Keeping the eclipse project compatible with the IDE
The compatibility between the arduino IDE and the arduino eclipse
plugin can only be guaranteed from the Arduino Eclipse Plugin to the
Arduino IDE and not the other way around. Currently the arduino
eclipse plugin is out of the box not compatible with the Arduino IDE.
The incompatibility is caused by the fact that the arduino eclipse
plugin works with C++ files only. The arduino IDE can handle C++ files
but needs at least one ino/PDE file (for amongst others) to identify
the classpath.
To be able to compile your code directly in
the Arduino IDE you need to do something extra at three common actions
during Arduino code development
1) After installation tell Eclipse to process ino(and/or pde) files like C++ file 2) After
creation of a new sketch project rename the created cpp file to ino
(or pde if you are using a Arduino IDE version below 1.0)
3)After inclusion of a library add an include of the library to the ino
file (Do not include it in a header file but in the ino directly.).
That is all which is needed to be done to create project that are
Arduino IDE compatible.
When you want to compile the project
in the Arduino IDE select file open. Goto the Eclipse workspace
folder. In the workspace folder there is a subfolder with your project
name. In that subfolder you will find the .cpp file you renamed to
.ide or .ino. Select that file and compile.
And here are detailed instructions on how to do this
After installation tell Eclipse to process ino like C++ file
In the menu select Windows ->preferences In the section
C/C++ -> file types press new enter *.pde and or *.ino as
filename and C++Source file as type.
After creation of a new sketch rename cpp file to pde
Right click the .cpp file created by the new arduino sketch wizard
select rename change the .cpp to .ino or .pde
After inclusion of a library add an include reference to the
library to the ino or pde file.
In the ino file at the top add a line that looks like #include
< [the imported library].h >
