Hi!! I am a newbie to ARM7 microcontrollers, and i am going to work on the LPC2378. I have read a little bit on programming th microcontroller, and i can now comfortably flash LEDs. But, now i want to write a program that uses polling in LPC2378, such that when a particular input pin goes high, some function should be executed. Can anyone please help me out, coz i dont know how to read inputs in LPC2378(i know this is pretty dumb...but i am a total novice). Please let me know how one can read inputs from port pins ,using polling method, assuming my input device is a push button, and how can i possibly simulate this on Keil uVision3.
