ADAU1467 selfboot and AD1937 i2c
I'm using the ADAU1467 driving a AD1937. I'm able to configure the codec and all is working fine only if I don't select the selfboot mode. In order to use the selfboot mode, I load the eeprom (via dsp

How to change sample rate on EVAL-ADAU1467 ?
Dear all, I am using EVAL-ADAU1467Z Rev. B. As far as I understood, sample rate on EVAL-ADAU1467 is fixed to either 44.1kHz or 48kHz, when switch S2 is set to standalone mode. According to the user's

EVAL-ADAU1467Z - i2s on SDATA_IN2
Hi, I'm planning on building a prototype using the EVAL-ADAU1467Z evaluation board. The design uses 8 MEMS i2s microphones. 6 of these will be connected to SDATA_IN0, SDATA_IN1 and SDATA_IN3 on left-r

Wrong include generated for ADAU1372 on Sigmastudio 3.14.1 beta
I wanted to point out that the C code generated by SigmaStudio 3.14.1 beta contains errors. Specifically, the code to load the ADAU1372 is wrong because it declare 0 as the size of PLL_CTRL5 register.

AD1939 in selfboot system
Hi! I have a SW/HW question about programming the AD1939 CODEC in a Selfboot ADAU1446 DSP-System. My board works well with the ADAU1446 in I2C Mode, with selfboot from EEPROM (I2C) and with the AD1939

AD1937 - Can I set ABCLK per frame to over 64cycles in I2S stereo mode?
Hello, AD engineers. I am using AD1937 for recording and I am just checking ad1937 for what kind of BCLK and LRCLK I can use when I record. I have several questions about BCLK frequency for ADC operat
