In a bitwise OR operation if there is a 1 in the mask bit, that bit is inverted; if there is a 0, the bit is not inverted and stays the same. Below is a -program to blink digital pin 13 (the LED pin on Maple):: +program to toggle the built-in LED pin (you can also accomplish this +with :ref:`lang-toggleled`):: - // Blink Maple LED pin + // Toggle built-in LED pin - int led_pin = 13; int toggle = 0; // demo for Exclusive OR void setup(){ - pinMode(led_pin, OUTPUT); + pinMode(BOARD_LED_PIN, OUTPUT); } void loop(){ toggle = toggle ^ 1; - digitalWrite(led_pin, toggle); + digitalWrite(BOARD_LED_PIN, toggle); delay(100); } |
