Multi digit 7 segement display library
I wrote this library out of 2 reasons:
- None of the existings libraries worked as expected.
- All existing libraries were bound to a specific timer.
As you may conclude out of this, you need to implement the timer yourself or, and this is what I did, use some of the existing timer libraries. I've been using "MsTimer2" (see the link below).
