Does SigmaDSP perform SCLK stretching for timing sync with USBi?
After some reliability issues with SigmaStudio ReadBack (both EVAL and custom hardware, alike), I am looking at the USBi bus in SPI mode with a logic analyzer, and it appears that the SigmaDSP might b

ESP32 SPI control of ADAU1467 parameter RAM on EVAL-ADAU1467Z — writes not taking effect
I'm trying to control an ADAU1467 on the EVAL-ADAU1467Z evaluation board from an ESP32 microcontroller via SPI on the J1 slave control port header (the same header used by the USBi). Setup: EVAL-ADAU1

Rasp Pi SPI Initial Settings
I am doing initial interface to a R-pi using J1 on the board. MISO, SS, MOSI, and SCLK are all verified. Can't seem to establish com with the board and read the registers. Couple questions. 1) Do I ne

Which Registers control SPI Mode and other configuration?
The datasheet warns that "The master port must be reconfigured in software before using a protocol other than the one configured at boot time." So, how is this done? Which Registers control this confi

What is SPI mode CPOL CPHA for ADAU1701?
There seems to be quite a bit of confusion over ADAU1701 and SPI mode. What is it?! This post seems to indicate it's SPI mode 0 (CPOL=0 CPHA=0), RE: ADAU1701 SPI mode This says (not specifically about

Read from ADAU1761 over SPI
Hello EZ Community, I am trying to setup the ADAU1761 using SPI on our prototype board. So far I’ve had no success setting it up or reading from it. Initially i tried reaching out to technical support

How to send my data from SPI
HI I want to connect display to adau1467 via SPI. This information also will be useful for future designs to connect different 3rd parity chips. So let's say. I want to send "0A 12 B0" data from Spi p

Reset RAM via MCU
Hey Team, Is there a way to clear the DSP RAM via SPI from a MCU ? The datasheet says that after a hardware reset the RAM is not guaranteed to be cleared. I implemented a DSP firmware update mechanism

SPI Master Interface Bitrate
Hey together, I have a question regarding the bitrate of the SPI Master Control Port. We have an EEPROM connected to the SPI Master Control Port to store some user data and this works fine. But we not

Control two different devices and selfboot EEPROM with USBi
Hello, For a dual-DSP project i want to use two different ADAU1466 on one PCB, each equipped with an EEPROM for selfboot functionality. I'd like to program both of them via SPI through one USBi progra

Connecting SPI peripherals to read back data from DSP
I am new to SigmaDSP so I apologize if I am overlooking something obvious here. For testing I have the ADAU1467 eval board connected via USBi to the PC. I want to simultaneously get some data/values f

External SPI Delay with SRAM
Dear, We use the ADAU1467 and have need a audio delay of more than 1 sec for at least 8 channels (max 12 channels). The sample rate is 48Khz at 24 bits. I will have a rate of 48Khz sps * 24 bit * 12 =

Write Biquad Coefficients through SPI
Hello, After uploading the schematic shown in the photo to the ADAU1467z, I exported the file and set it up to be remotely controlled via a Teensy 4.0. I used an SPI connection, and I confirmed that t

External SPI Delay on multiple channels shared with SRAM?
Dear ADI community, I'm currently planning to build an algorithm/architecture for the ADAU1466 where each of 8 outputs gets the option to set up to pretty high delay at 96 kHz (up to 1 second per chan

How do I modify this 2way project file to get the SPIDF output working on my HiFiBerry Beocreate 4ch amplifier?
I really need help on this or my boombox project is dead in the water! Here is a link to the 2-way project file I downloaded from HiFiBerry: https://www.hifiberry.com/wp-content/uploads/2017/10/2-way-

Controlling SigmaStudio Cell via SPI Slave
Hello, I am planning to interface a ADAU1452 with a STM32 via SPI. I am currently programming the ADAU1452 with Sigmastudio via USBi. However, for my Project I need to control the volume of the ADAU14

Confusion About E2PROM and MCU
I'm trying to integrate the ADAU1702 into a project and I'm experiencing some confusion about how a permanently connected MCU and E2PROM are meant to interact, if at all. Do I need an E2PROM if I'm us

How to write volume value from spi-connected Arduino to safeload?
Hi. My problem is that I shut down the power using push volume on adau1466 When turned on, the volume is initialized (interface read, write does not work) So, by connecting Arduino Nano with SPI, I wa

sigmadsp_fwgen for ADAU1466
Hello, For a few years now we have a system with an embedded Linux that transmits through SPI the firmware to an ADAU1452 DSP. The firmware is made from the exported .xml then transformed with the sig

ADAU1452 suitable SPI EEPROMs
I want to go with a bigger EEPROM than what is used in the EVAL board to be safe with large FIR filters. I cannot find much information about which specifications to look for. I thought 25CSM04T-I/SN

Setup a software controlled DAC/ADC through i2c with ADAU1466
Hi everybody, I'll detail the board as much as I can: So, the board have a ADAU1466, 4x PCM5122 and 1x PCM1865, both ADC and DAC are software controlled through i2c, with its respective addresses corr

External SPI delay for long delays
Hello, I have a PCBA with an ADAU1401 performing some ADC-DSP-DAC tasks and it works pretty fine. now I need to add a big delay to the audio, so I came to the possible solution of codec+DSP. I am tryi

ADAU1452 SPI RAM
HI team. So I bought Adau1452 custom board from China, I am sure this board is common for now. Most of the function is normal. selfboot is also normal. No problem so far. But, I want to do the SPI del
