How to write volume value from spi-connected Arduino to safeload?
Hi. My problem is that I shut down the power using push volume on adau1466 When turned on, the volume is initialized (interface read, write does not work) So, by connecting Arduino Nano with SPI, I wa

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

ADAU1467 Eeprom Interface Write problem
I'm using an ADAU1467 with self-boot eeprom. Writing to the eeprom via the DSP works no problem, using the same settings as the EVAL board. However, I'm using a Rotary Encoder for volume, and I want i

ADAU1452 PEQ safeload
I'm developing a board composed of MCU and ADAU1452. SigmaStudio v3.13 is used to create block diagrams. MCU can make ADAU1452 work by I2C,also can Control the volume. SO I think I2C operation has no
