kvbhat,

I downloaded your files and compiled them with Keil C51. I included the default startup.a51 file, and have NO errors or warnings when I compile your MAIN.C file.

Since you did not include the source modules for the other files, I cannot build the entire thing.

Can you please show the warnings you are getting?

Thanks,

-Dave

From your question, I assume this isn't your software, but something you borrowed from someone else. Is this the case? If not, I apologize, but the question seems odd. If you could screen print your screen after you get the warnings, you could attach the picture to this forum so I could better understand what problems you are having. This would be very helpful in fully understanding your problem.

To answer your question, your RAR file included these files:

Obviously, I don't need to see the included library files from Keil, because I assume they are correct.

In case you don't know what I am talking about, that would be anything having to do with the functions listed in stdio.h and 89c51.h - These header files are for a library that comes with Keil and a register definition file, that also comes with Keil, repectively.

However, you have header files called delay.h, lcd4,h, adc.h, serial.h, fbus.h, and keymatrix.h. These must have source modules that have source code for the function prototypes in the headers.

In order to compile the entire project, I would need these modules.

I hope this helps you,

-Dave

*** WARNING L2: REFERENCE MADE TO UNRESOLVED EXTERNAL
SYMBOL: _DELAYI
MODULE: Main.obj (MAIN)
ADDRESS: 1FF6H

this and many more similar to this are the warnings.

You are right sir i havent done the entire code myself ,took help of my friends and some of them are currently out of town..

Even if the warning persist and i burn the code in microcontroller will the code work??

Thnx for the reply

No, it will not work without resolving the warnings. These warnings indicate that there are external functions that the linker cannot find. The one you specifically show here is the Delay function. No doubt, it is in one of the missing modules I was referring to.

You must include these modules in your project, and then compile and link them together for this software to work...

Sorry,

Dave
