ADAU1466_Sigmastudio4.7_Memorypage_Question
I have a question regarding the use of ADAU1466 with SigmaStudio 4.7. In my design, I'm using PM Upper, and the exported .xml file shows: <Program> <Name>PM Lower</Name> <Address>49152</Address> <Addr

Group different read values into a contiguous memory space
Hi, I need to read with i2c 3 different values located at different memory addresses. To facilitate the synchronization of the data, I want to be able to read these 3 values in one i2c read. How can I

Delay problems 1701 DAKB4100
Hi guys. Im new to using the SigmaDSP and I am using with the Dayton Audio KABD 4100 board which uses the 1701 DSP. And i am having huge trouble with the delay function. I understand that the only way

Reading parameter data on ADAU1701 via microcontroller
I'm aware that the standard way for reading data from the ADAU1701 is via readback cells. But can I read parameter data I've written, just with I2C memory access? For example, if I safeload write a ga

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

How to configure access to the ADAU1787 memory as read-only after booting up?
I would like to make sure the memory is protected from writes after it is configured properly during boot. Is there a register sequence to lock/unlock memory writes? Thanks.

ADAU1466 second page addressing
Hi all, We are implementing the interface for controlling an ADAU1466 from an MCU and we've found that the second page addressing is quite inconvenient. This is because the addresses of parameters tha

ADAU1701 - Exported system files are way too big
When exporting system files for my SigmaStudio code, the compiler of course knows the data and parameter RAM utilized by my code, but when the system files are exported, the arrays for the program and

ADAU1452 memory limit
Dear AD techs, i have a quite large project going on and i'm almost at the end of developing. Actually total PM used is around 7200 and i noticed that if i further add cells my program starts to have

WRITEBACK in ADAU1452/67/63
How to do writeback in ADAU1452/67/63 chips? There is hint in http://www.analog.com/media/en/technical-documentation/user-guides/EVAL-ADAU1467Z-UG-1134.pdf But I am unclear how to configure the chip t

Cell settings of delay block
I'm booting and controlling an ADAU1452 with an 8bit microcontroller. In sigma studio I try to exclude RAM content of all delay-cells from export (see file "*_04A_IC_1.h") in order to keep the exporte

ADAU1701 and EEPROM memory
Hello guys. Please excuse me for the somewhat dumb question, i am really new to SigmaDSP and my kit has not arrived yet. I am designing a device with the ADAU1701 in self boot mode with a MCU that wil

ADAU1452 DM0 delay issue
There is a problem in the way sigmastudio allocate DM0 memory for DM0 delays. Here is an example schematic: It's a simple DM0 delay and a simple DM1 delay. Here is the modified and commented compiler_

ADAU1701 Instruction Usage Table
Several designers have recently asked about how to estimate instruction usage by various algorithms on the ADAU1701, since its compiler does not itemize instruction usage by individual blocks. The att

Can I write to the SigmaDSP RAM in byte-by-byte fasion? (i.e. One byte per write?)
My microcontroller's I2C or SPI write function can only write a single byte at a time. How can I write to the SigmaDSP's memory? i2c memory spi control_port ram
