how to wire an external DAC and to make it output some sound using an app made with sigma studio 4.7
hello, I have an eval_adau1467Z board, I am able to implement various use cases in it, like using toslink input, doing 2 way crossover and outputing low pass audio to channels 0&1 and high pass to cha

Issue with external MCLK
Dear Community, I am experiencing a weird issue with the clock settings setting up an ADAU1467. When I apply an external 24.576Mhz clock to the MCLK Pin the bitclock I see on the serial outputs is too

ADAT Lightpipe with Serial Port and external Logic
Heiio community, I want to send 8 audio channels via ADAT from a sigma DSP to PC. After reading this discussion https://ez.analog.com/dsp/sharc-processors/f/q-a/61533/sport-and-adat I came up with an

Multiple External Potentiometers
I understand this DSP only has Four DACs, so I can only use 4 potentiometers in my SigmaStudio project. I am trying to use total of 7 external potentiometers to manipulate the audio coming in. Any sug

External button to select internal crossovers.
Hello everyone, I’m new to SigmaStudio and I’m working on programming the ADAU1401 to use an external button to select internal crossovers. I have successfully set up the blocks for external volume co

Use both internal and external TDM DACs
I know I can't use both TDM and l2s devices at the same time. But what about internal DAC's and ACD's, and an AD1938 in TDM mode? If so, can I mix the 4 internal DACs and up to 4 of the 1938 DACs? Aud

ADAU1452 spi extern delay module do not work
I use SPI SRAM (23LC1024) connected to the master spi interface of 1452, and test the sigma studio module. But I found that it do not work well. the audio playing back is not right. the sigma studio p

ADAU1452 multiple instances of External Delay block
Hi to all, I need to implement a 4IN - 8OUT processor on ADAU1452 and I need to manage 4 long delay cells, one for each input channel, with different values on each. The RAM inside ADAU1452 is not eno

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

Issue with ExtSPIDelay on ADAU1452
Hello, We are using the development board for the ADAU1452 because we need to implement a big delay (we expect to be able to delay our sound up to 35 seconds). I am trying to use the functionality but

External oscillator with ADAU1701 and multiple I2C codecs
Hey all, I'm new to the SigmaDSP platform and am currently working on several of my own designs using the ADAU1701 and ADAU1452. I also intend to use an external oscillator with at least the 1701 for

Read filter from I2C EEPROM
Hi! I am using the ADAU1466 in a current project. It is selfbooting from an SPI EEPROM but uses I2C for control. I was wondering if there is any way that the DSP could pull filter settings for one spe

External SPI Delay on ADAU1466
I am working on a project that requires a significant amount of delay. Altough all of the examples I've found concerning external SPI delay refer to the ADAU1452, I find that SigmaStudio shows the opt

Different behaviour on ADAU1450 and ADAU1452 with external SPI delay
Hallo guys, we're developing an application based upon the ADAU1450 including the external SPI memory for additional delay (23LC1024-I). Although the same project works well on the ADAU1452, it doesn'
