Please find the new release of [b]embedXcode[/b] with the implementation of the self-documentation.

embedXcode • Jun 14, 2012 release 13
Installation Guide • Jun 14, 2012 release 9

Just add to your code and launch the Document target:
```
///
/// @brief	Blink a LED
/// @details	LED attached to pin is light on then light off
/// @n		Total cycle duration = ms
/// @param	pin pin to which the LED is attached
/// @param	times number of times
/// @param	ms cycle duration in ms
///
void blink(uint8_t pin, uint8_t times, uint16_t ms);
```
A help document is generated and closely integrated in Xcode.

Quick Help provides details on documented functions.

New version 14 of embedXcode brings a significant improvement on the size of the HEX and BIN files over the

embedXcode • Jun 25, 2012 release 14 • HEX and BIN files size optimisation

Sizes are now close to and even better than those obtained with the corresponding IDEs.

Sizes comparisons are available at http://embedxcode.weebly.com/hex-and-bin-files-size.html

Interesting! What changes did you make that resulted in smaller sizes? Is there a patch we can apply to our own build system?

I get better results adding an additional step and building an .a archive:
• first, gcc and g++ are used with -ffunction-sections -fdata-sections flags
• then, all .o objects are put into an .a archive with ar rcs file.a *.o
• finally, the linker is called with -Wl,-gc-sections,-u,main options
• for all, optimisation is set to -Os.

Interesting. We do have a library target that produces a libmaple.a (and we also use -function-sections -fdata-sections -Os when compiling and --gc-sections when linking). I wonder if the ar intermediate step has any effect on how well --gc-sections works.

Can you post the program you got these results for?

New! Installation Package

embedXcode is now installed with a standard installation package. Installation is faster and easier.

The Installation Guide and User Manual has changed for User Manual.

The package includes the templates, the code snippets, and the User Manual.

As Arduino 1.0 is now stabilised and wide-spread, should embedXcode continue to support Arduino 23?

Answer the poll at http://polldaddy.com/poll/6536674

Please note this is not going to affect other platforms, like chipKIT MPIDE which is still based on Arduino 23 and continues to be supported as it.

Thank you for your input. The poll opens for one week.

Please find the new release of embedXcode

[b]Oct 21, 2012 • Selection of pde, ino or cpp extension for the sketch[/b]

When creating a new project, select the extension on the drop-down list:
• Choose pde for Arduino 0023, chipKIT MPIDE, Wiring and Leaflabs Maple,
• Choose ino for Arduino 1.0 and Energia,
• Choose cpp optionally for a standard C++ file.

Using a pde or ino extension allows to edit the sketch with the standard IDEs of the boards.
