hi, i'm newbie here and avr.., i've some problem when i try to compile my source code..
Crying or Very sad

.., there are like

Quote:

undefined reference to"Timer0_RegisterCallbackFunction",
undefined reference to"LCD_UpdateRequired", etc..

I attach the source code, i take this from bf_gcc with some editing cause i just need light meter code

thanks..

When you see "undefined reference" it's an error from the linker that says "all the .c and .S files in the project have been built to create .o files, I've then joined them all together but in there there are some calls to XXXXXXX which none of the .c or .S files provided".

In other words you forgot to add the .c files that provide Timer0_RegisterCallbackFunction() and LCD_UpdateRequired() to the list of .c files to be compiled.

To expand a bit on Clawson's post, if you are using AVR studio, you need to add those .c files to the list of project files. In Studio4, that is done in the list of project files and there may be a way from the File menu to do that, also (Studio is not on the machine I am using right now). I don't remember the precise mechanism but it may use a right mouse-click on the project name, or something like that. In Studio5, I have no clue, but its probably something similar.

Cheers,
Jim

Indeed it is then use "Add Existing Source File(s)..." and pick them in the resultant file selector. Life is simpler if they happen to be in the same directory as the other project files.

It appears to be here:

http://gandalf.arubi.uni-kl.de/avr_proj ... tml#bf_gcc

I take it that means the GCC conversion of the Atmel Butterfly code that Martin Thomas did.

thanks

But did you add those .c files to the project?

"some error" - very descriptive. Any chance of saying what "some error" actually is and I mean the EXACT wording.

OK now change:

Code:

#include <main.h>

#include <ADC.h>

#include <BCD.h>

#include <LCD_functions.h>

#include <timer0.h>

to be:

Code:

#include "main.h"

#include "ADC.h"

#include "BCD.h"

#include "LCD_functions.h"

#include "timer0.h"

and make sure the names on disk are exactly that case.

undefined reference to `main'

There is a generic explanation above on how to interpret 'undefined reference to something". Did you read it? Did you understand it?

In essence, when building the application a definition of the main function can not be found.

Have you supplied such a definition?
Have you added the file with that definition to the project?

Absolute base-line: Do you know that this function is needed in any and all C programs, and do you understand it's function?

It seems to me that you've chopped up the original code provided by Martin Thomas without really understanding the basic principles for using AVRStudio to compile and link a program.

The Butterfly code has some very complex cross connections in the various modules. The relationship between the LCD and other modules is particularly fraught.

I'd strongly recommend that you read Dean's Butterfly LCD Tutorial: http://www.avrfreaks.net/index.php?name ... mp;t=36234 and get that working first. Then figure out how to use the ADC as a later issue.

Are you saying that there often is no such thing as immediate reward w/o any lengthy learning process involved?!?

I'm shocked and flabbergasted.. Shocked

Can: Maybe. Want to? No.

1. You are jumping from thing to thing here. You've now opened up the subject of smileymicros tutorial w/o the original question/problem being resolved. At our end this looks like you're abandoning the original problem, and we've spent time helping you in vain. Even if you've not abandoned the original problem, this discussion is now a "moving target". We loathe moving targets.

2. You are not supplying answers to questions asked. I was trying to determine your level of knowledge on the C language by asking about the main() function. You've not bothered to answer. So now we (still) don't know at what level we should supply help - obviously risking that help we give is not the one needed and out time wasted once again.

3. The formulation "there's nothing apears on the hyper terminal...?? can u help?" clearly indicates that you either can to do basic fault seeking, or could but haven't, or have but won't tell us. So once again, we need to start at some point, but you don't give us a chance determining where that is. Again any advice we give has a high likelyhood to be wasted.

No. I won't help.

Think about this: The quality of the answers you get is correlated with the quality of the question you ask. (Ask bad questions and people will walk away. Ask ood questions (and make good answers to counter/followup-quations!) and people will stay and help you.)

Me? I'm out of here.
