What is GPIO?
General-purpose input/output (GPIO) is a generic pin on an integrated
•
circuit whose behavior, including whether it is an input or output pin,
can be controlled by the user at run time.
GPIO capabilities may include:
•
GPIO pins can be configured to be input or output
•
GPIO pins can be enabled/disabled
•
Input values are readable (typically high=1, low=0)
•
Output values are writable/readable
•
Input values can often be used as IRQs (typically for wakeup events)
