• Download and extract Eclipse IDE for C/C++ Mars.2
• Go to Help→Eclipse Marketplace
• Install Arduino eclipse IDE V2
• Install AVR Eclipse Plugin V2.3.4
• Window → Preferences → Arduino: Point to your Arduino IDE installation (V1.6.5 recommended)

• Create a new Arduino Project
• rename your .ino file into .cpp
• add #include <Arduino.h>

Now you are ready to go!
If you want to open this project in Arduino IDE, rename the .cpp file back to .ino

https://sublime.wbond.net/packages/Arduino-like%20IDE

This should be great, since it has the sublime autocompletion, which is really missing in the original Arduiono IDE.

I just found this project on github:
https://github.com/amperka/ino

for installation on Kubuntu 14.04 we need:

cd ~/programms
git clone git://github.com/amperka/ino.git
cd ino
sudo apt-get install python-pip python-jinja2
sudo pip install glob2 jinja2 pyserial configobj ordereddict argparse
sudo apt-get install python-serial
sudo make install

Here is the documentation for it:
http://inotool.org/quickstart

since ino wasn't supported any more, a fork of the project named „Arturo“ was created: https://github.com/scottdarch/Arturo

in this config file, which is not installed by default, we can set default settings. For me the most important one is the path to the arduino distribtion.

.inorc

[build]
board-model = nano328
arduino-dist = /home/karl/Programme/arduino-1.0.6/
 
[upload]
board-model = nano328
arduino-dist = /home/karl/Programme/arduino-1.0.6/
serial-port = /dev/ttyUSB0
 
[serial]
serial-port = /dev/ttyUSB0

Important: Don't forget to define the arduino-dist for both, the build and the upload command. Otherwise the upload command doesn't find the correct build-path, which as a suffix which is generated from the arduino-dist-dir.

Today I moved my ino-project to a new computer, and forgot to erase the .build directory. I got nothing-saying error messages like this:

karl@LackerServer:/xxxxxxxxxxxxxxx/yyyyyyyyyy$ ino build
Traceback (most recent call last):
  File "/usr/local/bin/ino", line 6, in <module>
    main()
  File "/usr/local/lib/python2.7/dist-packages/ino/runner.py", line 76, in main

    self.make('Makefile.sketch')
  File "/usr/local/lib/python2.7/dist-packages/ino/commands/build.py", line 216, in make
    ret = subprocess.call([self.e.make, '-f', makefile, 'all'])

    return Popen(*popenargs, **kwargs).wait()
  File "/usr/lib/python2.7/subprocess.py", line 679, in __init__
    errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1249, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

If we have an existing folder, with it's source files, we have to do a little adoption, so we can compile it with ino:
We need a defined folder structure:

projectpath/
  ./lib/
  ./src/
    ./sketch.ino

So the starting point of the project must be in sketch.ino.
Then we can run this:

:~/projectpath$ ino build

For uploading to the board we use

ino upload

Her is an example file structure after building the project

unlike as decribed here, which is a bit more complicated http://stackoverflow.com/a/5414566 we just add the permissions for the USB device similar to that of an Android decivce in Debug-Mode:

create a file /etc/udev/rules.d/51-avrisp.rules with

sudo kate /etc/udev/rules.d/51-avrisp.rules

enter this content:

# AVR ISP mkII (like an Android Device in Debug-Mode):
SUBSYSTEM=="usb", ATTR{idVendor}=="03eb", MODE="0666", GROUP="dialout"

save an close this file.

restart udev:

sudo service udev restart

unplug the programmer and plug it in again. now avrdude can be used without sodo!

an example call to avrdude could then be:

avrdude -U flash:w:firmware.hex -p m328p -c avrispmkII -P usb

• very interesting: PROGMEM and strings in flash with

   PSTR("My String in flash")

  
  access this string with

   pgm_read_byte_near(str+i) 

  , where str is the pointer given by a PSTR()-expression.

Here is a great article about this topic.

http://arduino.land/FAQ/content/4/20/en/can-i-use-new-and-delete-with-arduino.html
http://www.cplusplus.com/reference/new/operator%20new/

Most useful is the placement operator for static allocated memory.

#include <new> // very important, otherwise you get helpless compile errors!
#include "memorydispenser.h"
 
#define m(x) new (MemoryDispenser::get(sizeof(x))) x
 
 
// usage example:
JobController job = m(JobController(2));
