/*
 * userio.c: reacting when you fiddle with buttons, switches, and knobs
 *
 * mode switch: modes are changed only when the button is not being
 * pushed, as button being pushed negates the mode switch response.
 * for the mode to change, the mode switch must be in the new position
 * without wavering for at least 3 rounds. this will prevent the
 * mode from changing by someone fucking around with the button or
 * when the button is used normally.
 * 
 * button: is connected to mode switch ADC. if below threshold, then
 * we can be certain button is pushed. we still wait a debounce
 * round to ensure button is pushed. our code can fire events on
 * either button being held or button being released. the actual
 * push event does not do anything with this code.
 * 
 * settings knobs: these are used by the settings module which works
 * with the other modules and the button for setting user settings.
 * the values are scaled from the ADC value, with bounds being set
 * on the low and high ends and further scaled for usability.
 * please read the manual if you want to know what settings do.
