4

Has anyone had success using xcode 4 as an IDE for AVR microcontrollers? Is it possible to have the same amount of integration as the plugin for eclipse?

Yes. I use Xcode 4 as IDE when writing AVR code.

But it only works as a "wrapper" for the avc-gcc command line tools. I have three Xcode targets in the project: build ("make all": compile only), fuse ("make fuse": program fuses) and flash ("make flash": compile and download to AVR). Just select the appropriate target and hit Cmd-B to build.

There is not much integration. I still have to edit the Makefile to set clock frequency, programmer and device model and fuse values. And if I add more .c files I also have to add the corresponding .o file to the Makefile. But at least I can do it from within Xcode.

I have created a minimal project template that will allow you to create a new AVR project in Xcode. Get the file here http://dl.dropbox.com/u/1194636/AVR_Xcode4_template.zip. Extract the archive and put the Atmel AVR® folder into ~/Library/Developer/Xcode/Templates (you might need to create the Templates folder).

Template from second answer (http://dl.dropbox.com/u/1194636/AVR_Xcode4_template.zip) works fine but with some tweaks.. You have to put these in file "makefile" in the template to be able to include multiple files in the project:

OBJECTS    = main.o $(OBJ)
SRC =  mynewfile.c
OBJDIR = .
OBJ = $(SRC:%.c=$(OBJDIR)/%.o)
LST = $(SRC:%.c=$(OBJDIR)/%.lst)

in SRC section you need to enter all files that are built in the project (for example mynewfile.c).

One more enhancement is to clear all the obj files from the project, after the linking ... Find the section main.hex in makefile and change rm -f line with following

    rm -f main.hex $(OBJ) $(LST) main.o

Other then that, everything stays the same. What i couldnt find out is how i can enable code complete for this template. If anyone knows i would appreciate the help.
