In my product I am using ADP5585 KP controller IC and my circuit is like below figure,
now my query is,
1. I am not able to read R0xC0 configuration?
2. is nINT pin always shows high?
and I am able read KP IC slave ID but rows and columns not working, please clarify this.
I'm sorry but I don't have any specific reference code for the ADP5585 in Linux 3.12 other than the link to our reference driver's wiki page:
One common cause of false or missed events with the ADP5585 can be too much capacitance on the row and column pins. Are you by chance running long wires to the switches?
