Has anyone used a dot-matrix display? I have an LCD (128x64), model
no. HDG12864F-1.

I have previous source code but its so complex, i cannot understand
it. its poorly documented too. If anyone can share the algorithm
behind sending display characters to a dot matrix display.

What i want to do : 
some_function( "Display this" ) -> On the LCD: Display this

What I can do:
I can make a single for loop which has pointers to an array of hex
files mapped out to be characters. Result? each character display
reqiures a for loop. :(

Not too efficient on the big O notation. (Random sense)

Anyways, help? :P
