External Interrupts for chipKIT

Interrupts with chipKIT DP32

Jay Weeks of Digilent is back with another very useful “Instructable” about external interrupts. Armed with a chipKIT board, a USB cable, and a piece of wire, he guides you through some example code, so that you can see for yourself how interrupts really work! Using very simple explanations, he discusses polling vs. interrupts, and then he delves deeper into the topic to discuss debouncing, interrupt service routines, volatile variables, and more. Check it all out at Instructables.

Interrupt away!
