pinSetFast()

Write a HIGH value to a digital pin.

// SYNTAX
pinSetFast(pin);

pinSetFast() takes one argument, pin: the number of the pin whose value you wish to set HIGH.

pinSetFast() does not return anything.

// EXAMPLE USAGE
int LED = D7;              // LED connected to D7

void setup()
{
  pinMode(LED, OUTPUT);    // sets pin as output
}

void loop()
{
  pinSetFast(LED);           // set the LED on
  delay(500);
  pinResetFast(LED);       // set the LED off
  delay(500);
}
