M5Mp3 Winamp Player for Cardputer-Adv (video)

M5Mp3 Winamp Player for Cardputer-Adv - Video Description Projec Overview This video demonstrates a fully functional Winamp-style MP3 player running on the **M5Stack Cardputer-Adv**. The project is an adaptation of the original M5Mp3 by VolosR, completely rewritten to work with the Cardputer-Adv's ES8311 audio codec and built-in display. * GitHub Repository:* https://github.com/AndyAiCardputer/mp... *Original Project:* [VolosR/M5Mp3](https://github.com/VolosR/M5Mp3) What You'll See *Classic Winamp Interface* - Authentic retro look with animated visualizer *MP3 Playback* - Smooth audio playback from SD card *Full Controls* - Play/pause, next/previous track, volume, brightness *File Browser* - Scroll through your music collection *Battery Indicator* - Real-time battery level display *Visual Equalizer* - Animated bars that react to music Technical Highlights Audio System *ES8311 Audio Codec* - Native support via M5Cardputer.Speaker API *ESP8266Audio Library* - MP3 decoding with custom AudioOutput class *Triple Buffering* - Smooth playback without glitches *Stereo to Mono Conversion* - Optimized for Cardputer-Adv's mono output Display & Interface *240x135 Built-in Display* - Perfect for the Winamp interface *FreeRTOS Multi-tasking* - Separate tasks for display and audio *Smooth Animations* - 25 FPS display updates *Scrolling Track Names* - Long filenames scroll automatically Key Adaptations Replaced ESP32-audioI2S with ESP8266Audio Created custom AudioOutputM5CardputerSpeaker class Removed I2S pin configuration (uses ES8311 API instead) Replaced ESP32Time with simple millis() timer Added MP3 file filtering Hardware Requirements M5Stack Cardputer-Adv microSD card (FAT32 formatted) MP3 files Controls *A* - Play/Pause *N* - Next track *P* - Previous track *V* - Volume up (cycles: 5→10→15→20→5) *L* - Brightness control *B* - Random track *ENTER* - Restart current track *;* / *.* - Scroll through file list Code Structure The project uses FreeRTOS tasks running on different CPU cores: *Task_TFT* (Core 0) - Handles display updates and keyboard input *Task_Audio* (Core 1) - Manages MP3 decoding and playback Audio pipeline: SD Card → AudioFileSourceSD → AudioFileSourceID3 → AudioGeneratorMP3 → AudioOutputM5CardputerSpeaker → M5Cardputer.Speaker (ES8311) Installation 1.
