In the past two days, I have tried to build the stm32 development environment of eclipse + GNU arm Eclipse plug-in + sourcery g ++ Lite Edition for ARM + opencd + jlink, I also use Keil very well, mainly because I recently worked on a project to make it impossible to use a commercial environment. I searched almost all the information on the Internet and found that there was very little information. I sorted out some of my accumulated information and h

[Arm note/cross-tool] Use sourcery g ++ Lite to build a cross-compilation environment 20:45:41 | category:Arm | font size subscription 1. Get the CompilerWe can compile and create a cross-compile toolchain by ourselves. However, for convenience and stability, we usually choose a mature third-party toolchain. The cross-tool chain of codesourcery is a common one. Taking arm as an example, we canTo the latest version.We can see that there are four OS pla

In order to compile the program on the computer composition and design-hardware/software interface, however, GCC on UbuntuX86 can only be compiled into the X86 assembly. Sourcery codebench out a gcc toolchain for compiling to the MIPS assembler. Our usual compilation, called Local compilation, is compiled into a compilation under the current platform. Instead, cross-compilation can be compiled into other platforms (the platform of the compiled platfor

My personal understanding is as follows: Technology:I understand it as a general technology, such as forums, blogs, and portals. They can be used wherever they are needed, and may only need a few modifications.Professional Technology:Such as finance, manpower, production arrangement, ERP, and sales management. You are familiar with a major. For example, Kingdee and yonyou are financial software providers.Industry Technology:Such as GSP software for sale in the pharmaceutical industry, Word Se

With the rapid development of the Internet, communication technology is experiencing a huge revolution, because the number of users accessing the network rapidly increases. As a network connected to the end users in the communication network, the access network has become a hot topic in network technology. Currently, the main access technologies include hybrid fiber/coaxial (HFCs) access technology, optical fiber access technology, copper wire access

13 core technologies of J2EE and J2EE13 core technologies I. JDBC (Java Database Connectivity) JDBC APIs provide a unified way to access different databases. Like ODBC, JDBC shields developers from some details. In addition, JDBC access to databases is also platform-independent. II,JNDI (Java Name and Directory Interface) The jndi api is used to run the name and directory services. It provides a consistent

C ++ basics, important technologies, and basic technologies1. Implementation of class and object 1.1 The first method is to define the member functions of the class in the class body.The second method is to place the implementation of the member functions in the class body. In this case, the domain operator ":" is required, which has the same effect as the first one. Class apple {public: // data member int index; // member function int getindex () ;};

Java EE was originally in the browser and the client machine. At the time, many people questioned whether it was suitable for server-side development. Now, with the increase in Third-party support for the JAVA2 platform Enterprise version, Java is widely accepted as one of the preferred platforms for developing enterprise server-side solutions. The Java EE platform is comprised of a suite of service (services), application interfaces (APIs), and protocols that provide functional support for d

technologies of MySQL are familiar, such as the transaction mechanism (Isolation level , locks, etc.), to trigger, partition and other technologies have a certain understanding and application; For MySQL performance, there are disk optimizations (SAS migration to SSD), Server optimizations (memory, server itself configuration), and other core performance tuning options in addition to the two phase (Innodb_

conventions. JavaBean can provide common functionality and can be reused, which allows developers to extract some key functions and core algorithms to encapsulate as a component object, which increases the reuse rate of code and the security of the system. Advanced Web projects are applied to all of these technologies, and joint use and collaborative development between them can improve the efficiency of development and the performance of the system.

This chapter provides a general overview of WebService technologies and client-side invocation techniques. The figure above contains almost all the relevant content of the current webservice. I'm going to go through two big chunks to illustrate, that's the service side, the client. The service side mainly introduces the following 3 kinds: 1. Axis1 or Axis2 release WebService. 2.
