tuto: how to use Arduino-Uno with the same Pin name

Mark suggested me this little tutorial that allows with a very simple file "Arduino-uno - pin.inc" to use the names proposed by Arduino.
I believe that Ben Zijlstra had already made one but I did not found it. (I'm confuse Ben Embarassed

)
This allows to better translate the examples and programs written in C-arduino.

Here the inc file, in the added files 2 samples (ledon/ledoof and the Ds3231 clock using I2C pin)

Thank you Jean-Pierre,

I think this will make things easier.

And what if the the arduino PINx is used as input, you need to change the PORTD.x to PIND.x ?

that is an option.
another option is to add an alias.
I guess the users of this file can inform us about it?

Yes Evert you are right, but in this case it is easy to change the .inc file

Thank you for the remark. I change a line in the post
