hi steve.. thanks for the update.... i forgot to update the post here but i managed to track down a copy of PICBasic Pro from a friend of mine and got him to compile the program for me. lol solves the problem and having to change the codes. Thanks anyways... oh any idea where i could find a virtual breadboard? not the one from http://www.muvium.com/ (previously virtualbreadboard.com). I came across a few versions written in java but does not have the 16F84 chip. anything that can help?
