Hoping someone can help me one what's probably very simple to achieve!
I have an ADAU1701mini dev board. I'm loving it but I'm stuck.
I'm trying to setup a single push button to cycle through four different preset EQ's and also light one of four leds to show which is selected.
I've set up four simple parametric EQ's with an index selectable multiplexer tied to a GPIO. Now I want to turn on one of four leds each on a separate GPIO but I have no idea how to tie the two together.
I'm also a bit stumped on adding a clip led, but I notice some discussions on this already so I'll go read those.
