The video demonstrates using this kit to stream audio from a laptop and drive it to the speakers, using the kit as a simple voice recorder, and using the kit to sample any audio source with a headphone jack (e.g., a cell phone) and play the audio over the speakers — all using standard functions on the microcontroller.
Adding Sound to Embedded Designs
See how to easily add Utility Class D audio to embedded designs using the Silicon Labs Class D ToolStick, featuring Precision32 SiM3C1xx and SiM3U1xx 32-bit microcontroller devices. This demonstration and development board acts like an Audio Class Device, allowing you to send data to the speakers using Utility Class D audio.
