Hi,

I am trying to control the ADAU1452 dsp with ADI SC589 via i2c writings on A2B.

I am able to write and read registers and memory of the adau1452.

I want to read certain memory addresses in the adau1452 and use the data written there to control my sigma studio project, for example enable a processing flow depending on the value written in address 0x6102.

Is it possible? do I need to write custom block using the Algorithm designer to do that?

A2B stack version: 19.3.1.

Sigma Studio version: 4.6.

Thanks for the help.

Hello Sagis,

Please find the attached project which has two examples.

One is to read a particular parameter's value (instead of address, eventually it's the same) and use it in the schematic for logic implementation and other processing.

Another one is to read a control register and make the value available in the schematic for logic implementation and further processing.
