noInterrupts()
Class
GPIO
Description
Prevents interrupts from happpening
You can use noInterrupts() and interrupts()
in tandem to make sure no interrupts are occuring while your sketch is doing a
particular task.
br/>
While a method associated with a pin's interrupt is being executed, interrupts
from the same pin are automatically prevented from occurring. Interrupts from
other pins can still happen, however. If you also want to prevent those, put
noInterrupts() at the beginning of your callback function and interrupts() at its end.
Examples
import processing.io.*; color bgcolor = 0; void setup() { GPIO.pinMode(4, GPIO.INPUT); GPIO.pinMode(5, GPIO.INPUT); GPIO.attachInterrupt(4, this, "pinEvent", GPIO.RISING); GPIO.attachInterrupt(5, this, "pinEvent", GPIO.RISING); } void draw() { background(bgcolor); } void pinEvent(int pin) { GPIO.noInterrupts(); // no other interrupt will disturb us println("Received interrupt on pin" + pin); if (bgcolor == 0) { bgcolor = color(255); } else { bgcolor = color(0); } GPIO.interrupts(); }
Syntax
.noInterrupts()
Return
void
