Took a crestron course a year or so ago (not sure the name), first two days was an overview and the next three days were programming in Simpl and VTpro.
In the in term i was using systembuilder but i have really noticed its limitations and want to get back into simpl programming. I am taking holidays between xmas and the new year and i have a bunch of inventory that i can program on. So my quesiton is where can i find some good literature to refresh my memory on this stuff.
Looked on crestron web page but cant find.

thanks in advanced
