Library V1.24 to manage incremental encoder in your projects. This library as been build to simplify at the maximum  the user's work. It integrates the management of the interruptions functions that are compulsory to use with such objeccts. 
The combined use of this library and the library autom, enables you to "build" a very complete PLC,  able to manage a complex machine with digitized axes.

You will find the library and the documentation in the downloaded file


Library to transform your Arduino's module in an industrial PLC accepting Grafcet language. This library as been build to simplify at the maximum  the user's work. However it is not an automatism's course. On the other hand,  it could be an example on more C++ complex structures like pointed chains  and parameter's passages between function (procedural variables too).

Librairie to manage numeric files on SD


Library for managing.ini files on SD. V1.01

Tired of modifying sources files for a trifle, I started (sorry for the plagiarism of windows 3.xx) to implement on external SD card the parameters of my programs as simple .ini files. The IniFile library is in charge of reading these files and storing the information (key and Item)  in a table.


Librairie to manage images (for a due module)


The SD library presented here corresponds to the official library with a very small modification to avoid warnings from the gcc compiler in its "chatty" command option.
