Hello! It is impossible to master the array of information in the technical documentation. I hope for help. There are ADAU1452 + AD1938 boards.
I need to build a chain:
AD1938 - ADC input 2 channels, I2S output 2 channels.
ADAU1452 - I2S input 2 channels, I2S output 8 channels.
AD1938 - I2S input 8 channels, DAC output 8 channels.
Is it possible to use AD1938 both at the input and output of ADAU1452? If yes, please help with the setup.
Important! It is necessary to leave the maximum GPIO free in ADAU1452. And for this, if I understand correctly, you need to use the TDM mode. And organize 8 channels on one DSP output. This is not a problem. But will the AD1938 be able to turn 8 TDM channels into 8 line outputs? Sorry for my English. Thanks!
