Setting Up

Most software platforms have integrated Tone1 Drivers. Only Windows platforms need to install drivers.

Make sure the firmware of your VIM1 is upgraded to VIM_Nougat_V180524 or later.
Make sure the firmware of your VIM2 is upgraded to VIM2_Nougat_V180413 or later.
Edge-V TBD.

We will use Windows 10 for this example. Windows 7 is similar.

FAQs

  • How to extend to 8-channel audio?
    XMOS supports 8-channel analog line-out. However, the Tone1 DAC (ES9038Q2M) is already using 2-channels. Users can add a DAC for 8-channel expansion.
