'HELP INTERFACE VFD. THANKS'

Hello

I have the opportunity to find in France some VFD displays 1x16 for 3$. I
look for an interface chip  to manage this display. Which are the integrated
circuits most standard for this application and where can I find examples of
code?
Do exist chips compatible with the 44780 used for the LCD?

Help is welcome.
If you already encountered problems with the VFD, thank you to share them
(useless to reinvent the wheel!).

Thanks Peter,

I will have a look to this chip. Do you already use it ?

Yes, we are using it in our VideoCD players.

It's a fairly common and high volume parts and
you should be able to get it around US$1.

On top of driving VFD, it also handles keyscan.
Programming is thru a NEC proprietary 3-wire interface.

Thanks for answers.

I saw the datasheet but as you said, it's a proprietary 3-wire interface, and
the most important it is not compatible with 44780. I'd like to switch
easily, for low cost LCD and for "luxe" VFD without having to change my
program.

Thanks,
SP


Speak is a way to learn.

If I read you correctly, your VFD is "dot-matrix" type as
oppose to "segmented" type ?

In that case the NEC 16312 can't be used here as it is
designed to drive segmented type VFD.

Samsung makes VFD module that is pin to pin compatible
with standard 44780 LCD modules, it even has built-in
inverter so that you only need to supply it +5V.

Check out, http://www.sdd.samsung.co.kr/

However, I have asked the price before, a 20x2 VFD module
cost around US$30 compared to 20x2 LCD module of only
around US$8. It does look neat though.

Peter Tiang

Hi Peter,

I am very happy for your solution (samsung). It's exactly what I looked for.
Just a little problem, I went to their site but impossible to find a europeen
distributor. May be someone from the list have an adress ?

Again thanks Peter

Hi SP,

You can try their Semiconductor distribution channel in Europe

   http://www.intl.samsungsemi.com/top/contactus/Distributors/Europe1.htm

We got ours from Enzer, http://www.enzer.com.sg
