- 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)
New Project
- 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
Sublime IDE
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.
ino/Arturo - The Command Line Interface
10.12.2014
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
Update: ino forked into Arturo
since ino wasn't supported any more, a fork of the project named „Arturo“ was created: https://github.com/scottdarch/Arturo
~/.inorc
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.
Error when moving host platform
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>

File "/usr/local/lib/python2.7/dist-packages/ino/runner.py", line 76, in main

return Popen(*popenargs, **kwargs).wait()

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
Compile existing project
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
Example
Her is an example file structure after building the project

avrdude and AVR ISP mkII with USB on Linux
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

Example Invocations
Arduino and size optimization
- very interesting: PROGMEM and strings in flash with
PSTR("My String in flash")
access this string withpgm_read_byte_near(str+i)
, where str is the pointer given by a PSTR()-expression.

C++ new operator
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));
