/*
DEBOUNCE_TICKS_DOWN and DEBOUNCE_TICKS_UP are in terms of fast_cb ticks after a button is pressed.
The logic is that pressed of a button are ignored until the cb_fast_tick function runs this variable amount of times.
Without modifying the code, the cb_fast_tick frequency is 128Hz, or 7.8125ms.
It is not suggested to set this value to one for debouncing, as the callback occurs asynchronously of the button's press,
meaning that if a button was pressed and 7ms passed since th elast time cb_fast_tick was called, then there will be only 812.5us
of debounce time.
