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.
A block diagram of a 3 node A2B system with PC as Host is shown in Figure 43.
Figure 43: A2B system with PC as Host
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.
Figure 44: Sample A2B demo configuration
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.
Refer section Sample Demo Setup for sample demo using EVAL- AD2430WD1BZ or EVAL-AD2438WD1BZ
Refer section Sample Demo Setup with PC for sample demo using EVAL – AD2437WA1NZ and AD2437B1NZ.
