Jay, thanks for asking these questions ahead of me, would have Had to ask
Rob all of these when I start the light project.
On that subject, does anyone have a good cheap source for LED's? Just spent
a bit of time browsing for some, but if any of you have already done the
legwork, it would save me some time, I am also looking for lighted
pushbuttons, square for panel and round for the 6 icp buttons, am also
looking for acceptable military type knobs to fill the gap until we can get
affordable subs for the real ones.

Subject: RE: [simpits-tech] MM5451 LED Driver
To Robert or anyone out there, could you give a brief description of how
this circuit works and will it work on a slave machine networked to a main
box running Falcon or must it run on a host machine running Falcon? Can it
run on a slave machine with Falcon mem-reader running? There are 2 chips
listed on the spreadsheet, are these two different circuits? Do they need
two different parallel ports? Two different computers? Where does one
locate these chips? Digikey? Mouser etc? The pin assignments for the LEDs
are not really the pin of the chip, but the listed outs 1-35 listed on the
circuit? Are there any resistors that need to be used with these LED's?
What voltage LED are the best for this circuit? The capacitor, can it be a
generic ceramic disc capacitor or does it need to be tantalum, electrolytic
etc. type?
I'm not trying to be a butt with all the questions, goodness knows my
pants are going crazy for the fact that someone knows how to do this and is
willing to share it with others and now one less thing I have to figure out
(and would probably have a hard time doing it since I don't know anything
about programming).
Thanks
Jay

No problem Mike.
Ok.here we go.I've uploaded the program to the ftp server (Falcon2_4.zip).
The installation instructions are fairly simple.put the vbio.dll file into
the \windows\system directory, click on the Falcon2_4.exe program to run. I'
ve also included an excel spreadsheet that lists which lights are on which
pins. Questions are welcome
Rob

Thanks Rob, I may ask your help on this as I move forward, no heavy
bugging though :)

Yup.I'll put together a zip and post to the server.

Rob,
no idea how to code, maybe I will have to learn some if I must, do you
already have a program written to for the w/ 5451 to interface w/
Falcon?
Thanks

Ok folks.I've uploaded (circuit.jpg) the circuit diagram for the 5451
LED driver to the ftp site. In a single chip configuration, the chip
connects to pins 2,3 and 18 of the parallel printer port. As always, please
be careful in working with ports on your PC. If anyone needs help with the
code portion, I can only help if you're interested in VB. Also, my code
requires the use of a 3rd party driver called VBIO (it's free, and I believe
I have a copy somewhere as well). When I last played with the code, I was
running a Win98SE PC, so I haven't tested on any other OS.
Rob

uploaded (circuit.jpg) the circuit diagram for the 5451 LED driver to the
ftp site. In a single chip configuration, the chip connects to pins
2,3 and 18 of the parallel printer port. As always, please be
careful in working with ports on your PC. If anyone needs help with
the code portion, I can only help if you’re interested in VB. Also,
my code requires the use of a 3<SUP>rd</SUP> party driver called VBIO
(it’s free, and I believe I have a copy somewhere as well). When I
last played with the code, I was running a Win98SE PC, so I haven’t tested
on any other OS.</SPAN></FONT></P>
