Alhamdulillah,
I manage to work with SPI control. But...
I wonder why the signal at the MISO line is not stable. Unacceptable Inconsistent data output from ADAU1701 and sometimes, when there is a data that comes out from ADAU1701, attenuation is occured on that data's signal.
The attenuation of the signal was really affect the data's value from ADAU1701. Figure below shows the Unacceptable Inconsistent data. (I should get consistent data of 1F,D9,3C)
On the other hand, MOSI, SCK, and CLATCH signals were doing just fine.
I've cut the pull-up resistor for MISO line from figure above (20140716 - SPI interface). I also try to use Bi-directional level converter. Both method are not solve this problem.
Any suggestion to fix this problem?
(these messes is not over yet. the problem is not solved yet: currently i am using Bi-directional level converter except LC04A of direct line of MISO signal)
Thanks!
