My expertise is the detailed study of things as they are already implemented (reverse- engineering). I have a number of these displays and have studied the implementation. I have yet to study the software in detail (takes time) but expect I know a few tricks. Now the question: What do you want to know? What do you already know! I haven't compiled a FAQ, and am not aware of one on-line, so answers will be focussed on the finer points as required. A design was published in "Electronics Today" (magazine) in Australia some years back. Ah! I know who did it, 'twas Don, who is on this list, but it is not really current. He probably can quote the issue more easily than I, but whether you could find it in a library... Second try: A more recent offering in "Silicon Chip" magazine (again, Australian), February 1997. A stripped-down version, uses the same hardware (there are in fact, very few different ways to perform the task) and relies (totally) on a PC running DOS to work. You'll find it at http://www.oatleyelectronics.com/displays.html , fifth item on this page. Sorry, no on-line circuit. It's in the mag. -- Cheers, Paul B.
