I am using a SigmaDSP with GPIO (General purpose input/output) or MP (multi-purpose) pins. How do I make use of them in a system design?
Application note AN-951: Using Hardware Controls with SigmaDSP GPIO Pins addresses this issue and contains several examples that can be tested on evaluation hardware.
Note: there is no difference in meaning between "GPIO" and "MP."
Where can I download a guide for the Sigma100 BPIO daughter bord?

Documentation for the GPIO board can be found in the datasheet for the EVAL-ADAU1701EBZ. You can find this document on the ADAU1701 product page, under the Evaluation Boards/Tools link.
Is there an up to date schematic for rev B? I did find the old version in the ADAU17xx eval docs as stated above...
I plan to revise "AN-951: Using Hardware Controls with SigmaDSP GPIO Pins" to include the Rev B schematic. For now, I've attached it to this thread.
