Please find enclosed the source code of the LCD driver, as described in the
Application note. This code is for the IAR compiler.

Please find also some hints to optimise the contrast (usable for LCD with
different characteristics).


1. Output COMx high + inverted Port-buffer (as implemented) 
2. Insert Pause (to be set variable with timer). All COMs to "Low" and all
ports to "Low" -> no DC part 
3. COMx low + Port-buffer (as implemented)
4. as described in 2.

... same procedure for all COM-signals.

You can influence the contrast by the inserted pause.
