This is a project that will be developed in parallel with the procyon development board. We currently plan to use a permissive license for this project.
The goal is to create a fully modular reference HiFi stereo digital music player.
There will be the following boards:
- Processing (Procyon based)
- User Interface
Here are the rough block diagrams for how the modular system concept is at this time, you can of course replace any board you wish:
The goal is a player that will play codecs useful for stereo music reproduction the goal implementation order is:
- WAV/RIFF and similar
- FLAC with cue sheets
Patented formats are unlikely due to royalties.
The project depends on linking to a port of ffmpeg's FLAC decoder (LGPL library)
DAC board WM8740 based - Version 1 Done
Firmware - USB mass storage, FLAC and WAV output for 44.1 KHz/16-bit
Firmware add library management system
Firmware user interface spec (UART controlled)
User interface board design
Improve DAC board (?)
Power supply board design …
