Hello,

I have been playing around with the ADAU1467 eval board (EVAL-ADAU1467 Rev. B) and am not seeing an output on OUT2, but I am seeing an output on OUT1 channels. I imagine this is probably an incorrect serial setting in the hardware tabs, but I can't seem to figure out what might be causing it. Any help setting this up would be greatly appreciated!

Thanks!

Just checking back if anyone knows how to get the other analog outputs working. Only OUT1 is working now. Maybe something wrong with the board?

Is there a better way to get technical support for DSPs? Normal ADI technical support is very good with other ICs, but this post has been on EngineerZone for almost a week and no answers. What should I do?

John,

I'm very sorry for the delay. Things have gotten a little backed up. I suspect your problem is in the configuration of the SDATAIOx pins. I've attached a skeletal project that shows the correct configuration for all I/O. Please let me know if you have further problems.

Hi Ken,

This was very helpful. I made the following changes to my serial setup and it is now working. Thank you so much!
