In designing µC-based systems, you often face a situation in which the µC has to respond to an external event happening at an uncertain moment in time.

Interrupts are the name of the game for more functional microcontroller firmware. [Rajendra] just posted a tutorial covering all of the interrupt types for the PIC 16F688 microcontroller.

The Good Side of Interrupts Interrupts allow your microcontroller to fire off specific “subroutines” when various events happen.

Edge-triggered interrupts are useful in microcontroller (MCU) applications for processing asynchronous events like switch closures, level transitions, and pulses. However, low-cost MCUs offer ...

A primary goal in the design of this 8-bit microcontroller was that it support fully deterministic software execution; that is, every instruction would execute in a specific, predictable amount of ...

However, a project occasionally requires that several interrupt-service programs must process multiple external interrupts from various sources. Cost and inventory constraints may make it undesirable ...

Riding the PC/104 bus in the company of a PIC18F8722 microcontroller from Microchip Technology, the MC104P controller module provides access to external memory and interrupts in the same manner as ...

10 Pain-Free Steps to Configuring an Interrupt Controller Setting up interrupts properly on a microcontroller isn’t easy. Thankfully, there are steps that can be followed to alleviate these painful ...
