v1.40
Overview
--------
Configures port pins for switches and calls user defined function on switch press. Switch presses can be detected using
IRQ interrupts or by polling. The benefit of using interrupts is that no extra processing is used for polling and the
use of a system timer tick is not a requirement. The downside of using interrupts is that callback functions are called
from within an interrupt so if your ISR is long then it can degrade the real-time response of your system. The benefit
of polling is that functions are called at the application level and debouncing is supported. The downside to polling is
that your system must call the R_SWITCHES_Update() on a regular basis which requires extra processing.
