I am currently using an ADC configured GPIO on an ADAU1446 to control a crossfeed block with a potentiometer. I would like to change this to a two-button up/down control with maybe 10 discrete steps. SigmaStudio has a block for a pushbutton volume control, but not a crossfeed version. I am assuming that I can emulate the ADC using the up/down GPIO control blocks with a look-up table, but I have not had any luck so far. I would appreciate it if any of the SigmaStudio gurus out there could give me a few hints.
