I have been working on a project that has a set of fixed information shared between 2 Arduinos (one nano and one mega). This are essentially headers for information that is coming afterwards.
I would like to be able to update one list in a single file and then just upload into each arduino whenever there is a change.
I would think that using an include file would be the thing I needed but can't seem to find much info on how to use them, and even less for using them across multiple programmes.
or is going to be easiest to do as I have up to this point, but the windows next to one another, copy and paste/direct visual comparison. Both programmes will have to be re-uploaded when there are changes made to this list of definitions anyway.
