Version

-------
|

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.
|
||||
|
||||
Features
|
||||
--------
|
||||
* Call one function to setup switches.
|
||||
* Define function to call when switch is pressed.
|
||||
* Can be configured to be interrupt or poll driven.
|
||||
|
