I had this working swell with a pushbutton on a counter. Now I want a turn a pot and select different filters, sort of like "presets". Clearly I am doing something wrong. What is it? The GPIOs are to turn on LEDs to indicate which index is selected. This project is for the 1701minibz eval board. Table values are 0 0.25 0.75 1. The aux adc is 3.
