1. Course Overview¶
This course is designed for the CrowPanel Advance 2.8-inch HMI ESP32-S3 Display V1.2 and uses Arduino IDE as the development platform. The course starts with serial output verification and gradually covers network audio playback, PWM and LVGL light control, SD card image slideshow, DHT20 temperature and humidity display, nRF24L01 communication, LoRaWAN AT parameter control, Zigbee light control, and microphone recording and playback.
The 2.4-inch and 2.8-inch displays both have a resolution of 320 x 240, and they share the same Arduino course content and lesson links. This guide focuses on the 2.8inch V1.2 version.
After completing this course, users will understand the basic development workflow for this display on the Arduino platform and will be able to build their own HMI applications based on display, touch, audio, sensor, and wireless modules.
2. Preparation Before You Start¶
- Hardware: CrowPanel Advance 2.8-inch HMI ESP32-S3 Display V1.2
- USB Cable: Use a USB cable that supports data transfer
- Development Software: Arduino IDE
- Getting Started with Arduino IDE: https://www.elecrow.com/pub/wiki/arduino_advance.html
- Board: ESP32S3 Dev Module
- Flash Size: 16MB (128Mb)
- PSRAM: OPI PSRAM
- Partition Scheme: Huge APP (3MB No OTA/1MB SPIFFS)
The board package must use esp32 by Espressif Systems version 3.3.8.
3. Library Version Requirements¶
The course documentation requires that you first import the required course libraries according to the instructions in Lesson 01 and keep the library files consistent with the screen size. The 2.4 / 2.8-inch Arduino courses share the same library files:
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 by Lesson 01/03/09/10 |
| lvgl | 9.1.0 | LVGL UI and SquareLine Studio exported projects |
| LovyanGFX | 1.2.25 | Arduino graphics display and screen driver |
| TAMC_GT911 | 1.0.2 | Touchscreen support library |
| ESP32-audioI2S-master | 2.0.0 | Network audio playback |
| RF24 | 1.6.1 | nRF24L01 wireless communication |
| RadioLib | 7.1.0 | Wireless module support related to LoRaWAN AT parameter control |
| Crowbits_DHT20 | Use the course-provided library files | DHT20 temperature and humidity sensor |
| lv_conf.h | Use the course-provided configuration file | 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: Use LVGL 9.1.0 for LVGL projects. 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 board package, you need to replace the corresponding files in the ESP32 framework directory. Download the officially provided ESP32S3_120M files:
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 with the ESP32 Core version. 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, which helps improve display refresh performance and reduce flickering or jitter during operation.
