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

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

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

Problems with EVAL-ADAU1452RevBZ in TDM mode
Hi, I'm trying to develop a multi-canal system with ADAU1452 in TDM16 mode that communicates to ADAU1966A in Standalone Mode (TDM16, Slave serial audio interface and 256 × Fs ). I control the DS

Master Control Port Runtime Sequential Write - Dynamic value
I am using an ADAU1462 and am having a hard time writing a value, decided on runtime, to I2C. Is it only possible to write hard-coded values, defined in the sequence file, to I2C? I have been trying a

eval-adau1467 with external master clock - how?
I am trying to evaluate an external synth as master clock (si5340) for our dsp product based on adau1467. So, my idea was to connect the output from the synth to the middle pin on J3 on the adau-1467

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

ADAU1701 TDM In - I2S out
Hello, in my current project I'm using an ADAU1701. On my system MCU I implemented an USB-to-TDM-Interface which delivers 8 channels with 24 bits at 48 kHz via TDM8. The Masterclock is 24.576 MHz, the

ADAU1467 Dual Master Control Port
I'm starting a new thread based on this post by DaveThib: "If you absolutely MUST use a SPI EEPROM for fast booting and be able to control some I2C parts then you will have to move over to the Sigma35

Clock Routing
Hi ! I recently started designing an ADAU1466 based DSP board. After first considering the standard AD1938 as codec, i quickly diverted to separate ADC and DACs (Cirrus Logic in this case). Having res

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

PLL Enable/Disable not working when selfbooted
adau1452 i2c selfboot Hello Community, we are having problems when trying to disable and re-enable PLL after ADAU1452 has self booted through I2C eeprom. Here is a brief description of my project: I b

No output from ADAU1452 Master Control Port IO
I'm using a Master Control Port IO Ext. Trigger cell to write to a SPI peripheral. The schematic generates SPI output Mode 3 but no output (no SCLK) if I switch to Mode 0. I've attached a simple schem

Compile error ADAU1452 Master control port SPI
I'm trying to use the Master Control Port IO block in SigmaStudio v3.15 build 3. The release info for 3.15.2 beta says it's supported: "Master Control Port Runtime Sequential Write and Master Control

Master Control Port Runtime Sequential Write (ADAU145x)
I'm in the process of making schematics/PCB for my system, which includes the ADAU1452 and an ADC with built in PGAs that can be programmed via I2C. It would be very convenient to use the ADAU1452 Mas

USBi controlled outside Sigma Studio
Can I control the USBi (ADUSB2Z) board using my third party program (windows c# application), and NOT SigmaStudio... This is intended to work after DSP is programmed by Sigma studio. I, then, close th

ADAU1452 Master Control Port
Hi there. I want to boot a codec (AD1939) over the master SPI port of the ADAU1452. When trying to drag, drop and configure the 'Master Control Port I/O' block in Sigma Studio (3.10.4 or 3.11 beta) I

How to route TDM audio through multiple ADAU1701s?
Hello all, We're developing an audio mixer around a ring of ADAU1701s where each receives a TDM steam from its neighbor, adds in two analog inputs and sends the mix through to the next -1701. The bloc

AD1954 master/slave setting
Hi, I want to use the ADC->AD1954 to implement my project.I set the serial interface mode of the ADC to be master mode and I^2S.So I need to set the serial infterface mode of the AD1954 to be slave mo

Switching I2S Slave mode to Master mode on the fly
our development involves an Arm processor using SigmaDSP to output Audio to Headphones/Speakers. Following is a simplified sequence of operations from ARM's point of view: starts up (I2S is not yet se

multiple ADAU144x system
I'm having trouble using a SigmaDSP as an I2S slave. In all the examples I see SigmaDSP as a master but in a multi-DSP system one will be a master which drives another SigmaDSP slave and a slave codec

ADAU1702 Master Clock to drive external ADC and DAC
Hi, I'm designing a system with a ADAU1702 and better performance ADCs and DACs. Should I take the master clock from pin31 "OSCO" pass it thru a buffer/ inverter? and maybe increase a bit the 100 ohms

ADAU1446 Serial INPUT/OUTPUT ports run mode
Hi, May the INPUT/OUTPUT ports work in master mode at the same time? If all work in master mode, the CLOCKs source is the same "MASTER CLOCKs"? or the input/output master source is not same(synchronou

Can I use the ADAU144x as a clock master for an asynchronous clock domain?
Can I use the ADAU144x as a clock master for an asynchronous clock domain? For example, I have an input data stream that will be a slave to an asynchronous clock domain. I will route it to the ASRCs,
