ADC input with unexpected value
I am working with an ADAU1450 and use 4 ADC inputs as volume control. If the volume control is full open I will have 3.25V DC on my ADC_0 input of the DSP. But when I read the value in the software I

fan control with autostart when audio signal is present
Good morning Guys, with ADAU1701 I want to implement heatsink fan control. So I used an ADC input for the two n.o. switch thermostats (I have two analogue thresholds 0V=over-temperature and 1.65V=high

Pin output sequence for power on and shut-down amplifier section
Hi guys. I would like to make a logical sequence to turn on the amplifier section with my 1701s. When I generate the start pulse (I use the encoder button) I need two outputs. The first output goes hi

Serial interface clocking configuration help needed
I am looking for assistance on setting up the clocking of the output serial interface of ADAU1466. I'm using 24.576 MHz master clock fed to both ADAU1466 and 3pcs PCM1795 (connected to DSP via I2S int

Subwoofer DSP problem. Unstable Output with larger input
Hello, I am using sigma studio 4.6 to design a DSP for a subwoofer amplifier. My question mainly surrounds the limiter design. I am running into an issue where the limiter stops working correctly when

SPI Write and Read verification with different SPI offset address.
We need to flash the 'preset data' in specific offset address in the EEPROM flash memory and need to read the 'preset data' from flash memory in run time from the specific flash offset. Is this possib

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 incoming I2S slave clocks routed to I2S slave output
Hello All, I have the ADAU1452 DSP being slave on one of the I2S inputs and on one of the I2S outputs. MCLK is fed by a crystal. Physically the master is connected to the BCLK/LRCLK/SDATA_IN0 and SDAT

ADAU1452 slave/master I2S communication, clock routing
Dear All, I am working on a project where the ADAU1452 needs to receive I2S data from an MCU (MCU is master towards the DSP), from an ADC and a BT module (they are slaves towards the DSP). After recei

How can I change the gain with timer in sigma studio?
Hi, I want to change the gain coefficient("Learning Rate") after 5 seconds. Can it be changed by timer? software ADAU1787 Sigma Studio 4.6 timer Integrated/Special Purpose A/D Converters gain ADAU 178

ADAU1452 TDM IN/OUT as slave input and output with asynchronous clocks
I encounter an audio quality problem on an ADAU1452 DSP configured with a serial subordinate port on the input, and a serial subordinate port on the output. The clocks supplied as inputs and as output

ADAU1452 SPI RAM
HI team. So I bought Adau1452 custom board from China, I am sure this board is common for now. Most of the function is normal. selfboot is also normal. No problem so far. But, I want to do the SPI del

ADAU1452 Detecting the end of a slew-rate limited mute transition
Hi. I have a mute block with a custom slew type (0xAAAA), which gives me a slow fade to mute over about two seconds. Rather than hard-coding the transition time in the MCU, I'd rather get this informa

ADAU1772 - Output Noise level in balanced vs Single-ended
Hi, I am using the ADAU1772 codec to drive low impedance headphones (8 Ohms) for ANC and therefore I need an external amplifier between the codec and my headphones. This additional gain raises the noi

ADAU1401 I2S slave
Hi, I am a non engineer, so I want to make an audio effect using adau1701/1401. but because there is no long delay available, I want to connect it to teensy via I2S connection, but I can not found any

digital input stereo separation in adau 1761
Hello, I am using ADAU 1761 on SigmaStudio 4.6. I am playing a stereo signal from a bluetooth module (BC127) wired to the ADAU. In SigmaStudio, I am therefore using the digital input (input 2/3) going

ADAU1463 TDM16 in slave mode
Hello, We use the ADAU1463 in a system with TDM16 signal 24/32 bits on 48kHz on Serial Port 0 from a FPGA but the dsp is not working correct as slave from this input 0. Every time the systems starts t
