    Hi Everyone,

    Actually I am writing a code using CodeVision AVR in which the led blinks, whenever the PORTD PIN 4 is high(i have connected a sensor to pin 4,which turns on & outputs 5v).I want to use Interrupt Service Routine in Codevision AVR. In the Code Wizard, it asks for the option for Mode, i.e :LOW LEVEL, Rising Edge,Falling Edge, etc. Which of these should I choose?

    Do you want the interrupt to be generates when the pin goes high?

    If so, choose rising edge.

    This covers it all for you.
