16x2 Cyrillic LCD available in USA?

[larwe]

I'm looking for a small number (2-3) of standard 16x2 LCDs with a
Cyrillic character ROM and the standard 7-wire/11-wire Hitachi-style
interface. Backlighting is not important, and I can make do with
almost any size. Standard Roman LCDs don't have enough user-defined
character spaces for my needs.

Ideas?

Didn't some of the Hitachi-chipped displays have user-defineable characters?

Yes, it's documented in the controller datasheets (sometimes); however
I have not found any module on the market that has a pure-RAM
character generator. All of them have mask ROM plus a _few_ user-
defined characters. Not enough to make up the different/missing
letters.

"From" sovok?

I have no cultural affiliation with Mother Russia (the closest I get
is that I want to take a tour of Pripyat).

I've simply been asked to mock up a Russian version of something that
currently uses a 16x2/5x7 LCD.

Hi,

LCD producers have a portfolio of a certain number of ROM resident
font sets.
Therefore I see here two ways:

1. Find a supplier that has already produced an LCD with the Cyrillic
font set.
In this case, you pay just the 3 pieces you need.

2. Place an order to a supplier, for custom LCD with the required font
set.
If you buy at least 2000 of these custom LCD, the supplier won't
ask you the money for the tooling.

Not located in the USA, but should be no problem to get.

Have a look at http://comet.bg , search for "LCD". The first of the
LCD
modules (fifth on the match list) returned this data sheet:

http://home.comet.bg/datasheets/LCD/AC-162B.pdf .

You can either figure out a way to buy from Comet in Sofia
or find your way to the Taiwanese manufacturer directly.

Just an idea.. In true Russian style why not construct a complete new
display from dot matrix LED modules. Totally impractical I know, but oh so
typically Russian.

The other daft idea was to disconnect the controller and put in place your
own.

As I said, a bit daft, but more to cross off the list when presenting to
Exec. You know, for some reason I thought that the Hitachi interface
allowed the whole character set to be reprogrammed on the fly.

Is it possible to redefine a character, print it, and then redefine again.
What I mean is, once the UDG is on the screen, can you then go back and
output another.

Apologies for not being able to offer any solid answers.

I have one I pulled from an old laser printer (NEC silent writer 800 or
something, I know it had a big board with a 68000 and a whole bunch of
ROMs).

The custom code on the HD44780 is A67. This particular one is EL backlit.

No, I assume it refetches the character each scan. This can be used to
useful effect when designing bargraphs, strength or charge indicators; the
last Batron I used had only 8 UD characters (standard, I think) and I needed
two strength indicators. I just wrote a routine in the ucontroller to
redefine a pair of characters as required - so out of 2 characters I got a
six point signal indicator...

Using only my steel dentures and solder reclaimed from stolen military
electronics, melted over an open fire?

I'm looking for a drop-in replacement (more or less) for an existing
circuit, where I can just wire it up, change a string table, and be on
my way. If I'm going to have to go to significant trouble, then I'll
just use a graphic LCD.

Exec. You know, for some reason I thought that the Hitachi interface
allowed the whole character set to be reprogrammed on the fly.

I'm aware of LCD controllers that offer a RAM-resident CG set for the
whole font table, but I've never seen one in the wild (probably
because it would waste so much ROM space in the host side of the
equation). All the standard controllers only let you redefine a few
characters, typically 16; the remainder are mask-ROM and you're given
the option of a custom mask run.

Is it possible to redefine a character, print it, and then redefine again.

No, the controller doesn't work that way. It's not like UDGs on the
Spectrum (are you the same Aly as in c.s.s?) which are really just a
fancy way of accessing a fully APA display.

Weird! How do you know it has Cyrillic CGROM? (Or, was that
information implicit in the ROM version?)

Thanks for that one... I have found several similar vendors selling
such products, but as yet have not successfully made contact with any
of them.

Hmm. Suddenly, I wonder if Olimex might be able to help.

Wow, I bet you can help if my next project requires a character LCD
with Klingon CGROM?

Ok, I went to Google Groups and it reeally shows as garbage even
original Vladimir's post. In my Thunderbird it shows fine in both -

Oh, well. Year 2007, Unicode and all that buzz around it and they still
cant get it right.

What does it mean? I didn't think I knew any Russian beyond da, niet, and a
few words picked up via Nadsat in 'A Clockwork Orange', but that one is
definitely familiar somehow, but I can't remember why.

nm, I went Googling.. I'm interested in whether it still has a formalised
use though.
