Hi Everyone,


Am using ADAU1452, I need to control volume,frequency, Pitch using push buttons. I didn't find any free gipo's in my schematics. How can we control 7 push buttons using one GPIO.


I have seen related thing i.e, controlling using resistor ladder network. Is it possible to control like that via Sigmastudio.

Please do the needful.
