At the LCD2USB project sources which use a earlier stage of the libraries from Peter Fleury i found that support for two controllers (which is actually only to handly two enable lines) was hacked in. Since there are some more nice functions i merged the changes necessary to support two halfs of the display to a newer version of the library from Peter.<br \/>\nThe result you can find attached.
