there is a fairly good result. But the formal use of review
Allows you to easily debug the software download function in single-board security mode in Win32 environments.Wen Huimin (wenhm@sina.com) Abstract:This article first introduces the low efficiency and complexity of software download debugging in a single board environment, and then analyzes the feasibility of debugging software download in a Win32 environment. The specific implementation process for debuggin
0. Prefaceactually quite busy, but this article summarizes the content I probably got two days, so still want to summarize, feel is relatively trivial, but lest next time again to do part of the work wasted energy. Most of the tutorials on the web probably teach a Windows computer to do a client, a Linux virtual machine, and then connect to the board. I directly to the windows of that machine province, because I am not too accustomed to use Windows to
I was in the process of developing thinking about whether I could sign in to the Development Board in Ubuntu, the answer is YES! There's more than one way to sign in, and here's how to log in to the board using Telnet. Just imagine, if you can login to the Development Board in Ubuntu, then you can easily debug on the same platform. And then I also thought about a

For details, see my previous article, in this article, we will explore a new way to locate the board. Analysis After observation
1. First install the TFTP server in Linux, see the previous article reproduced in the log. It's basically no problem.2. 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
