CrowPanel Advance 4.3inch ESP IDF Course V13

# CrowPanel Advance 4.3-Inch HMI ESP32-S3 Screen ### ESP-IDF Course Guide **800 x 480 IPS Touchscreen | ESP32-S3 | ESP-IDF | V1.3** ---

Product Model: CrowPanel-Advance-4.3-HMI-ESP32-S3-AI-Powered-IPS-Touch-Screen
Hardware Version: V1.3
Number of Lessons: 5 lessons
Development Platform: ESP-IDF v5.5.4 + ESP32-S3
Learning Path: ESP-IDF Environment Setup -> HTTP MP3 -> LVGL LED -> DHT20 Temperature and Humidity Display -> SD Card BMP Image Display

1. Course Overview

This course is designed for the CrowPanel Advance 4.3-Inch HMI ESP32-S3 Screen V1.3 and uses native ESP-IDF projects for development. The course starts with ESP-IDF development environment installation and serial port verification, then covers HTTP MP3 network audio playback, LVGL LED control, DHT20 temperature and humidity data acquisition and display, and reading BMP images from an SD card for on-screen display.

The 4.3inch version uses an 800 x 480 IPS touchscreen and ESP32-S3. It is designed for AI HMI and smart touchscreen applications, and is suitable for learning how to integrate large-format display, audio playback, sensor acquisition, and storage-based display features in native ESP-IDF projects.

The ESP-IDF course content and lesson links are shared across the 4.3-inch, 5.0-inch, and 7.0-inch versions. This guide focuses on the 4.3inch V1.3 version.

Study in order from Lesson 01 to Lesson 05:

  1. Development Basics: In Lesson 01, first complete ESP-IDF v5.5.4 environment installation, target chip esp32s3 configuration, serial port connection, build, and flashing verification.
  2. Audio Features: In Lesson 02, learn the HTTP MP3 network audio playback workflow and understand audio playback tasks and peripheral initialization in ESP-IDF projects.
  3. Display and Touch: In Lesson 03, learn how to use display, touch, LVGL 9.1.0, and LED control together.
  4. Sensor Display: In Lesson 04, learn how to read the DHT20 temperature and humidity sensor and update the data on the LVGL interface.
  5. Storage and Image Display: In Lesson 05, learn how to read BMP files from an SD card and display images, laying the foundation for future graphical interface projects.

**First complete ESP-IDF environment verification, then gradually study audio, LVGL, sensors, and SD card display to build a foundation for ESP-IDF development on the 4.3inch HMI screen.**
