How do I eliminate the rebound effect due to ...

[mabauti]

pushbutton rebound software

the pushbuttons? (specifically in this circuit) I'm using those PB's for interrupt service

 

[mabauti]

any idea?

OK. I give up :[

Any moderator please close this thread.

you can eliminate switch bouncing either by hardware: each switch needs to be connectec through flip-flops (search the net) or by software by defining a dead time each time you push a button (assuming that one cannot push a button twice in les than, say, 10msec or so)

Hi,

I think you can try "Debouncing techniques", don't consider any input changes upto 10 msec. Assume that two keys are not pressed within 10msec.

If you need more details, contact me.

Try to put a capacitor near each PB. It will delay at some times depend on the capacity. Or use MAX6818 for switch debouncer.
