A2B audio

Category: Software
Product Number: AD2428
Software Version: adi_a2b-ssplus_software-rel1.3.2

Hello ADI Team,

I am currently working with the following A²B evaluation boards:

  • EVAL-AD2428WD1BZ – Main Node
  • EVAL-AD2428WG1BZ – Subordinate Node

I am trying to create a simple A²B setup where the WD1BZ is the Main Node and the WG1BZ is the Subordinate Node, and I would like to run a basic stereo audio example between the two boards using SigmaStudio+.

However, I have encountered the following issues:

  1. In the A²B SigmaStudio+ plugin/demo projects, I cannot find an example project that uses both EVAL-AD2428WD1BZ and EVAL-AD2428WG1BZ.
  2. I also cannot find EVAL-AD2428WG1BZ as a predefined subordinate platform in the plugin package.
  3. Therefore, I created a custom subordinate platform and selected the AD242x A²B transceiver, but I am not sure whether this is the correct procedure or whether additional board-specific configuration is required.
  4. I would like to know how the WG1BZ board should be configured as a custom subordinate platform and what settings need to be added for its TDM/audio configuration, GPIO, clock, interrupts, etc.
  5. I also want to know whether there is an official sample/demo project for a WD1BZ Main + WG1BZ Subordinate setup, or whether I need to create the complete project manually.
