Connection of colibri vf61 (iris board) with Keypad that has single output pin

Manmeet · January 27, 2016, 5:17am

i am using keypad that has only one output pin coming from keypad that i connected to the colibri vf61(IRIS 1.0) board on pin 24( ANALOG_IN1).

I have already gone through this link (High performance, low power Embedded Computing Systems | Toradex Developer Center keypad), but i am using our own keypad that has single output pin.

kindly suggest me an article having one output pin of keypad to the board.
