Hardware Version: V1.5
Number of Lessons: 9 lessons: Lessons 1-7, Lesson 9, and Lesson 10
Development Platform: Arduino IDE + ESP32-S3
Learning Path: Environment Setup -> Timed Serial Output -> WiFi Audio -> LVGL Desk Lamp Interface -> SD Image Display -> Sensors -> Wireless Communication -> Microphone Recording and Playback
1. Course Overview¶
This course is designed for the CrowPanel Advance 7.0-Inch HMI ESP32-S3 Screen V1.5 and uses the Arduino IDE as the development platform. The course starts with timed serial output verification, then gradually covers WiFi audio playback, an LVGL desk lamp control interface, SD card image slideshow, DHT20 temperature and humidity display, nRF24L01 communication, LoRaWAN AT command control, Zigbee light control, and microphone recording and playback.
The 7.0inch version uses an 800 x 480 IPS touchscreen and ESP32-S3. It is designed for AI HMI and smart touchscreen applications, making it suitable for learning large-screen human-machine interaction, audio playback, sensor data acquisition, image display, and wireless module expansion development.
The 4.3-inch, 5.0-inch, and 7.0-inch screen courses share the same course content and course links. This guide focuses on the 7.0inch V1.5 version.
After completing this course, users will understand the basic development workflow for this screen on the Arduino platform and will be able to expand their own HMI applications based on large-format display, touch, audio, sensors, and wireless modules.

The development board package must use esp32 by Espressif Systems version 3.3.8.
3. Library Version Requirements¶
The course documentation requires you to first import the required course library files according to the instructions in Lesson 01, and to keep the library files consistent with the screen size. The 4.3 / 5.0 / 7.0-inch Arduino courses share the following libraries or components:
Library Import: Link to two ways to import third-party Arduino IDE libraries
| Library / Component | Version / Source | Purpose |
|---|---|---|
| esp32 by Espressif Systems | 3.3.8 | ESP32-S3 Arduino Core, explicitly required in Lesson 01/03/09/10 |
| lvgl | 9.1.0 | LVGL UI and SquareLine Studio exported projects |
| LovyanGFX | 1.2.25 | Arduino graphics display and RGB screen driver |
| TAMC_GT911 | 1.0.2 | Touchscreen support library |
| ESP32-audioI2S-master | 3.4.7 | WiFi audio playback |
| RF24 | 1.6.1 | nRF24L01 wireless communication |
| RadioLib | 7.7.1 | Wireless module support related to LoRaWAN AT command control |
| Crowbits_DHT20 | Use the library file provided with the course | DHT20 temperature and humidity sensor |
| lv_conf.h | Use the configuration file provided with the course | LVGL configuration file |
| ESP_I2S.h | Built into Arduino-ESP32 3.3.8 | Microphone recording and audio playback |
| Wire / SPI / FS / SD | Built into Arduino / ESP32 Core | I2C, SPI, file system, and SD card |
Note: For LVGL projects, use LVGL 9.1.0. When creating a project in SquareLine Studio, you also need to select LVGL 9.1.0 and set the LVGL Include Path to lvgl.h.
4. ESP32S3_120M Notes¶
After installing the ESP32 development board package, you need to replace the corresponding files in the ESP32 framework directory. Download the officially provided ESP32S3_120M file:
Copy the files in the ESP32S3_120M folder to the corresponding idf-release_* directory in the Arduino ESP32 framework, and replace the existing files when prompted. The directory name changes depending on the ESP32 Core version, so use the actual directory for esp32 by Espressif Systems version 3.3.8 installed on your computer:
C:\Users\your-username\AppData\Local\Arduino15\packages\esp32\tools\esp32-arduino-libs\idf-release_*
ESP32S3_120M contains ESP32 framework files recompiled after enabling high-speed PSRAM communication mode. After replacement, the PSRAM frequency can be increased to 120 MHz, helping improve the display refresh performance of large screens and reduce flickering or jitter during operation.
