1、 Preface

As a software developer , In addition to procedural ability and literacy , You should also skillfully use all kinds of commonly used auxiliary tools , So-called “ A good workman does his work well , You must sharpen your tools first ”; Through these tools, you can improve your professional quality , And choosing appropriate tools in work can get twice the result with half the effort .

1.1、 Purpose

What this article writes is to introduce various commonly used software , We can choose appropriate tools to improve our work efficiency .

2、 Common software

2.1、IDE

SCM software development often uses IDE（ Embedded integrated development environment ）, because IDE The software integrates editing 、 compile 、 download 、 Debugging and other functions , Very convenient in development , Because there are many kinds of single chip computers , Used therefore IDE There are many kinds of software , Here are some common IDE And SCM , Such as ：

• KEIL4：51 MCU and so on
• MDK（KEIL5）：STM32 etc. ARM Series of microcontrollers
• IAR（for stm8/arm）：STM8、STM32 etc. ARM Series of microcontrollers 、K60 Wait for Freescale
• SPC5 Studio：ST The company's new SPC560/SPC570 And so on
• CodeWarrior：M(S)PC5604 etc. NXP（ Freescale ） Series MCU
• other

For the used IDE Further familiarity with the software , Be proficient in using related IDE Many things can be solved in software development and hardware and software debugging , I won't go into that .

2.2、 Version control tools

Version control software provides complete version management function , Used to store 、 Tracking Directory （ Folder ） And file modification history , It is a necessary tool for software developers , It's the infrastructure of a software company . The highest goal of version control software , It supports the configuration management activities of software companies , Track development and maintenance activities for multiple releases , Timely release of software .

Generally speaking , In the actual software development process , You will often encounter when you implement a certain function or want to optimize software code , Will back up the entire project replica , Avoid problems after software modification , But because I don't know what has changed, I can't restore the previous software code .

So in the process of software development , There are often many copies of the project , But more than one copy , I don't know what the corresponding state of each replica is , Maybe some people have considered , Therefore, when renaming a copy, there will be some simple descriptions to record the status of the current project copy .

Why use a version control tool ？

Backup of the current state of the software , Version management （ Version fallback is possible ）

Help us record and track the changes in the contents of various documents in the project （ You can operate under the same project directory ）

Improve code quality ; Because there are some changes in the code without any comments , Through the version record, you can find , You can also delete useless code

Collaborative development ; When multiple people develop at the same time , If you copy it to others in the form of a copy for collaborative development , There will be many problems , Because I don't know whose version is the latest

It can reduce the occupation of the project （ The size here refers to the hard disk size occupied by the software and its copy , Through version control tools , It can reduce the occupied hard disk size ）

What are the version control tools ？

• Git

• Git It is the most advanced distributed version control system in the world , Use Git and Gitlab Building a version control environment is the most popular version control method for Internet companies （ One of the most famous is Github, The largest open source code base ;Gitee, Open source China Code cloud ）
• Git Is a free open source distributed version control system , Designed to handle everything from small to large projects quickly and efficiently
• Git Easy to learn , It takes up little memory , Lightning fast performance
• The operation is relatively complicated （ The form of the command line ）, But by using Git Gui Tools , You can get started quickly , But it comes with it Gui Tools are not easy to use , Third party developed can be used , Such as SourceTree（ I often use , Because there are also extremely convenient gitflow Branch management function , It is recommended to use for the first time Git You don't need branch management , Because it is difficult to understand the words just used , Easy to give up ）, relevant GUI For comparison of tools, please refer to Several Git GUI Client tools

Here's the picture , This is for me Git GUI Software SourceTree Managed code , Which used gitflow Branch management , If not , One master Branch is OK , That is, there is only one blue line in the map , Represents each version （ It can be understood as a copy ） Related records of , You can see two stable versions in the figure （ label V0.1.0 and V1.0.0） The file is obviously different

Tutorial reference ：Git course

• SVN

• TortoiseSVN Is a very easy to use cross platform version control / version control / Source code control software
• SVN Is a free centralized version control system
• There are also available GUI Tools , Such as TortoiseSVN etc. , May refer to SVN Client tools
• Tutorial reference ：SVN course

• other

• Such as VSS、CVS etc. , Because I didn't touch , So I don't know , Interested in Baidu

2.3、 Document comparison tool

We often encounter some files that need to be compared , Especially some code 、 Text 、 Between pages or folders , We really need a tool that can clearly analyze all the differences between them , It is convenient for modification or reference , Although it can pass Git And other version management tools can also see the difference , But it is more convenient to use a professional file comparison tool , The available software is Code comparison software .

I recommend using Beyond Compare Software , It's more convenient to use , And it's powerful , But this software is charged （ Official standard edition +Win/Mac/Linux ￥259 permanent ）, But it has 30 The evaluation period of days is free （ It can be reset when the evaluation period expires , There are tutorial methods on the Internet ）.

2.4、 Code reading artifact

Source Insight Is a program editor and code browser , Code editor classic .SourceInsight It provides the fastest navigation to the source code and the source information of any program editor , As a mature IDE Software ,Source Insight It is obviously not used for development and debugging IDE convenient , But in terms of reading the source code , It can be said that it is better than .

When you use source Insight After looking at the code or analyzing the code , Make sure you don't want to see code with other code editors anymore , It's better than any other code reader , Powerful , It has a built-in pair C/C++, C# and Java And so on , Support for almost all languages , Such as C、C++、ASM、PAS、ASP、HTML Such as common . Of course , except Source Insight Outside , also VS code Software （ free ） etc. , But I haven't used it yet VS code , No introduction , It is also very good to use , Personal choice .

2.5、 Text editor

The computer comes with a text editor , As a developer , Not very suitable. , So you need a professional text editor , Such as UltraEdit（ charge ）、Notepad++ Support multiple syntax highlighting and other functions , Select available for reference Several easy-to-use text editors

UltraEdit Is a powerful text editor , You can edit the text 、 Hexadecimal 、ASCII code , Instead of Notepad （ If the computer configuration is powerful enough ）, Built in English word check 、C++ And VB Instructions highlight , Multiple files can be edited at the same time , And even if you open a large file, it won't be slow .

Notepad++ Is a very distinctive editor , The software is small and efficient , Support 27 Programming languages , Take all C,C++ ,Java ,C#, XML, HTML, PHP,JS etc. . Open source software , Free to use , It also supports various popular computer programming languages .

2.8、 Source formatting tool

Prior to Programming specification for embedded software development （ Four ） in , Be able to write code according to this rule when developing by yourself , But there is no guarantee that others will follow this , If you need to read someone else's source code , When the source code style is very bad , It's killing , Although you can adjust the code style yourself , But it took a long time , Also very tired ;

Astyle Is an open source formatting tool software , Integrated in the IDE Or text editor software , As a script auto format words code style , It is very convenient . Here's the picture , Just open a bad code file , Through integrated Astyle Tools automatically format code styles （IAR、KEIL And other software can also be configured Astyle Custom tools , Can own Baidu , Format the code according to your favorite style , The command line option I use most often is “ --style=allman -t -xV -C -f -p -H -k3 -y -xb -j -U %f”）.
