USBi programmer issues (EVAL-ADUSB2EBUZ)
Hello everyone, When we started our DSP project, we got some Chinese USBi programmers with our DSP Devboards, which didn't seem to be of the best quality, so to improve our reliability we decided to b

Writing to EEPROM does not work
Hi folks, I have similar issues as described here: Issues writing to EEPROM - Was previously working. I built my own board which is in it's core similar to the 1466 eval board. The EEPROM is of type 2

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

Programming ADAU1761 using Sigma Studio Capture Window Address + Data sent from microprocessor Circuitpython via I2C
I am (usualkly) successfully able to use address and data copied from the capture window of Sigma Studio to program an ADAU1761 via I2C. I use CircuitPython running on an nRF52840-based microprocessor

ADAU1701+esp32+micropython
hi. I decided to experiment with adau1701 and esp32, wrote a simple code to turn mute on and off using micropython, ran it on a microprocessor, but it doesn't want to work. I checked the dsp address,

External Master Clock vs I2S
Using ADAU1772, we create a Master Clock with our fpga. It is a little off, 12.262 MHz. I did not change anything in the PLL SigmaStudio tab, wrote the EEPROM with the fpga, and we got the intended si

Can somebody check if my program is OK?
Hello, Could somebody check if there is an error in my program? I'm new to Sigmastudio and don't what to look for at the moment. The first time I loaded this program into my tinysine board the speaker

Much noise when connecting an I2C programmer to a ADAU1701 board .... what would be a general reason?
I have just made a new PCB with a ADAU1701, PCM1808 and 2 x PCM5102A I'm using Wondom ICP5 I2C programmer connected to RST, WP, SCL SDA and GND. When I connect the programmer to the board, I get quite

Implementing custom USBi "device" for ADAU1701 programming
Dear ADI Team, I am designing a class D amplifier that will utilize the ADAU1701 DSP. There will be an MCU with USB capabilities on the same board. That USB will be used mainly for firmware updates an

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

Unable to program DSP and Boot EEPROM on ADAU1452
We have created a new custom PCB design that uses the ADAU1452WBCPZ Sigma DSP. We are unable to program the DSP internally or program the external Boot EEPROM. We are using Sigma Studio, Ver 4.7 with

Is it possible to offload FIR processing to the RPi 4 NEON SIMD from the ADAU1701?
So my thought is this: since the Sharc came out, there have been advances in process and architecture making the number of coefficients that can be processed through NEON on ARM greatly increased over

Sigma studio for ultrasonic application
Hello ! :) Im a student in engineering, my project is to develop a directive speaker based on a ultrasonic piezo array. The audio signal should be modulated with a sine carrier (AM, DSB). The carrier

REAL programming of EEPROM through DSP in a production test environment
I've seen several posts that dance around the issue, but none seem to really get to the point. Is there a scriptable (command line preferred) tool that can write a SigmaStudio DSP image through the DS

How to programm DSP with MCU
Hello. I control ADAU1466 with PIC32 over SPI, it works well. ADAU1466 is programmed with sigmastudio, and then controlled with PIC32. But I need solution, where Sigmastudio generates hex (or other fi

Prevent poping-noise while programming
Hi ! I've had popping noise (DC) on the ADAU1466 and ADAU1701 while programming. It seems that the Soft Reset and Hibernate commands in the programming sequence are causing this. I've tried having a G

ADUSB2Z 1.4 Multi Master Programming Problem
Hello, we got a uC that communicates periodically over I2C with one ADAU1452 and we have the ADUSB2Z programmer on the same I2C. This causes problems when programming the DSP because two I2C masters a

DM1 programming problem with adau1467
Hi all, We have problem to write more than 24672 bytes to DM1. The is no problem to write larger amount by interfacing sigmastudio (4.2) directly to the dsp. But we are using an mcu to program the dsp

ADAU1701 NOP instruction 0x0000000001 vs 0xFFFFFFFFFF
Sigma Studio always tells me there are 5120 eight bit program bytes (1024 forty bit instructions) when clearly many are simply NOP's. (in my case more then 1/2 are NOP's.) So, in order to conserve spa
