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.
|
