LCD again...

Hi all,
One more question about LCDs...
I've got a display module from Trident. It should be a TRIMOD S 1537, 2
lines of 16 characters.
I've played with other modules, with a 14-pin connector. But this one has a
16-pin connector.
I think the 2 additional pins are connected to the optional backlight (they
are connected to 2 other points on the module, marked 'A' and 'K', so I
suppose it's for the LED backlight, when instaled).
If this is right, may I use the 14 first pins like a 14-pin model (1 = Vss,
2 = Vdd, 3 = Vo, 4 = RS, 5 = R/W, 6 = E, and 7 to 14 = D0 to D7) ?
My second (and last...) question is : is there a way to program custom
characters like on the serial display from Parallax (Scott Edwards) ?
If somebody has the datashet (or it's address), I'd like to have it too.
Many thanks,
Phil.

Yes, that's correct.

You can generally drop customer characters into any HD4480-compatible LCD.
To make the process easier, I wrote a program called LCD Character Creator
(check out the September issue of Nuts & Volts). Anyway, the program let's
you create custom characters and gives you code samples to make the process
work.
That program will be released next week. Check the Parallax web site for
details.

power to the pins or you will smoke the backlight. Most displays require
either a dropping resistor *or* a diode in series with the backlight power.
Generally, the first 14 pins work the same way on all displays, and the last
two are backlighting. Insult the documentation to be sure.
As far as the custom characters, if the display has the Hitachi chipset, you
should have that capability, although the commands are different than with
Scott's module. There is a good article on this in the Nuts & Volts of Basic
Stamps volume I.

Thanks for your ffffast answer !
Unfortunately, I think I can't read Nuts & Volts, because I'm living in
Belgium. So I'll wait for your program to be available on Parallax's site.
Anyway, thnaks again for your informations !
Best regards,
Phil.

Thanks for your attention. I'll start playing with this module tomorrow, I
think it's to hazardous now (00:25 AM in Belgium...)
Best regards,

European vendors?

Philippe:
I just spent a week in Belgium working with your wonderful technical school
system to introduce BASIC Stamps in the classroom.
I had a great time and sampled many wonderful beers.
You can get "The Nuts & Volts of BASIC Stamps" (2-book set) from Antratek
Electronics (www.antratek.nl). They are the Parallax distributor for Holland
and Belgium. And they're really nice people who will happily help you with
all your Parallax product needs. The books will be a great resouce and there
are several LCD articles included.

Did you try beers like 'Chimay', or 'Bush' ? They are very good, but don't
drink more than two... :-)
Hopefully, our beers are much better than our weather...
I'm happy to see that the Stamp begins to be known in Belgium. The first
time I asked about it to my favorite electronics shop, the girl was looking
at me as I was speaking chinese ! Did you go to a school in Brussels, or
elsewhere ? I'm from Charleroi (60 km south from Brussels), and I think I
must be the only guy playing with the Stamp in this area...
Thanks for the info about Antratek, I'll have a look on their site.
Best regards,
Phil.

1-14 are the same.

I wonder if Parallax could help distribute Nuts & Volts through their
European vendors?
