How to configure the ADAU1452 signal processing on the EVAL-AD2437A1NZ
Using SigmaStudio+, I connected two EVAL-AD2437A1NZ boards via USBi, configuring one as Main and the other as Sub. The connection is established correctly. The EVAL-AD2437A1NZ Manual states that Sigma

Port0 (or Port1 out) be the clock master and Port1 input be a slave without physically wiring the clock pins between them — i.e. let the DSP sync internally?
Hi I am using below setup - Serial Output port -1 as master - LRCK_OUT1 & BCLK_OUT1 are connected to codec - SDATA_OUT1 driving 2ch (I2s) data to codec (SDATA_OUT1 --> CODEC_DIN) Now i am trying to re

Continuous READBACK polling over I2C is it safe for the sigma core?
Hi, I’m using an ADAU1701 controlled by an ESP32 via the I2C interface (currently set to 400 kHz). The ESP32 loads the full program into the DSP and communicates with it in real time, reading data fro

SigmaDSP running 32kHz - no interface support
Hi, I want to run the SigmaDSP in 32kHz sample rate as I'm running out of MIPS. 24kHz samplerate is too low signal bandwidth. Is that posible? I can select it in the SigmaStudio, but I can't select it
