Subject: Re: LCD code for recorder
From: Andrew Jamieson (ajamiesn_at_mira.net)
Date: 2001-12-29


According to the Solomon web site, they only have one (current) display
controller that uses an embedded ASCII table - the SSD1801. And this is
only in sample ...

I have requested the datasheet from them to see if the connections line up,
but a Solomon solution is looking unlikely.

Great! This comes very handy, since the LCD is something of a stepping stone
that unlocks a lot of other stuff. Being able to display information will
greatly improve the speed of discovery and development.

I'm guessing the tricky thing left to do is to figure out the command codes
used on the AJB6K display controller.

I'll be away for the week, so I don't expect to be trying anything with this
myself until next weekend. But I'm sure someone else will. :-)

Yes, the AJB6K has a character (rather than bitmap) display. It seems to
take
ASCII, or at least 8 bits per character. There is a translation table in the
firmware that indicates the display does not use normal ASCII.
