Digital Code Lock With 3310 LCD

Hi guys!

I found this site searching for starting-informations in my AVR-Programming-life. This is the perfect matching source-code for me.

Majoka, I downloaded your code tried to understand it in order to modify for my propper project.... I think i understand almost every... well most... ok: particular

I recognized that you use Klein and so I searched the C51-Program (V 9.01) and learned the basics in order to understand the important things.

BUT:
My first BIG Problem is the compiling.....
My generated hex-Files dont work simulating in Prometeus. Even when I re-compile your main.c File it doesent work (btw: the new hex-file is only 3kn. The original 9!!)

Do you (or anyone else) have an idea where my initial fault could be?!

Best Regards
Marcus

I Forgot: Here are are some (!) lines of the output-window

hi wawa, i also downloaded that code from majoka and it has no error. try to
remove STARTUP.A51... from the group and compile it. i also got many errors when that startup file is included.. hehe i dont know about that file but i just remove that...

I retried!

When starting up, the system asks me if I want to include this file. This time I said "no", but the result is the same

Build target 'Target 1'
compiling main.c...
MAIN.C(22): warning C275: expression with possibly no effect
MAIN.C(45): warning C275: expression with possibly no effect
MAIN.C(56): warning C275: expression with possibly no effect

blablabla....


Welll maybe its because of V 9.01 instead of 9,1 ??!!
