-pwmWrite()
-==========
-
-Writes a :ref:`PWM wave <pwm>` to a pin.  You can use this to make an
-LED get brighter or dimmer, control a servomotor, etc. After a call to
-pwmWrite(), the pin will output a steady square wave with the given
-duty cycle.  You can change the duty cycle later by calling pwmWrite()
-again with the same pin and a different duty.
-
-The pins which support PWM have ``PWM`` listed underneath their number
-on your board's silkscreen.  These pin numbers are available to your
-program in the :ref:`boardPWMPins <lang-board-values-pwm-pins>`
-board-specific array.  The number of pins which are capable of PWM on
-your board is given by the ``BOARD_NR_PWM_PINS`` constant.  These
-values are documented for each board in the :ref:`Board Hardware
-Documentation <index-boards>` pages.
-
-The Arduino function :ref:`analogWrite() <lang-analogwrite>` is an
-alias for ``pwmWrite()``, but it is badly named, and its use is
-discouraged.

-Example
--------
-
-Sets the output to the LED proportional to the value read from the
-potentiometer::
-
-    int analogPin = 3;    // potentiometer connected to analog pin 3
-
-    void setup() {
-      pinMode(BOARD_LED_PIN, OUTPUT);   // sets the LED pin as output
-
-      pinMode(analogPin, INPUT_ANALOG); // sets the potentiometer pin as
-                                        // analog input
-    }
-
-    void loop() {
-      int val = analogRead(analogPin);        // read the input pin
-
-      pwmWrite(BOARD_LED_PIN, val * 16);  // analogRead values go from 0
-                                          // to 4095, pwmWrite values
-                                          // from 0 to 65535, so scale roughly
-    }
