LCD Selection
Hey everyone,
I'm working on a project right now which monitors bearing
temperatures, oil pressure, and air pressure on a piece of equipment,
and if all conditions are satisfied will pick up a permissive relay
which will allow the machine to run.
I'd like to display all of this information to the user on a screen so
if there is a problem he/she can see immediately what is going on with
the system.
Problem is, I have about 12 different variables I'd like displayed to
the user and the LCD's I've come across such as those by Scott Edwards
(http://www.seetron.com) don't seem like they will be big enough to
fit all I want to on one screen.
I was wondering if anyone out there had interfaced a stamp to a larger
LCD or knows of a supplier for larger LCD's. LCD's that are as easy
to interface as Scott Edwards' are would be ideal. Probably don't
need anything as big as a 15" computer monitor LCD but maybe 6" or so
diagonal would be nice.
By the way, I have thought about using a button or something to switch
between screens but I would prefer to have it all on one screen.
Thanks in advance!

If a 2 x 40 (2 lines x 40 characters per line) will fit your needs, you can
find
them surplus at the Marlin P. Jones Web Site http://www.mpja.com using stock
number 11287 OP or hit the LCD Display Button on the Home Page. It's a nice
Densitron unit for $ 12.95 US and it should be Stamp compatible, although
perhaps not as neatly as the SEETRON Unit. New 4 x 40 units should also be
readily available from many sources including Densitron.

BTW, isn't it possible to use a Stamp only to control serial a less
expensive parallel LCD display and if possible with sort of an EPROM
connected to store some predefined words or graphics and another Stamp to
control the process?
Something like this http://www.controlanything.com/html/lcda128.htm but they
don't produce it anymore. I found it anyway a good product. I think it must
be possible to do the same thing with a additional Stamp.

How about cycling through each; display each variable for about
ten seconds? You could blink or lock onto one that is out of tolerance.

We have a couple of options. You could use our 40x4 alphanumeric serial
LCD module (http://www.hvwtech.com/lcd_4x40.htm) or you could go to a full
graphic module which would give you some added flexibility to make certain
values larger than others (you can download any font you want into it) for
emphasis (http://www.hvwtech.com/lcd_24064.htm)

One way to handle jobs like this is with our BOB-II video text overlay
module. The video output can drive a small LCD video display (LCD TV),
which can be substantially less costly than large industrial LCDs...
