When I was interning in the first company, the leader mentioned it and I went to know , Find it and uCOS、FreeRTOS It's completely different to use ,“ Small and beautiful ” The idea of runs through the whole , especially Env and The device frame made me feel very strange , At that time, BiShe also had a lot of time at the beginning and wanted to use it . Brother wildfire's 《RT-Thread Kernel Implementation and application development practice guide 》 This book was of great help to my study at that time .

The first contribution is the first submission when completing the design Libmodbus software package , Follow the official package submission tutorial step by step , It is not a success to merge the branches of their own warehouses into the official , Mainly for some git The operation of is not very familiar .
After work, use it in depth RT-Thread, I always feel that some components or software packages are not used to , Just think I want to make my own wheels . From the simplest Led Start to key 、 Network debugging 、Ftp The server , Their own wheels are gradually increasing , As soon as people have family buckets, I'll name them Agile All right . Every once in a while, abstract some of your ideas as new family members .

Q： You developed Agile Series of software packages are highly praised by developers , Are there any unforgettable memories in the development process ？
file ！ file ！ Or documents ！ No matter how easy a thing is to use, but you don't have a manual or a heavenly book, it's difficult to promote it , Maybe I will think about what I write when I go to see it one day ？
At the beginning, writing documents was quite casual , A few hundred words in a hurry , No matter what the flood is . In the back Doxygen Later, I found that the original document can still be written like this , At this time, I made another Flag, I want to put Agile Whole family barrel document rewriting , Next is a painful period of time , First of all Agile Modbus, I can still remember those nights and weekends when I stayed up late to write documents , The feeling of choking out one word reminds me of when I wrote my composition at school . Documentation alone is not enough , A complete example is needed to make developers easy to use , Then there was another painful day . That's it Agile Modbus Present the current version .
When documents are generated by tools, I feel that the previous efforts are worth it .

Q： You are using RT-Thread When developing a project , What is the most difficult point ？
It should be the equipment frame and POSIX Well , The device framework is a novelty , and RT-Thread It provides a lot of device frameworks that you can use foolishly , But how to achieve their own bottom drive access device management , This requires you to agree with its idea , Endure a period of discomfort . meanwhile POSIX The docking of is also a great difficulty ,select The principle of implementation and how to connect need a deep understanding of the device framework .
