this is probably way below any of you guys but i am a college student and i am lost when it comes to this assembly stuf. we haven assingment where we have control a led bar with 8 switches. when each switch is turned on the corresponding light is turned on but when the 3rd switch is on . all lights turn off. i think you have ot use interrupts to do this. but i'm not sure how to make the program realize that a switch has changed it's state and then from there find out which switch. if you can help at all please let me know
