Hi,
I am new to use AVR - GCC. On windows-XP. I need your help. Currently i am using WinAVR-programmers notepad, AVR studio to work using ATmega168 microcontroller. I am getting some problem while using these tools (i am not getting the .cof file). Basically i am following the procedure as described below.
1] On Winavr programmers Note pad I am creating the New project(ex: project1), Then i am creating new file by FILE->NEW->C/C++
(ex: project1.c)
2] I am editing C-Program on this file, then add this file to the project+save.
3] In C:\WinAVR\sample there it contains a Make file. I am simply adding this make file to the project, On double clicking this make file it opens here i am specifying 3 options
A] MCU = atmega168![]()
B] TARGET = Project name without Extension(project1)
C] OPT = 0
for simple one .c file
4] File->save
5] Tools->[Winavr] Makeall to compile the code.
6] Here in output window i am getting

7] Then i am opening the TOOLS->OPTIONS in options window iam sellecting the TOOLS->ADD
here iam adding the properties: NAME :[Winavr]MakeExtcoff
Command : make.exe
Folder :%d
Parameters :extcoff
Consol i/o: Capture o/p
Use an Individual o/p window
Clear the o/p before the running
Then clik OK+OK
8] To run the ExtCoff utility choose the "[WINAVR] Make ExtCoff" from the "Tools" menu iam grtting the o/p

finally i am getting( .c, .pnproj, .pnps, .lst, .o) files
Here if i got the .cof file i will simulate the code by taking this .cof file in to AVRstudio This is my idea
-> Tell me is this procedure is right/wrong
-> Give me your suggestions to get the .hex file
* If i am using directly AVRstudio I am getting the All the files
Tell me the correct procedure
Thankyou
