* adc.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.
