Shift incoming I2S data left 7 bits
For reasons that are too long to explain here, the I2S data is arriving (logically) shifted right 7 bits. This is fine because it's really just 16 bits of valid data. Before I can use the data I need

ADAU1787 i2s input to DAC Output with filters
Hello, I want to pass the incoming i2s signal (from a bluetooth to i2s device) to EQ Filter and then as output to the DAC. I used this as an example, but removed the FDEC: ADAU1787 two-way bluetooth s

EVAL-ADAU1452 - distortion on i2s inputs
Hi there, I have an external i2s source which I connected to my logic analyser to confirm a solid digital signal: It shows a 3MHz SCLK, 48kHz LRCLK and the i2s analyser gets good 24-bit data values. I

ADAU1701 -- I2S source without MCLK
As I understand from the datasheet (for the ADA1701 mini evaluation board), when reading audio from an I²S source, I need to connect the MCLK (approx. 12MHz) to the ADAU1701 input. Is there a way arou

I2S input on ADAU1702
ADAU1702 I2S Slave configuration When the ADAU1702 is used as an I2S slave, the stream is not read in as should. The audio data is however not clearly received. This is a simplified design of our syst
