5.1	88	= 2. Getting Start with Hello World =
2.1	89
5.1	90	== 2.1 About this demo ==
2.1	91
26.2	92	In this Getting Start Example, we will show how to design a simple Display UI and upload it to LTS5. This UI has a button , when user click the button. The Web UI will jump to a new page.
2.1	93
5.1	94	== 2.2 Install Software Running Environment ==
2.1	95
26.2	96	The ESP MCU can be developed using ESP-IDF, Arduino, or MicroPython. For this project, we utilize ESP-IDF for compilation and Visual Studio Code (VSCode) for editing.
2.1	97
26.2	98	=== 2.2.1 Install VSCode and ESP-IDF extension ===
	99
	100	Firstly, download and install VSCode for your computer's operating system from the official website: [[Download Visual Studio Code - Mac, Linux, Windows>>url:https://code.visualstudio.com/download]].
	101
	102	Next, you need to install the ESP-IDF extension within VSCode. The detailed operation steps are illustrated in image 1.
	103

	105
	106	image 1 ESP-IDF extension install
	107
	108	Links for reference: [[Install ESP32 ESP-IDF on Windows and Integrate with VS code (esp32tutorials.com)>>url:https://esp32tutorials.com/install-esp32-esp-idf-windows-integrate-vs-code/#:~~:text=In%20this%20tutorial,%20we%20will%20show%20you%20how%20to%20install]]
	109
5.1	110	=== 2.2.2 Install SquareLine Studio ===
2.1	111
26.2	112	The version we are utilizing for this software is 1.4.2. You can download it from the official link: [[SquareLine Studio - Download the current version of SquareLine Studio>>url:https://squareline.io/downloads#lastRelease]].
2.1	113
26.2	114	Please note that this software necessitates the registration of a license prior to usage, and various licenses come with distinct limitations. For instance, the free version imposes restrictions such as a limit of 1 component, 150 widgets, and 10 screens. However, for first-time downloads, you are granted unrestricted access for a period of 30 days without the need for immediate registration.
2.1	115
26.2	116	== 2.3 Simple usage of SquareLine Studio and export UI code ==
2.1	117
26.2	118	After launching and logging in to this software, create a project as shown in the following image 2. The version of LVGL is 8.3.11.
2.1	119
26.2	120	[[image:1727229550717-684.png]]
2.1	121
26.2	122	image 2 create a SquareLine project
	123
	124	Next, we need to make some settings for this project. By clicking in the specified order on image 3, we can see the page as shown in image 4.
	125
	126	[[image:1727229582471-566.png]]

	129
	130	[[image:1727229618724-758.png]]
	131
	132	image 4 modify project settings
	133
	134	Now we can start to use this software. The steps for creating this UI are shown in image 5-10.
	135
	136	[[image:1727229653254-680.png]]
	137
	138	image 5 create a UI(1)
	139
	140	[[image:1727231038705-173.png]]
	141
	142	image 6 create a UI(2)
	143
	144	[[image:1727229682537-381.png]]
	145
	146	image 7 create a UI(3)
	147
	148	We repeat the steps of screen1 in screen2. Then we get screen2 as shown in image 8.
	149
	150	[[image:1727229715361-392.png]]
	151
	152	image 8 create a UI(4)
	153
	154	Finally, we add click event for screen change to button1 in screen1(shown in image 9) and button2 in screen2.
	155
	156	[[image:1727229740592-843.png]]
	157
	158	image 9 create a UI(5)
	159
	160	The event settings of button1 are as image 10 shown. The event adding operation of button2 is similar to button1.
	161
	162	[[image:1727229760857-521.png]]
	163
	164	image 10 create a UI(6)
	165
	166	== 2.4 Integrate UI Code to ESP-IDF Project ==
	167
	168	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.
	169
	170	[[image:1727229798126-306.png]]
	171
	172	image 11 export UI file
	173
	174	[[image:1727229821582-258.png]]
	175
	176	image 12 exported UI file
	177
	178	Create a empty directory entitled ‘ui’ in path “basic_prj/app_components/ui/”, and then copy all UI code exported to this directory.
	179
	180	[[image:1727229845835-509.png]]
	181
	182	image 13 open CMakeLists.txt
	183
	184	[[image:1727229892636-154.png]]
	185
	186	image 14 modify CMakeLists.txt
	187
	188	The last step of integrating is adding two lines of code in main.c file.
	189
	190	[[image:1727229926561-300.png]]
	191
	192	image 15 add “ui.h”
	193
	194	[[image:1727229955611-607.png]]
	195
	196	image 16 add “ui_init()”
	197
5.1	198	== 2.5 Test Result ==
2.1	199
26.2	200	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.
