Title: Erratic behaviour of controls through ipac
Post by: Martin0037 on April 22, 2018, 06:00:41 am
Has anyone had this issue?   I’m using an ipac4.  Been ok now for well over a year.  Occasionally I’m getting erratic movement on the player one joystick, mainly RIGHT  as in the player won’t go right at all,  then it works, then stops, then makes two movements etc...   weird.
 
It does this both in game (mame) and in the front end (hyperspin) so I’m assuming it’s an iPac issue somehow as on plugging in a usb keyboard it doesn’t do it.   Only does it on player 1 joystick too which is mapped to the arrow keys. It did it a week or so ago I noticed but on the UP movement. Now it’s doing it on RIGHT.

I’m using an iPac4 btw.  Checked all wiring,  continuity on everything is fine,  switches on joystick are fine also.  All grounds are correct etc.   Checked the iPac software to check everything’s mapped as it should be and it’s fine.
The green led on the iPac comes on and stays on, no flash error sequence or anything. I’ve also run notepad and tried all keys inc arrow keys and all is fine. 

Wondering if this is a pc issue or the iPac itself.

Any advice welcome.  Thanks.

Sounds more like a faulty switch.

Tested all switches.  All fine.  It’s intermittent.  Doesn’t do it all the time. I’ve disabled the “keyboard delay” function in hyper HQ to see if that helps as this function doesn’t appear to affect the player two stick on player one.   I’ll test some more and see if it’s made a difference.

Try swapping the wires on 2 of the switches around and see if the problem moves to that input.

Switches can intermittently fail.
If the problem does not move with the switch then its more likely to be the controller so then try swapping controller inputs.

I’ll try that. Cheers.

Switches fine.  Appears to be the “keyboard delay” function in hyperspin and when this is disabled it’s fine

Will test further...
