Using additional ADAU1466 core for added DSP resources for higher order ANC
Hello again, I'm back with a new question. I've attached a block diagram of what I'm attempting. basically I'm trying to use an additional ADAU1466 core to add DSP resouces because I want to use longe

How to properly use DC Input Entry
Hi, I want to use DC Input Entry to index ISF. So, if I'm using 1467 - 32bit, according to AD Wiki I need to use integer value for ISF: 32.0 But before that I wanted to debug input value with a Readba

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

ReadBack Parameter Issue
Hello, I am trying to use "ReadBack Parameter" block in my ADAU1787 in order to obtain the FIR coefficients of a NLMS block. These coefficients will be used later on a FIR filter to compensate the sec

Interface Read / Write ADAU1467
Hello together, we have a question about the Master Control Port Interface Read and Write. Our requirement is that we need to store some values, which are set during runtime of the ADAU1467, persisten

Tone control implementation
I, too, am trying to implement a simple tone control. The strategy described here, using indexed filters, seems very straightforward, but it hasn't worked in my hands. As best I can tell, I have the c

Fixed register address at pre-compile stage possible?
Hi, I'm wondering if it is possible to "set" a register address at pre-compile stage. E.g.; When I compile my SigmaStudio program for an ADAU1452, compiler sets the address of a readback register to 0

Parameter readback and update not working?
Hello, I am having an issue while working with mij EVAL-ADAU1787Z board in SigmaStudio. I am trying to change the gain value of a gain block using a Parameter Update block. Something that looks like i

Multiplication doesn't work
Hi, I just read the article about number formats in Sigma DSP and also about the readback function, which can only display a 24.0 number format and thus truncates the last 4 bits of the input value. S

[Bug Report] SigmaStudio / Eval ADAU1787Z incorrect parameter names; Real Time Parameter read values and addresses
See the attached project file. I used the Sigma NLMS block to system identify a known, 45 tap (only the first 40 taps are non-zero) FIR so I can see where the coefficients end up in the registers. See

Sigma Studio - how to add Readbacks?
Hi there simple question - where do i find the Readback blocks in Sigma Studio? I want to view the value of ADC inputs but I cannot find Readback blocks anywhere in the left hand menu tree? I am using

ADAU1452 eval' board - AUX ADC ReadBack Values
Hi there, I've setup a simple SigmaStudio project to attempt to readback the values returned from the potentiometers on the EVAL-ADAU1452REVBZ, connected to AUX ADC 0 and 1. I want to understand the r

Interface R/W for DAC setup
I am thinking about a small project with the ADAU-1452 and Infineon MA12070P I2S class-D chip. The setup of the amplifier chip is done with I2C, but will it be possible to do these setup changes from

ADAU1701 Low Instruction Level Detection Readback
Hi! I need to read back some signal levels to the microcontroller in my current project via I²C. This works as expected with an "Envelope Peak" block together with a readback cell. These two cell

ADAU1761 - reading interface registers
Hi all, I am using the ADAU1761 to calculate 6 different values, these values have to be read by a microcontroller to be processed further. With the ADAU1701 I could use the interface registers to wri

DSP readback addressing
Hello, is there any way to force sigmastudio to produce contiguous ReadBack addresses in order to read N parameters at once in burst mode ? This is an excerpt of what i get now out of sigmastudio : #d

Wishlist: DSP Parameter Read with input pin for address and output pin for data
It would be a nice feature to have a cell block with an input pin where you can connect a DC block with the address you want to read and an output pin to put out the data from the reading address. The

ADAU1701: Readback of MS Signal Envelope
Hi I am using an ADAU1701 to implement a four channel audio mixer. The first two input channels are routed to the DSP's ADC0 & ADC1, the second two input channels are routed to the DSP's SDATA_IN0 via

ADAU1701 I2C read
Hi My customer is trying to initiate an i2c read from adau1701. Addr0==Addr1=0 => Write addr = 0x68, Read addr = 0x69. Sequence looks like he indeed sends 0x69, however adaqu1701 doesn't send an ack (
