Dear all,
I'm trying to make an Door Security System Using RFID with LCD using pic16f877A. I was trying to defined my ID tag number on the code in MicroC program but it is not working on my simulation , I want to save some ID tags number like ( x=12345// john's card , y=54321// Sara's card) as a variable and when RFID reader read them it should show tag and the cards number which meaning the the entering is approved and if else it will say "it not correct" . Now i rote the code to do that but im not taking what i want im lookng forward of your helping
Here is my code
