VFD MODULE from FUTABA M202SD04BA

Dimas · Post by **Dimas** » January 8th, 2007, 1:10 am

I'm looking for information about this module, that have 13 pin interface and 20x2 charcter in a matrix fashion. This is hard to find, I don't know why FUTABA work in this way, so complicated for various of their MODULES

It's too difficult to help you only with these info

The only tip I can give you is to search for any chip number on your display and with this as a a guide to start searching the web.

Thank you Limbo. The controller Chip is the 5P0 0A002 subindex 04, now I'm looking for it. There are two OKI C1163 and one OKI C1164. The controller have a memory with the version number 00708 (I think that is a memory).

I Found the answer, BUT LCD Smartie can't work with this VFD because this VFD don`t have Register Select, the memory map is continous, I need to write my own driver for this VFD. One question, LCD Smartie is programed in delphi?

Yeah correct... are experienced in delphi?
we always need for programmers to give us a hand out there....

Hay Limbo, well now i`m programming on Visual Basic 6 and VisualBasic.net, But I`m learning Delphi. In the University we always program on C/C++ (Builder) but in some cases I use the others. I like C++, not Pascal but no problem. I`m finishing my career of Electronic Engineering here in Argentina (sorry about my english). I wish to cooperate with LCD smartie but a need some information and time to learn about DLL programming.
Now i`m working with a Graphics LCD from Winstar (cheaper

) 128x64`pixels. Well that's my history.
When get some photos I will place on the forum

.

Demos in many languages can e found on main LCD Smartie site (downloads section).

You can use them and fing what is fitting to your needs (and knowledge)

You can also examine the source code from the site... I you think tah you are experienced enough to develop this program we will talk again (Send PM for details)

Dimas... are you sure it's a 13 pin connector? I have a similar model (M202SD04AA) that uses a 34 pin connector... and 1/2 of those pins are connected to ground. 1/2 of 34 == 17... not 13. I contacted Futaba's customer support email... and I was able to get the datasheet on this display. I will put the pinouts below.

Pin 1 = D7
Pin 3 = D6
Pin 5 = D5
Pin 7 = D4
Pin 9 = D3
Pin 11 = D2
Pin 13 = D1
Pin 15 = D0
Pin 17 = /WR
Pin 19 = A0 / /RTS
Pin 21 = /RD
Pin 23 = /SEL
Pin 25 = /TEST
Pin 27 = BUSY
Pin 29 = /BLANK
Pin 31 = /RESET
Pin 33 = RXD/TXD

Note 1: This is a combo-function VFD... it will do both Serial and Parallel interfaces. Pin 33 is N/C in parallel implementations.

Note 2: ALL EVEN NUMBERED PINS ARE GROUND (GND)

Note 3: There is a separate 3 pin power connector. The pinouts are as follows:
Pin 1 = GND
Pin 2 = +5V (VCC)
Pin 3 = GND

Note 4: I have this display connected right now... however, since I only use Linux... and I am, temporarily, stymied for software to control this VFD.

Note 5: I have connected the display as follows (and have gotten the single blinking curser):
D7-D0 == Parallel Port pins 9-2
/WR == Parallel Port pin 1 (Strobe)
/SEL == Parallel Port pin 13 (Select)
BUSY == Parallel Port pin 11 (Busy)

I am not sure how to connect pins 19 (A0//RTS), 21 (/RD), 25 (/TEST), 29 (/BLANK), and 31 (/RESET). Any advice on this would be appreiciated.

P.S. - If you want the datasheet... email me at Lyos.GeminiNorezel@gmail.com and I will email you a copy.

Hello LyosNorezel...
I think that your connection is OK, but you forgot the RD Signal

Parallel interface require Data Bus : D7..D0 (IN/OUT)
Write: WR (IN LCD)
Read: RD (IN LCD
Chip Select: SEL (IN LCD)

8 Data Lines and 3 lines for control the Bus.

You can connect RD to Busy of your Parallel Port and Busy of the VFD to another input pin (you have 5 input in the standart parallel port)

The BLANK signal may be for chek if all the dots are working
like a Lamp Test signal of the 4511 BCD to 7Seg Decoder.
The VFD can work whit this pin cennected to propper point.

TEST may be an output so you can leave this pin open.

RESET like a master reset i think.

mail me the data sheet to answer with more detail, but don`t worry because you are able to use your VFD without troubles.
