There's a small problem with uploading too, for some reason the port for AVRdude to use gets lost somewhere. Changing AVRDUDE_PORT in Avrdude.mk to $(BOARD_PORT) fixes that.


That's strange, AVRDUDE_PORT is defined in Avrdude.mk by:
Code: [Select]
AVRDUDE_PORT      = $(firstword $(wildcard $(BOARD_PORT)))
with BOARD_PORT defined in Arduino UNO.xconfig by
Code: [Select]
BOARD_PORT = /dev/tty.usbmodem*
or in Step1.mk otherwise by
Code: [Select]
ifndef BOARD_PORT
    BOARD_PORT = /dev/tty.usb*
endif
Arduino UNO.xconfig has priority over Step1.mk.

Board_port is pulled from the config file fine, but "$(firstword $(wildcard $(BOARD_PORT)))" seems to return nothing, making AVRDUDE_PORT blank. Without $(firstword $(wildcard it works fine.

Hi again, I've discovered another problem, but unfortunately my makefile writing skills aren't up to scratch to fix this one.

For some reason the Step2 makefile is losing the USER_LIBS_LIST. USER_LIB_PATH works for me when in Arduino.mk I change 
Quote
USER_LIB_PATH  = $(wildcard $(SKETCHBOOK_DIR)/libraries)

to
Quote
USER_LIB_PATH  = $(SKETCHBOOK_DIR)/libraries


However, for some reason USER_LIBS_LIST is always "0" in the debug info. Any ideas? The only way to get non-core libraries to compile is to enter their full path into the source.pde. Thanks!

Just open makefile
Code: [Select]
# Libraries
# ----------------------------------
# Declare application Arduino/chipKIT/Wiring and users libraries used
# Short-listing libraries speeds-up building
# Typing = 0 takes none
# Otherwise, all will be considered (default)

you can define which Arduino/chipKIT/Wiring libraries you want
Code: [Select]
# List Arduino/chipKIT/Wiring libraries here
#

as well as which users libraries
Code: [Select]
# List users libraries here
#

Those parameters are intended to avoid compiling all the libraries each time and thus, speed-up the process.

Ah that's great, thanks :)

Perhaps it'd be better to have an environment variable set in Xcode defining whether you want to compile user libraries or not, would be much easier than changing a list in the makefile. You could have the envar as a list of user librares too.

Feel free to skip APP_LIBS_LIST and USER_LIBS_LIST from Makefile and add them to Project > Project > Build Settings > User-Defined.

The real challenge is to obtain documentation about Xcode inner structure and keywords to improve:

  • the template sets the sketch as c++ code and not plain text, for code-sense

  • the template populates the Sources List for code-sense

  • instead of having the serial console in a separate Terminal window, integrate it in Xcode debug pane

  • ...

New releases add Wiring and LaunchPad support.



embedXcode • Apr 05, 2012 release 7 • Wiring and LaunchPad platforms added
mpideXcode • Apr 05, 2012 release 10 • Wiring and LaunchPad platforms added

Code is here and documentation there.

Both build and upload have been successfully tested on Wiring S and LaunchPad msp430g2452 boards.

Energia is the Processing-based IDE for the LaunchPad platform.

Critical Decision Ahead

Most of the open points on embedXcode are about Xcode, especially keywords on the template.

Despite numerous calls for help, they're still unresolved. The Xcode template remains undocumented and there's no sign of openness from Apple. Apple seems to restrict Xcode to OS X and iOS platforms only.

So I'm considering to change for another IDE, with NetBeans as most probable solution. It's open, and documentation is available.

What do you think?

There are people attempting to unravel the template format (why Apple had to change it in Xcode 4 to this weird new system we'll never know) for coding other projects too. You aren't alone in trying to decipher it, but only asking for help via the Arduino on Xcode project means the audience is pretty small. I'm sure someone will figure it out (or it'll get leaked from Apple) sometime.

You're right that Xcode is really designed for OS X and iOS, Apple has little interest in supporting other languages/platforms. Despite its limitations though, I'd personally rather use Xcode. NetBeans is Java, which is usually pretty clunky and un Mac-like. I don't have experience with anything but the Arduino IDE, and Xcode on the Mac however.

Elijahg,

You're right about selecting the right channel for the right audience.

I'm posting on both Xcode-related forums --of which Stack Overflow for very specific questions about the Xcode 4 template-- and embedded computing related forums.

The idea is Arduino users may be interested in using Xcode and Xcode experts may have some tricks to exchange.

Thanks to this strategy, the Wiring and LaunchPad platforms are now supported by embedXcode. I hope adding more platforms may help raising interest on this project.

There are so many things one could dream about: built-in serial console, integrated help, debugging, closer integration of the tool-chains, ...

Please find the new releases for

embedXcode • Apr 16, 2012 release 9 • Code-sense reference defined by selected board
mpideXcode • Apr 16, 2012 release 12 • Code-sense reference defined by selected board
Installation Guide • Apr 16, 2012 release 6 • General update

All the manual settings are due to unknown template keywords. Your help is greatly appreciated.

embedXcode now supports Maple!



embedXcode • May 23, 2012 release 10 • LeafLabs Maple implementation
mpideXcode • May 23, 2012 release 13 • LeafLabs Maple implementation
Installation Guide • May 23, 2012 release 7 • LeafLabs Maple implementation

The Maple reset script --which sends control signals over the USB-serial connection to restart and enter the bootloader-- is written in Python and requires the PySerial library:
• Read the instructions at http://leaflabs.com/docs/unix-toolchain.html#os-x and
• Download PySerial library from http://pypi.python.org/pypi/pyserial.

Full documentation and download are available here.

Enjoy  :)

As embedXcode manages multiple platforms, including the right libraries and dealing with syntax specificities are two cumbersome challenges.

Until now, the platform identification was solely based on the MCU, resulting on lengthy #if #elif #else #endif statements.

Now, embedXcode brings a new approach based on the IDE.

The Arduino, Wiring and Maple IDEs set an environment variable for the tool-chain.

For example, Arduino defines ARDUINO=100 and pass -DARDUINO=100 on to gcc, g++ and alike, Wiring sets -DWIRING=100 and Maple -MAPLE_IDE.

So the code is fully compatible between embedXcode and those IDEs. This new approach brings more compact and easier to read code, and doesn't require maintenance at code level when a new MCU appears.

This new IDE-based approach is optional, as not all IDEs include this approach. Let's mention Energia and chipKIT MPIDE, and hope they consider it!

As always, full documentation including features, tutorials, installation guide and code, is available at embedXcode website.

Enjoy ;)

I'm working on the next release of embedXcode. I plan to integrate an automatic documenting feature.

After having reviewed HeaderDoc, doxygen and appledoc, I picked doxygen.

Integration with Xcode is the main challenge. The idea is to select a specific target to build the documentation, obtain a PDF and integrate a codeset Xcode could use.

There's still a lot of work to do.

Stay tuned  ;)
