Running the Sample Demo

Using SigmaStudio+ the A2B system can be directly controlled from a connected computer without involving a microcontroller or a DSP. This mode is helpful for quick testing of the capabilities of AD24xx without the need for a microcontroller in the system.

Note: Please refer Appendices A and B for information about navigating in SigmaStudio+ for A2B use-case.

A block diagram of a 3 node A2B system with PC as Host is shown in Figure 43.

The sample demo configuration is as shown in Figure 44. The audio source connected to sub-node 1 will be played out at main node. The microphone audio from sub node 0 will be played out at sub node 1.

The sample demo configuration can be run with either EVAL-AD2428WD1BZ, ADZS-21569 EZ-KIT, EVAL-AD2433WA1BZ , EVAL-AD2435WA3LZ, EVAL- AD2430WD1BZ or EVAL-AD2438WD1BZ, EVAL-AD2437A1NZ as the A2B main platform. The following sections describe the procedure for running the demo.
