You can work with them right now, everything here work as long as you're aware of some Macro limitations. Which PIC do you plan to use ???

BTW, I'll take no credits, all the job have been done here and well done. I just put some of my spices in, some user configurables settings and some ease of use. It will be like my Keypad routine.

Still working on the final touch, code optimisation, documentation, some code example, basic schematics... fun job.
