GUI Display

Example Brief

This example demonstrates how to use the LVGL graphics library to draw a music player user interface that supports touch screen control. This example refers to the original LVGL lv_demo_music project.

Environment Setup

Hardware Required

This example runs on the boards that are marked with a green checkbox in the table. Please remember to select the board in menuconfig as discussed in Section Configuration below.

Build and Flash

Default IDF Branch

This example supports IDF release/v4.4 and later branches. By default, it runs on IDF release/v4.4.

IDF Branch

  • The command to switch to IDF release/v4.4 branch is as follows:
cd $IDF_PATH
git checkout master
git pull
git checkout release/v4.4
git submodule update --init --recursive

Configuration

The default board for this example is ESP32-S3-Korvo-2 v3.

Build and Flash

Build the project and flash it to the board, then run monitor tool to view serial output (replace PORT with your board's serial port name):

idf.py -p PORT flash monitor

To exit the serial monitor, type Ctrl-].

For full steps to configure and build an ESP-IDF project, please go to ESP-IDF Programming Guide and select the chip and version in the upper left corner of the page.

How to Use the Example

Example Functionality

After the example starts running, it first presents the welcome page. Then, after entering the play page, please swipe up ALL TRACKS to see the playlist. Click on a piece of analog music, then slide down the collapsed play page to see the music being played.
