'$15 VFDs'

In the 1/00 issue of Nuts&Volts, Resources Un-Ltd. has Futaba
2x20 VFDs for $15 or 3/$39. Model M202SD, serial or parallel
inetrface, 5V/350mA. The ad says drop in replacement for LCDs
but it is not clear if this means pin/code compatible.

I've dealt with their serial interface. It's easy, and only needs three
wires.

  Mike, I've been testing a Futaba 20 x 2 VFD engineering sample,
P/N NA202SD01BA2. I'm testing it with a 16F876 and I'm impressed with it.
It's actually easier to talk to than the standard Hitachi parts while it's
nearly 100% compatible. Some notes:

1. Like all VFD's, it's `power-hungry'... 450ma max, 350ma typical from a
single 5V supply.

2. Blue'ish-green display. Excellent luminance, contrast, and viewing angle.

3. Pin compatible with standard Hitachi-based LCDs (ie: Optrex) with the
exception of the contrast pin which is controlled by software in the Futaba
display. You can program 6 levels of luminance. You simply leave the
contrast pin (3) open. It has the standard 7 x 2, 14-pin pad layout.

4. Jumpers on the back for Motorola (Optrex), Intel, or Asynchronous Serial
interfaces. Motorola (Optrex) is default. The serial interface supports 9600
and 1200 Baud. Just add a RS-232 (ie: MAX232) interface and you have a
stand-alone RS-232 display. I've only used the default interface so far. I'm
looking at a `drop-in' replacement for a few projects where power is not a
problem.

5. 224 character ASCII and Katakana (say that fast eleven times ;-) character
set. Note, it only supports four custom characters since the other address'
are used for commands. Custom characters are not Bit-mapped like Hitachi
displays but it's still trivial to generate them.

6. No RS line! The commands are embedded in the character codes that would
normally be used for custom characters. Several commands accept multiple
parameters. The following describes the commands:

  Command (Hex)   Data Bytes      Description
  -------------------------------------------------------------------------
  03              6               Define user character.
  04              1               Set Display luminance level.
                                  0, 20, 40, 60, 80, 100%.
  08              N/A             Backspace.
  09              N/A             Horizontal Tab.
  0D              N/A             Clear the entire display.
  0F              N/A             Display character 7F (solid block) in all
                                  positions.
  10              1               Set cursor position (0 - 39).
  17              1               Dotted Cursor Control:
                                  Cursor Only; Data is re-displayed when
                                  cursor is advanced.
                                  Blink; Alternately display cursor and
                                  data.
                                  Cursor off.
  1B - 1E         N/A             Display User characters.
  1F              N/A             Software Reset.

7. The parallel interface is trivial. Just E and R/W. You don't have the
delays you have with Hitachi parts. Just send the data as fast as you want.
Note, the RS line must either be held High or disconnected.

  All in all, I think it took me around 15 mins to modify my standard LCD
routines. On the hardware side, all I did was remove the contrast pot and
hold the RS line High.

       Sounds great, how do I order? Does Resources Un-Ltd. have an address or
phone number?
