Here's a picture that's really got quality,
IT LOOKS JUST LIKE THE WAY YOU WIRED IT!!!!
Now I'd caution you that most of the parallel ports on computers today
are built onto the board, so I suggest that you go out and buy an old card
with a parallel port on it, that way if ya blow 'er its not gonna cost
ya more than about $5 RIGHT!! (I know that your much too carefull to ever
blow a port on a computer, so am I, and I'v only blown two (PS COMMON YOUR
GROUND LINES [from experiance])
Here are the addresses for the signals drawn out on that incredibly good
diagram, described FURTHER DOWN.... :-)
Yes that's right one of those signals is the strobe, you see that strobe
line isn't like all the stobe signals out there, you see it DOSN'T go low
every time you write data to the data lines, its a bit of a port, like
any other bit of a port. The data lines are latched on the outputs, The
inputs arn't latched in any way form or manner, I dont rember if any of
the other outputs (like that strobe) are latched or not. Try EM!!!
Example of use in a basic program:
out(888, data)
Example of use in a C program:
outportb(0x378, data);
There are no spelling erors in this, my room is declared
as a seperete country in wich the rules of spelling are difrent. I don't
take responceability for you getting in trouble for taking apart other
peoples computers for partz. If ya blow your ports becuase of not commoning
the grounds, feel bad, 'cause i already told ya too!! I do make mistakes,
and if there is one in a schematic i have provided you have my permission
to write me a mean letter.
Back, need more be said?
