-pinMode()
-=========

-
-Discussion
-----------
-
-pinMode() is usually called within :ref:`arduino-setup` in order to
-configure a pin for a certain usage (although it may be called from
-anywhere).
-
-
-Example
--------
-
- ::
-
-
- int ledPin = 13; // LED connected to digital pin 13
-
- void setup()
- {
- pinMode(ledPin, OUTPUT); // sets the digital pin as output
- }
-
- void loop()
- {
- digitalWrite(ledPin, HIGH); // sets the LED on
- delay(1000); // waits for a second
- digitalWrite(ledPin, LOW); // sets the LED off
- delay(1000); // waits for a second
- }
-

-Arduino Compatibility Note
---------------------------
-
-The libmaple implementation of pinMode() supports OUTPUT and INPUT
-modes with a meaning identical to that of the Arduino function.
-
-INPUT_ANALOG and PWM modes were added because the Maple does not
-distinguish between analog and digital pins the same way the Arduino
-does. Unlike the Arduino, you **must call pinMode**\ () to set up a pin
-for these purposes before a call to, e.g., :ref:`arduino-analogRead`.
-In practice, this should only add a few lines of pinMode() calls to
-your :ref:`arduino-setup` function.
-
-OUTPUT_OPEN_DRAIN, INPUT_PULLUP, INPUT_PULLDOWN, and PWM_OPEN_DRAIN
-modes represent functionality not currently available on Arduino
-boards.
