Title: parallel port logic analyzer software
Post by: Admin on May 31, 2010, 10:35:12 PM
Could be useful, if you have a parallel port . . .

Pretty cool, putting it on a pen drive to install on my old computer later :)

Could it made into analog reading?

But with an ADC, and some more code it should be possible?

Possible, just not with that program . . .

It would help if they had labeled the other pins (like where gnd is, etc)

Ground is 18-25. The '-' symbol.

Oh, i never knew that. I always thought the port had one V+ pin.

You can get 5V from the parallel port by stealing it from a data or control line set to "high" - but the current is limited.

Hi,

Too bad it doesn't run under DOS or Linux, because it will fail repeatedly in any Windows, as it doesn't run in Ring0 (so any other stuff the OS gives attention to will break the flow).
Don't use it for anything serious.
