I wish to write an interrupt based program for LPC2378 board. It involves one
of the two user buttons and the LED. Following is the algorithm for the program:
1.Choose a button
2.Set the relevant pin as the input
3.Check if the button is pressed
if yes - send an interrupt to the micro-controller which then lights the LED
if no - do nothing
I need guidance as to how to write an interrupt function in C, what are the
compiler directives, and what are the registers I need to deal with.
Any help would be greatly appreciated.
