Not so happy to see this copy pasted in entirety by a dickhead I happened to meet super-briefly at a conference. http://d3cipher.wordpress.com/2011/02/25/borq-%E2%80%93-lcd-display/ . I guess I should add 'Author: ...' comments or copyright in every piece of code I put in public domain from now on.
