Objective:

In this tutorial we will discuss how to configure and use the LPC1768 external interrupts(EINT0-EINT3).
At the end of tutorial we will see how to use the exploreembedded external interrupt library.

EINTx Pins

LPC1768 has four external interrupts EINT0-EINT3. As LPC1768 pins are multi functional, these four interrupts are available on multiple pins. Below table shows mapping of EINTx pins.
