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

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
