How to use interrupts on the LPC55S69 powered Okdo E1

In the last article, I summarized the process of enabling and using GPIO pins on the Okdo E1 by configuring the MCU in the MCUXpresso IDE. This time, I’ll enable pin interrupts that allow an application to react to various events.

How to use the GPIO pins on the LPC55S69 powered Okdo E1

Over the last couple of years, I’ve utilized a few different Arduino, Raspberry Pi, and other Linux based hobbyist development boards, like the BeagleBone Black, for many of my projects. I, however, never used other microcontroller boards that weren’t Arduino compatible. Recently, I started experimenting with the Okdo E1, a development board that’s powered by the LPC55S69, a very capable NXP microcontroller.
