I don't normally ask questions but I'm hooking a LCD colour screen to my Pic32!!
All's well but the "recommended" back light circuit looks a bit overkill... Why have they done this..
If I read it correctly there will be @1.25v at the base of the final NPN?? It is still saturated... So why the extra components.
