hey i made a code for graphic lcd for connect that with lpc2148. nd there is not an error in that code. nd code debug in gpio port 1. bt i cant got the connection of pins. the problem is on which pin of glcd i have to coonect the pin of lpc2148..
my code is atteched below..

When you "make" code for a processor + GLCD, you write the code for the specific hardware bundle - which obviously includes the actual connections between processor and GLCD.
If you have code but don't know what processor pins to connect to what GLCD pins, then you haven't "made" that code. You have found it somewhere.
The bad thing about "finding" is that you may not understand the code. So time to spend some serious time reading your located code then and figure out exactly what it is doing. As a hint - you need to also retrieve the datasheets/user manuals for processor and GLCD.
