Thread: Last few errors in making an USB protocol

Seriously, a whole project code dump with no indication of where the problems are that you see? What functions are you calling? Where? What header file are they in? Have you included that header into your main file? Just throwing a ZIP of your project at us isn't helping, it's hindering.

You honestly expect someone to download, unzip, compile, test and debug 700k of C source code (not even for a standard device we're likely to have lying around), for you, just to locate a missing header include? Hell, I had to virus scan the ZIP just to download it to see its contents, let alone just let it and its complete Makefile and 700k of source code (that I'm NOT going to audit) just run rampant over my user account when I compile it.

Publish the exact error you are getting and honestly, if they are simple errors that TELL you what's wrong, I will shout at you.

Lol looks like someone fell down the wrong side of the bed. Just tried to help by posting the complete project.
The errors are:
main.o: In function `main':
c:\documents and settings\*****\desktop\new folder (3)/main.c:16: undefined reference to `ccp_write_io'
c:\documents and settings\*****\desktop\new folder (3)/main.c:19: undefined reference to `sysclk_init_opt'
c:\documents and settings\*****\desktop\new folder (3)/main.c:23: undefined reference to `udc_start'
main.o: In function `udc_attach':
c:\documents and settings\*****\desktop\new folder (3)/udc.h:25: undefined reference to `udd_attach'
make.exe: *** [main.elf] Error 1

Include files are everywhere. I'm still trying to figure C out.

Code:

#include "compiler.h"
#include "preprocessor.h"
#include "sysclk.h"
#include "conf_usb.h"
#include "udd.h"
#include "udc.h"
#include "udi_dfu_atmel.h"
#include "twim.c"








int main(void) 
{
    // Map interrupt vectors table in bootloader section
    ccp_write_io((uint8_t*)&PMIC.CTRL, PMIC_IVSEL_bm | PMIC_LOLVLEN_bm
            | PMIC_MEDLVLEN_bm | PMIC_HILVLEN_bm);


    sysclk_init();
    cpu_irq_enable();


    // Start USB stack to authorize VBus monitoring
    udc_start();


    udc_attach();
    while (true) {
    }
}

I'm a quick study, I managed to understand basic full within 2 days

And now someone who can actually help me out instead of posting lame ass comments

Read this post once more. It answers the problem you are having.

Missed that post, tnx for the reminder. Will check it the first thing in the morning

I've added the ccp.h include file but still after including I receive the same errors.
The other 3 errors from sysclk and udc were already included so I don't understand why its going wrong.

I've tried to compile in WinAVR and AVRstudio 5 and 6, even with different compiler settings but every time I get those errors again.

YOU NEED to link to the file/library that supplies the missing functions!!

Including a header does NOT link to any file when using GCC style compilers!!

Look up how to compile and link multiple files; And/Or, how to link to libraries.

tnx all, fixed it.

@ stahta01 tnx for pointing out that I had to include the .c files in the makefile this helped a lot.

Threw the whole project in the trashcan and opened a working example project in AVR Studio 6 for xmega.
Only thing was that is was for a different xmega then I use but fixed that already.
Finally I can make the actual software instead of debugging a faulty one.
