105 += 2.  Getting Started with Hello World =
106 +
107 +== 2.1  About this demo ==
108 +
109 +
110 +This getting started example demonstrates how to design and deploy a simple display UI for the LTS5 device. The example includes:
111 +
112 +* Creating a basic UI with a single button.
113 +* Implementing functionality to navigate the Web UI to a new page when the button is clicked.
114 +* Uploading the UI to the LTS5 device.
115 +
116 +By completing this demo, you will gain foundational knowledge for customizing the LTS5 interface and building more advanced IoT applications.
117 +
118 +
119 +== 2.2  Install Software Running Environment ==
120 +
121 +
122 +The **ESP MCU** supports development with **ESP-IDF**, **Arduino**, or **MicroPython**. We use **ESP-IDF** for compilation and **Visual Studio Code (VS Code)** as the development environment for this project.
123 +
124 +
125 +=== 2.2.1 Install VS Code and ESP-IDF extension ===
126 +
127 +
128 +First, download and install **VS Code** for your operating system from the Visual Studio Code website: [[Visual Studio Code - Mac, Linux, Windows>>https://code.visualstudio.com/download]].
129 +
130 +Next, install the **ESP-IDF** extension within **VS Code**. Detailed steps for this process are shown in Image 1.
131 +

138 +
139 +
140 +=== 2.2.2 Install SquareLine Studio ===
141 +
142 +
143 +Download and install the latest version of [[SquareLine Studio>>https://squareline.io/downloads#lastRelease]] on your computer. It supports Windows, Linux, and Mac OS. The software version we are using here is 1.4.2.
144 +
145 +[[image:squareline.io_downloads.png]]
146 +
147 +
148 +After installation, you can use SquareLine Studio with a **PERSONAL license plan**. Click **LOG IN** and create a free account using your email address. Then activate your PERSONAL license plan for free. You don’t need to provide any credit card information. However, the PERSONAL license plan has the following limitations:
149 +
150 +* Max. 10 screens
151 +* Max. 150 widgets
152 +* Max. 5 global colors
153 +* Max. 2 themes
154 +* Max. 1 component
155 +
156 +
157 +== 2.3 Simple usage of SquareLine Studio and exporting UI code ==
158 +
159 +
160 +After launching and logging into the software, create a new project as shown in Image 2.
161 +
162 +* Select the major **LVGL** version as **8.3**.
163 +* Select the **Desktop** tab.
164 +* Select  **Eclipse with  SDL for  development on PC**:
165 +* In the **PROJECT SETTINGS**, select **LVGL version** **8.3.11**
166 +* Select the **CREATE **button.

170 +
171 + Image 2: Creating a new SquareLine project
172 +
173 +
174 +Next, you need to configure some settings for this project. By clicking in the specified order shown in Image 3, you will be directed to the page displayed in Image 4.
175 +
176 +* Select File  -> Project Settings
177 +
178 +[[image:1727229582471-566.png]]
179 +
180 + Image 3 accessing project settings
181 +
182 +
183 +In the PROJECT SETTINGS dialog box, configure/modify the project settings:
184 +
185 +* **UI Files Export Root**: Select a folder on your computer to store the UI files.
186 +* **LVGL Include Path**: Set this to **lvgl.h**
187 +* **Click on the APPLY CHANGES button.**

190 +
191 + Image 4 Configure/modify project settings
192 +
193 +
194 +Now you can start building the UI. Follow the steps below:
195 +
196 +
197 +**~1. add widget**
198 +
199 +To add a widget, you should click a widget you want to add at the area entitled “Widgets”. In image , demonstrate a add process of label, button, and image 5.
200 +
201 +[[image:image-20240928111412-6.png||height="526" width="864"]]
202 +
203 + image 5 add widgets
204 +
205 +**2. modify widget**
206 +
207 +The area for modifying widgets is called "Inspector". There are four parts in the "Inspector" tab. We use three of them more frequently, excluding "COMPONENT". The second part is aimed at adjusting the layout, size, position, alignment, flags, and states, etc. of widgets. The name of the second part indicates the type of widget it is representing, and in image 6, it is "BUTTON".
208 +
209 +[[image:1727485118799-984.png]]
210 +
211 + image 6 the button widget's "Inspector" tab
212 +
213 +Second part: "Layout" means a auto position-management for widgets contained in the parent widget. "Transform" includes size, position and align modification.
214 +
215 +[[image:1727485251053-655.png]]
216 +
217 +image 7 the button widget's "BUTTON" tab
218 +
219 +Third part: It is an area of style setting.
220 +
221 +Fourth part: It is an area for adding events. In image 8, it is adding a click event to a button. If the button is clicked after the click event is added as shown in image 8, the current screen will fade into another specified screen, and the switching process will last 500ms.
222 +
223 +[[image:1727485480434-713.png||height="395" width="290"]]
224 +
225 + image 8 add event for button
226 +
227 +**3. change label widget content**
228 +
229 +Modify the content in text as shown in image 9, the text content of label widget will be changed accordingly.
230 +
231 +[[image:image-20240928090825-1.png||height="327" width="391"]]
232 +
233 + image 9 modify text content of label widget
234 +
235 +**4. Add image into project**
236 +
237 +To use the image widget, you should first add an image to your project. The image format must be PNG, and its resolution should not exceed 800x480 pixels. There are two ways to add an image file. One way is to move your image into the folder "…/squareline project/assets/", as shown in image 10. The other way is to click the "ADD FILE INTO ASSETS" button, then select an image from your computer to import. After adding, you can see the image in the "assets" area in SquareLine Studio, as demonstrated in image 11.
238 +

244 +
245 + image 11 use image widget in SquareLine Studio
246 +
247 +**5. The relationship between widgets**
248 +
249 +There are two common relationships between widgets: one is parallel, the other is parent-child. The parallel relationship means that widgets' relative position is based on a collective object of reference. In parent-child relationship, the parts of the child object that are outside the boundaries of the parent object are not visible by default. Therefore, we need to adjust the position of the child object so that it falls within the range of the parent object, allowing it to be seen as illustrated in image 13.

258 +
259 +**6. Preview the final effect**
260 +
261 +An advantage of this kind of software is that you can edit the UI with quick previews. In other words, it provides a way of combining graphical programming with simulation immediately.

270 +== 2.4 Integrate UI Code to ESP-IDF Project ==
271 +
272 +
273 +To achieve the integrating, we first need to export the UI code, then make some modifications, and finally relocate the UI code to a specific position within the project.
274 +
275 +[[image:1727229798126-306.png]]

282 +
283 +Create a empty directory entitled "ui" in path "basic_prj/app_components/ui/", and then copy all UI code exported to this directory.

292 +
293 +The last step of integrating is adding two lines of code in main.c file.
294 +

296 +
297 + image 19 add "ui.h"

302 +
303 +
304 +== 2.5 Brief introduction of hello world project ==
305 +
306 +
307 +The project consists of two screens. The first screen displays the company's logo, the project name, and a button to navigate to the next screen. The second screen presents some information about this HMI screen product through an image and includes a button to return to the previous screen.
308 +
309 +
310 +== 2.6 Test Result ==
311 +
312 +
313 +By pressing the button lying bottom right, the screen can switch to another as expected. This indicates that the UI file has been successfully integrated into the project and is now effective.
