 + 
 +===== Installing using Arduino IDE ===== 
 + 
 +Programming the ESP32 
 + 
 +An easy way to get started is by using the familiar Arduino IDE. While this is not necessarily the best 
 + 
 +environment for working with the ESP32, it has the advantage of being a familiar application, so the 
 + 
 +learning curve is flattened. We will be using the Arduino IDE for our experiments. 
 + 
 +==== 1，Installing using Arduino IDE ==== 
 + 
 +we first need to install version 1.8.19 of the Arduino IDE (or greater),for example, the Arduino 
 + 
 +installation was in “**C/Programs(x86)/Arduino**”. download release link: 
 + 
 +[[https://downloads.arduino.cc/arduino-1.8.19-windows.exe|https://downloads.arduino.cc/arduino-1.8.19-windows.exe]] 
 + 
 +2，This is the way to install Arduino-ESP32 directly from the Arduino IDE. 
 + 
 +Add Boards Manager Entry 
 + 
 +Here is what you need to do to install the ESP32 boards into the Arduino IDE: 
 + 
 +=== （1） Open the Arduino IDE. === 
 + 
 +===   === 
 + 
 +{{:developmentboard:1.png}} 
 + 
 +=== （2）Click on the File menu on the top menu bar. === 
 + 
 +=== （3）Click on the Preferences menu item. This will open a Preferences dialog box. === 
 + 
 +{{:developmentboard:2.png}} 
 + 
 +=== （4）You should be on the Settings tab in the Preferences dialog box by default. === 
 + 
 +=== （5）Look for the textbox labeled “Additional Boards Manager URLs”. === 
 + 
 +=== （6）If there is already text in this box add a coma at the end of it, then follow the next step. === 
 + 
 +=== （7）Paste the following link into the text box ： === 
 + 
 +Stable release link: [[https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json|https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json]] 
 + 
 +Development release link: [[https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_dev_index.json|https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_dev_index.json]] 
 + 
 +=== （8）Click the OK button to save the setting. === 
 + 
 +The textbox with the JSON link in it is illustrated here: 
 + 
 +{{:developmentboard:3-3.png}} 
 + 
 +=== (9) In the Arduino IDE click on the Tools menu on the top menu bar. === 
 + 
 +=== (10) Scroll down to the Board: entry === 
 + 
 +=== (11) A submenu will open when you highlight the Board: entry. === 
 + 
 +=== (12) At the top of the submenu is Boards Manager. Click on it to open the Boards Manager dialog box. === 
 + 
 +=== (13)I n the search box in the Boards Manager enter “esp32”. === 
 + 
 +=== :developmentboard:4.png === 
 + 
 +=== (14) You should see an entry for “esp32 by Espressif Systems”. Highlight this entry and click on the === 
 + 
 +=== Install button. This will install the ESP32 boards into your Arduino IDE === 
 + 
 +{{:developmentboard:5.png}} 
 + 
 +Once the installation completes, we need to select the correct board options for the "**ESP32 Arduino**" board. 
 + 
 +In the board type, in the tools tab, we choose “**ESP32S3 Dev Module**”. 
 + 
 +{{:developmentboard:6.png}} 
 + 
 +{{:developmentboard:7.png}} 
 + 
 +Set and In the programmer entry of the same tab, we choose “**esptool**”. 
 + 
 +{{:developmentboard:8.png}} 
 + 
 +It’s important to note that after the code is uploaded, the device will start to run it. So, if we 
 + 
 +want to upload a new program, wee need to reset the power of the device, in order to 
 + 
 +guarantee that it enters flashing mode again. 
 + <font 14px/inherit;;inherit;;inherit>**First program**</font> 
 + 
 +Since this platform is based on Arduino, we can use many of the usual functions. As an example for the 
 + 
 +first program, the code bellow starts the Serial port and prints “hello from ESP32” every second. 
 + <font 16px/inherit;;inherit;;inherit>**void setup() {**</font> 
 + <font 16px/inherit;;inherit;;inherit>**Serial.begin(115200);**</font> 
 + <font 16px/inherit;;inherit;;inherit>**} **</font> 
 + <font 16px/inherit;;inherit;;inherit>**void loop() {**</font> 
 + <font 16px/inherit;;inherit;;inherit>**Serial.println("hello from ESP32");**</font> 
 + <font 16px/inherit;;inherit;;inherit>**delay(1000);**</font> 
 + <font 16px/inherit;;inherit;;inherit>**}**</font> 
 + 
 +If everything is working fine, we will see the output in the serial console shown. 
 + 
 +{{:developmentboard:9.png}} 
 + 
 +Again thank you for so much concern.. Hopefully, it's the beginning of a wonderful relationship! 
 + 
 +===== Sample program usage ===== 
 + 
 +At present, only a preliminary explanation and introductory use are given to the samples displayed on 
 + 
 +the screen, and the corresponding examples in the data center are found, as shown in the figure： 
 + 
 +{{:developmentboard:10.png}} 
 + 
 +The examples in the red circle are all based on the Arduino_GFX library as the basic application. This 
 + 
 +library supports various commonly used driver chips, such as ST7735, ST7789, ILI9341, etc., and has 
 + 
 +good compatibility. Arduino_GFX library file installation: 
 + 
 +Open the library manager in Arduino, search for Arduino_GFX, and click instal . 
 + 
 +{{:developmentboard:11.png}} 
 + 
 +{{:developmentboard:12.png}} 
 + 
 +Although the Arduino_GFX library has many advantages, it may also have a troublesome place for 
 + 
 +ordinary users, that is, after the installation 
 + 
 +==== About the use of touch and LVGL ==== 
 + 
 +Find the data center 3_3-4_TFT-LVGL-Widgets 
 + 
 +=== As shown： === 
 + 
 +{{:developmentboard:13.png}} 
 + 
 +Download two library files . 
 + 
 +One -Arduino_GFX library 
 + 
 +{{:developmentboard:14.png}} 
 + 
 +{{:developmentboard:15.png}} 
 + 
 +Copy the lv_conf.h of the data center . 
 + 
 +=== As shown： === 
 + 
 +{{:developmentboard:16.png}} 
 + 
 +Put this file under the arduino library file, it must be in the same root directory as the library TFT_eSPI . 
 + 
 +=== As shown： === 
 + 
 +{{:developmentboard:17.png}} 
 + 
 +Three-Lvgl demos The file is copied to the SRC folder 
 + 
 +=== As shown： === 
 + 
 +{{:developmentboard:18.png}} 
 + 
 +After compiling, you can run LVGL and touch normally.
