lvgl-music-player

Wraps the upstream lv_demo_music() — album-art carousel, time slider, track list, equaliser visualiser. Pairs the LVGL UI with the SDK's audio chain (<alp/i2s.h> + a WM8960 codec).

Source: examples/lvgl-music-player/.

What it shows​

  • LVGL renders the player UI on a 240×320 ST7789 panel.
  • The WM8960 codec is configured via I²C (the wm8960 chip driver handles the register writes) and streams audio via I²S (host I²S0 → codec → headphone out).
  • The MP3 decoder (minimp3 from the §D.lib batch) supplies PCM frames to the I²S sink.

Hardware needed​

  • E1M-AEN family SoM.
  • E1M-EVK carrier with the audio breakout board.
  • 240×320 ST7789 TFT.
  • Headphones plugged into the codec's HP output.
