I have been using adp5586 in one of my designs. I am not able to configure this is as keypad scanner.

As soon as I power on it will be as GPIO and when I change Register 0x3a and 0x3b all the rows will become high and all the colums will become low.


As per the datasheet when I press a key row has to become zero , then the key scanning activity starts.

But in my case my row is not becoming zero and instead column is becoming high . Am I missing anything?


Kindly help m at the earliest.
