xCORE VocalFusion Stereo Dev Kit on a Raspberry Pi

The XMOS xCORE VocalFusion Stereo Dev Kit provides far-field voice capture using the XMOS XVF3500 voice processor.

Combined with a Raspberry Pi, this kit allows you to quickly prototype and evaluate VocalFusion Stereo.

This repository provides a simple-to-use automated script to configure the Raspberry Pi to use the xCORE VocalFusion Stereo Dev Kit for audio.

Prerequisites

You will need:

• xCORE VocalFusion Stereo Dev Kit: XK-VF3500-L33
• Raspberry Pi 3
• Micro-USB power supply (min. 2A)
• MicroSD card (min. 16GB)
• Powered stereo speakers with audio 3.5mm analogue plug
• Monitor with HDMI input
• HDMI cable
• Fast-Ethernet connection with internet connectivity

Hardware and Raspberry Pi audio setup

Setup your hardware by following the Hardware Setup at: https://xmos.com/vocalfusion-stereo

Full instructions on configuring the Raspberry Pi to use the xCORE VocalFusion Stereo Dev Kit are detailed in the Getting Started Guide available from: https://xmos.com/vocalfusion-stereo.

Brief instructions and additional notes are below:

1. Install Raspbian Stretch on the Raspberry Pi. Note: This setup script is incompatible with earlier versions of Raspbian.

2. Open a terminal on the Raspberry Pi and clone this respository:
   cd ~; git clone https://github.com/xmos/vocalfusion-stereo-setup

3. Run the installation script: source ~/vocalfusion-stereo-setup/auto_install.sh Wait for the script to complete the installation. This can take several minutes.

4. Enter sudo reboot to reboot the Raspberry Pi and complete the audio setup.

You are now ready to start evaluating the VocalFusion Stereo Kit.
