Some demo projects for ESP32-Elite Board

ESP32-Elite is a development board based on LCKFB ESP32S3 core for beginners and to explore the capabilities of the ESP32 platform.

The following is a picture of the board with modules installed:

and a picture of the board with modules removed:

The demos are designed to be used with the PlatformIO extension in VSCode, allowing users to easily upload code to the board and interact with it.

Getting Started

0. Install the PlatformIO extension in VSCode
1. Open one of the demo projects in VSCode
2. Upload the code to your ESP32-Elite board
3. See what happens!

Available Demos

• Demo 0: Hello World

  • A simple demo that blinks the onboard LED, prints a counter value to the Serial Monitor and echoes messages received from the Serial Monitor.

• Demo 1: Buttons and LEDs

  • Demonstrates how to use buttons, control LEDs on the ESP32-Elite board and print messages to the Serial Monitor when buttons are pressed.

• Demo 2: ADC

  • Demonstrates how to read analog values from the potentiometer, display them on the Serial Monitor and create a task to control the LED blinking rate based on the potentiometer position.

• Demo 3: RGB

  • Demonstrates how to control an WS2812 RGB LED using the Adafruit_NeoPixel library and change its color based on button presses detected by interrupts.

• Demo 4: IMU

  • Demonstrates how to use the onboard IMU (Inertial Measurement Unit) LSM6DS3 to read acceleration and gyroscope data, and print the values to the Serial Monitor or visualize the attitude using the Teleplot extension in VSCode.

• Demo 5: Audio

  • Demonstrates how to play audio files from the SPIFFS filesystem using the Audio library and control playback using buttons on the ESP32-Elite board.

• Demo 6: Matrix

  • Demonstrates how to control a 8x8 LED matrix using the U8G2 library, displaying a scrolling text message.

• Demo 7: MIC

  • Demonstrates how to use the onboard digital microphone to capture audio data to control the count of LEDs based on the sound level detected by the microphone and print the sound level to the Serial Monitor which can be visualized using the Teleplot extension in VSCode.

• Demo 8: LCD Simple

  • Demonstrates how to use the onboard LCD display to show simple text messages and control the display using buttons on the ESP32-Elite board.

• Demo 9: LVGL-LED-ADC

  • Demonstrates how to use the LVGL library to create a simple GUI that displays the current value of the potentiometer and allows control of LEDs using checkboxes with input from the buttons.

• Demo 10: LVGL-Spectrogram

  • Demonstrates how to create a simple audio spectrum analyzer using the LVGL library, displaying the audio levels captured from the onboard microphone in a graphical format.
