At this point, I believe you will be able to use the simple tool;


After getting familiar with the tools, let’s take a look at the development rules of this screen;

  1. Understand the directory structure of the project, you can know what the project contains, and in which directory our code, UI and resources are stored;
  2. Next, let's take a look at what content is automatically generated by the tool, what is the correspondence between the UI file and the source code and the control naming rule on the UI; After understanding these, we know where our code needs to be filled in and how to operate the controls;

Control articles

The development interface is inseparable from the use of each control. In the navigation bar of the document, there is a special chapter to introduce the use of each control —— Control Introduction

There are two upgrade methods:

  1. Make image file —— update.img file; in this way, the program is solidified into the machine, and the program is still there when power is off. Pay attention to the normal download The difference between debugging; this method is also our most commonly used;
  2. Make a flash card —— format the whole machine; the system has a new version update, we will officially provide the corresponding sd file, make it into a flash card and flash the machine to upgrade; like: the system can’t turn on, The system needs to support new functions or fix related bugs, etc., in these cases, you need to flash the machine;
