newbie...

hi Gurus,
You all must be wond3(e)ring why I saluted with "Guru"s
As stated in subject line I am new to Embedded system, and
electronics. and for me, all of you are geneous than me. from each of
your hint, i am going to learn.
Yup, for your reference, I am B.E. IT from reputed COE in MS India. I
know C, C++ and Java with JSP and JScript.
My dream to work as system programmer, doesn't matter if its other
company of mine own. (Why am i working as maintainence programmer???)
But I really work in Embedded system at least as hobbyist.

Now I am starting with PIC 16F877A. I got a development board
(localized, not standard) and a ICSP(whats this?) programmer. I am
using proteus 7.0 and MPLAB.

on my board, there are 8 LEDs which are connected to PORTA and I am
desparatedlyyy wanted to blink one of those LED(so that i can proceed
to other things with confidence). but but but.... those are as good as
dead. I wrote a program for it. whn i simulate, it works fine. but
after writing on MCU it is showing nothing but dead LEDs.

Now I am stuck. I beg your request to help me out. Plz Plzzzzzzzzz
help me. I am stuck.....
