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

[ADAU1452] Regulations regarding the waveform rounding for the rising and falling edges of the reset signal
Hi, We have a question from Customer. Regarding the reset signal of the ADAU1452, are there any regulations regarding the waveform rounding for the rising/falling edges? We checked the data sheet, but

ADAU145x generating a reset signal for max hold when reading for example IPAT registers
Hello all, Does anyone know if it is possible to generate a reset signal for a "max and hold" block when reading from, for example, an IPAT register? I have five digital signals on MP inputs, which ca

resizing application window is difficult to impossible
Windows 10 22H2, 4k monitor. SS+ window can only be resized by grabbing in the corners, and it's very touchy as to where you have to position the cursor to get the grab handle (double arrow) to show.

How to use EEPROM block in SS+ for an I2C part?
I have a board with an ADAU1452 and an EEPROM that are controlled via I2C from a small micro. I would like to be able to load/read the EEPROM contents from SS+, which if you go to the settings looks p

Do the Compressor Ratio and Knee can be calculated or have formula to use?
Hello, I have read DaveThib document: 3022 Standard Compressor Meter variables and calculations for the Sigma300 and 350 processors. This topic really helps me a lot to understand the compressor and h

Is it possible to implement preset settings on a stand-alone ADAU1452?
Hello All, For a new design I would like to use only the ADAU145x DSP without a controlling microchip. Customers will be able to write their own DSP application in SigmaStudio and upload it into an fl

Compressor input level appears to be displayed/calculated incorrectly
During some recent work, I have been using one of the compressor blocks (Dynamic Processors/Peak/Standard/Full Range/Standard Peak). I noticed the "IN" Level displayed on the level indicators appears

ADAU1787 PLL Input Prescaler
When I change the input divider to the PLL (CLK_CTRL2 bits 2:0) between the values of 0 and 1 it doesn't seem to change the clock rate?For verifying clock rates I am monitoring the MCLKO pin. If I am

ADAU1463/67 State of I2S Bus in RESET
Hey everyone, quick question about the ADAU1463/67 State of I2S-Bus-Pins in RESET Mode. I suspect the ADAU1463 is behaving similar to the ADAU1451 on the I2S-Pins, therefore the answer ( RE: DSP - ADA

AN ADDRESS ERROR OTHER THAN 0X68
Hello, there. I can't run ADAU1701 at a different address than 0x68. The hardware is the same. I'm just changing the link to the address pin. It doesn't work. The Sigma studio device is not connected

EVAL-ADAU1467 termination resistors for SDATA_IN# lines?
Hi there, I am looking at the EVAL-ADAU1467Z-schematic for some pointers on how to start our own design base around the ADAU1467 DSP and I can't understand why you place termination resistors (R12 and

Setting up an ADC with an ADAU1463 over I2C
Hi, I'm trying to Settup an ADC through I2C. The ADAU1463 operates at Selfboot Mode, so I have to settup the ADC with the DSP. I've tried to send I2C writes with the "Master Control Port IO" block, bu
