I2S example


This is a simple I2S audio transceiver example. You can plug any source of music and listen to it.

Audio Format

The driver requires and provides Audio data with the following parameters:

  • 44100 kHz sample rate

  • Signed 24 bit PCM

  • Stereo

  • Little endian


mkdir build && cd build
cmake -DBOARD=litex_vexriscv ..

Known issues

It seems that after a few minutes some music delay occurs, this is because the sound driver is not able to send data as fast as it receives it.
