DSP Readback is not working

I downloaded SigmaStudio+ 2.4.0 and DSP Readback is working fine with my hardware. I connected both ADC_0 and ADC_1 with readbacks before and after the 14-bit shift and turned on continuous read. The values each tracked the potentiometers on the REVBZ.

I was also able to verify my custom PCB using a Pulse oscillator and continuous DSP Readback. I only have one LED on my board, and I need to figure out how to drive it from an MPx pin, but at least the readback shows life.

I do not see any utility to trying I2C mode with SigmaStudio 4.7 after verifying that my hardware works. There is either something wrong with SigmaStudio 4.7, or perhaps I wired things incorrectly in that project.

Note that SigmaStudio+ 2.4.0 does not have a template for the REVBZ, so I used the MINIZ, and it obviously worked fine. My board is based on the ADAU1463, and 2.4.0 only has the ADAU1466, but it seems to work fine. I assume that the newer version of SS+ 3.3.0 has the information for the ADAU1463 and REVBZ, but I'll start another Q&A for support on that.

Yes, if your hardware is working fine with SS+ then the problem earlier should either a wiring problem or project corruption in SS4.7.

please see in the hardware schematics that which MP pin is connected to the LED, and go to register section>MULTIPURPOSE>MPx tab and config it as MP pin and set it as output.

The REVBZ and MINIZ are just hardware revisions, and sigma studio DLL for 1452 is common for all. For configuring MP pins, etc. you have to look at the hardware schematics and config it accordingly in the software. Choosing REVBZ/MINIZ/ADAU1467Z/1466Z in the SS will NOT pre-config anything for that particular hardware revision, the software is just the same as the fresh custom project with the same chip.

ADAU1463 DLL is available in 2.4.0 and previous versions.
