Hello, I am currently working with FRDM KL25Z board. I wish to write a code for object counter using interrupt. I don't know how to program nvic for this purpose. It will be of great help if someone provide me example code for configure nvic.
Note: in place of led and detector module I am using a switch for generating signal for detection of object. I am connecting this switch to pin 0 of port A.
Thanks in advance.
There are many examples for this board on NXP's website.
That would be good starting point.
