I was looking ADP5585 chip and it looks like it is going to fit in my requirements. It has 5*5 keypad configuration.
I need only 6 keys in my design. It does not matter if two is R and three is C or vice-verse.
How can I use ADP5585 if I want to use only 6 keys?
If you have better chip for my design/purpose please suggest me.
I will really appreciate your help and support.
The ADP5585 interfaces with the microcontroller via I2C. The ADP5585 interfaces with the user by either GPIO mode, KP mode, or special pins. If you setup the ADP5585 to accept GPIO signals, the ADP5585 will still report the results to the microcontroller through I2C.
