Title: Ipac question
Post by: pathdoc2 on October 17, 2003, 12:38:12 pm

Can the IPAC be programmed to send 2 keystrokes or keys rather than just one with a single button press.  I'm using an IPAC on a nonvideo/arcade project and I need to be able to program it such that pressing one button on the control panel causes 2 keys to be depressed (for example shift and the + key).  Can the IPAC do this?  If not I'll use a KE72 I have in another cab and put the IPAC into that game.
Thanks

Just hook two inputs to the same button.

If you need to have one button press and then the other press, in a reliable order, then put a decent size (at least 500 uF) capacitor between ground and the button that has to come second.

Right, but use diodes if you don't want to lose one input.  In other words - you can program 1B1 to LShift, 1B2 to +, and wire a button to both inputs, but if you also want to have a button wired to 1B1 that ONLY activates Lshift, it will activate now activate both LShift and +, even if only wired to 1B1, unless you use diodes.

for a picture of a circuit using diodes for the buttons
