Need info on display?

Hi

I'm come in possession of some 40x6 characters VFD displays but I don?t know how to use them, and I cannot find any datasheet on them.
I think it's a itron display.
Can someone plz help me?

NICE!

is a lcd SED based controlers
maybe you can see lcd hype

good luck!

Nice display!

Very power hungry! 2.2Amps @ 5V!!!

Here is the datasheet:

Good luck with it!

Okay thanks for the informations.
One question more, how about driver, version 5.4 only support 4x40 characters?

Try this version:

Hmm need help, can't get the display to showing any things from pc,
Only in testmode, I?m pretty sure it's a wiring problem.

This is how I wired it:

Display | LPT
D0 -> 2
D1 -> 3
D2 -> 4
D3 -> 5
D4 -> 6
D5 -> 7
D6 -> 8
D7 -> 9
WR/RW -> 1
CS -> 16
Busy -> 11

BTW: The 6.0.0-b don't support 6 line

Try this:

Display | LPT
D0 -> 2
D1 -> 3
D2 -> 4
D3 -> 5
D4 -> 6
D5 -> 7
D6 -> 8
D7 -> 9
WR/RW -> 14
CS -> 1
Busy -> NC

You can select 8 lines or even 16, just use only the first 6.

Doesn't it have any serial connection?
I think that parallel is limited to 4 rows...

Ohh! okay I thought it should stand exactly on 6 line to act.

I've made the new wiring, now the cursor is moving randomly, but nothing is written.

Regarding the seriel connection, I can see in the datasheet it has a SIN/TEST port, but I'm not sure whether it's a normal rs232 or a TTL.
But it would be great if I could use seriel instead of parallel.

It is perhaps a little ambitious project for me, but could be cool if it succeeded.

I'd go with pin 25 T0/Sin.
It requires a level shifter for serial connection (some schematics can be found here too).

Baudrate is 19200 as mentioned on the datasheet.

Okay, I'll try with a max232 and see if it will work.

misimo · Post by **misimo** » April 6th, 2009, 1:49 pm

Now i have contact thru hyperterminal via T0/Sin port
Had to set baudrate at 4800.
There is some jumper on the board to set baudrate but I don't know how.

But I still can't get it to work in lcdsmartie, do I need a special driver to run it?

espectacular

you need a special driver i know

misimo · Post by **misimo** » April 7th, 2009, 11:00 am

And do you know where I can get hold of such a driver?

If I use the testdriver, the text is jumping all over the screen!

btw. One of the displays also has special Danish character

Post by **caesar** » April 8th, 2009, 12:00 am

Test driver must be set up correctly and it will work.

Look at the display datasheet for command characters and put them in testdriver ini file.

misimo · Post by **misimo** » April 8th, 2009, 2:55 pm

Okay I am totally lost,

Read the testdriver guide, but I do not understand it.

What will it take for you to do it

or perhaps to explain to me how I'm doing it.

If I just knew everything, I would't not bore you so much..

misimo · Post by **misimo** » April 28th, 2009, 7:08 pm

I've tried my best with the test driver but it still not running as it should.
If I have a text that Scroll, then it moves down to next line while it moves to the left.

Another problem. If I set the program to 16x40 lines, then it write the first 6 lines, after that it start for top and write the next 6 lines over the first, and so on?

I started to doubt whether I get this fine display to work
