IPAC2 and switches/push buttons
« on: February 04, 2015, 03:37:16 pm »
Hi:

I know that connecting a push button to and IPAC2 card, makes possible to send a pressed key every time the push button is pressed. But, would it be possible to connect a switch (on/off) and have only 1 pressed key sent (instead of conitnuously sending the same key) whe the switch is in on position?

Thanks in advance,

The IPAC will not do this but the U-HID board can be configured to send a short "pulse" of any key: www.u-hid.com

You need a debouncing circuit. They're fairly simple in design.
