Hi,
I have connected 8 keys to single pins of adc. Now adc is continuously scanned & checked if any voltage level changes.
Normally its high means no key. & voltage changes as key is pressed.
Now I want that key is detected only once even if key is presses for long times. What happens when key is presses long time, multiple key is detected which I don't want.
Any suggestions on that.
I took code example from cypress - AN2034. & using MSP430G2553.
