OK. So basically any model of Ipac will accept at least 15 simultaneous keypresses in USB mode. Is that correct?

Also, are the maximum and minimum limits (which depend upon how many modifier keys are being used) the same for each model of Ipac? And what are the max and min limits?

Thanks

All I know is E-mail from 8 Sep 03:


--- Quote ---   So, is the limit 14 or 16 inputs?
   
   There have been many variations here, which is one reason I don't really mention a limit. The first version was 14 plus any modifiers. Then I increased it to 22 plus modifiers. It then went back down to 16 because I needed some buffer space for something else. I am thinking about increasing it again to 28 simply so that I can then state that there is no limit! As you mention, it does not really affect gameplay.

E-mail(s) from yesterday:


--- Quote ---Actually the figure of 16 still stands. In that figure I included one extra in the assumption that one modifier would always be used. I suppose this was not an entirely correct assumption but in general more than one modifier is used particularly if the MAME default keys are in use.

For the record the modifiers are:

Right
GUI

Right
Alt

Right
Shift

Right
Ctrl

Left
GUI

Left
Alt

Left
Shift

Left
Ctrl

Each of these is recognised in addition to the other 6 in a normal keyboard, and in addition to 15 on the I-PAC. All modifiers are sent independently so all can be recognised.
I really dont want that thread to turn into an Andy Vs Randy or Andy Vs anyone else for that matter!

Cheers

 The figure you sent in 2003 was 14 or 16 or 22 and you said you might increase it to 28 just to be done with it.

I wouldn't think there should be a lot of ambiguity about this particular specification on any encoder.  It only takes 1(!) individual to do the test and you'll have your answer first hand.

It's simple.  Just hook up all of the inputs (defined as keys as you are likely to use) to one side of the button and Ground to the other.  Press it while in a utility like Ghost key and watch what happens.  Be sure to push it a few times, but not too fast.  That's a lot of data to jam down the port at once.  You'll also want to see what's happening.

For a little extra fun, selectively disconnect a wire or two at a time to make sure that the encoder is behaving the way you expect it to.  Sometimes problems get masked if all of a ports pins or a large chunk of a matrix are activated at once.

BTW, if anyone wants to try this with a KeyWiz, leave the P1 UP input disconnected.  You can only do 31 keypresses at a time without activating the Shazaaam! feature.  If it was necessary to have all 32 down at once, a special version could be supplied without this limitation.

The GP-Wiz USB encoders could do all 32, but Windows wouldn't know what to do with a joystick pushed in all 4 directions at the same time  :D.  I have, however, designed a "stick-less" version where all 32 inputs could be active at once.  But it only works on Windows 2000 and up.

The ambiguity comes from the first E-mail implying that the firmware limit was changed at some point.

I guess my point was that an individual to whom this information is of interest need only conduct the simple test on their encoder and share their findings ;)
