I got EVAL-ADAU1467Z REV B board recently. I have couple of problems:
1- I need circuit schematics of this board.
2- I 'm able to load and run ADAU1467 by MCU via SPI connection. it seems analog outputs of AD1937 is fine with sampling rate 48Khz. I need to increase sampling rate 192KHz. To get correct signal at CODEC outputs I need to change register settings of AD1937 as well. I made connection J6/1(SCL) and J6/3(SDA) to MCU. S2 switch is CODEC BOOT MODE. Unfortunately I Have not able to read register contents of AD1937 nor abble to write AD1937 registers. I realy dont understand what 's missing.
3- Do I have to set some registers on ADAU1467 to communicate between MCU and AD1937 ,it helps if there's sample code for AD1937 I2C communication
