DECA USB Audio Interface

DECA based USB 2.0 High Speed audio interface

Status / current limitations

  • enumerates as class compliant audio device on Linux and Windows.
  • Works on the FPGA
  • Playback works
  • Recording works
  • only 48kHz sample rate supported
  • integrated USB2 high speed logic analyzer works

support

In the release section I provide a .sof file (for directly programming the board) and a .pof file (for flashing the device), for convenience. Saves you from building the project yourself, if you do not want to.

If you encounter issues building this project, I recommend reading this article: http://retroramblings.net/?p=1718
