Ummm... you should buy a book on C/C++. The little O'Reilly "Pocket Reference" books are nice and short if you are already a competent programmer.

Actually bought two today specifically for programming Arduinos.

digitalWrite(SLR2016_D, bitRead(msg[p-c], i));

^^^^That line....what does it do? I don't have a clue on what it does. Can't even make an educated guess after the last couple of days.

I have a happily scrolling SLR2016 today :slight_smile:

Thanks so much for the help! I would have never figured this out on my own. I learned a lot the last couple of days. This would have taken me weeks to get.
