  1. Interrupts for a Newbie

    The code that is avaliable on the link: volatile int state = HIGH; volatile int flag = HIGH; int count = 0; void setup() { Serial.begin(9600); pinMode(GREEN_LED, OUTPUT); digitalWrite(GREEN_LED, state); attachInterrupt(PUSH2, blink, FALLING); // Interrupt is fired whenever button is pressed } void loop() { digitalWrite(GREEN_LED, state); //LED starts ON if(flag) { count++; Serial.println(count); flag = LOW; } } void blink() { state = !state; flag = HIGH; } In this code, I am trying to press the pushbutton P1_3. But it is not showing any status on Serial Monitor. Please need a suggestion from Energia Forum.. Waiting for the response!!!!
