Other Stupid Interrupt Tricks We can’t leave the “Good” of interrupts section without mentioning two particular patterns that we use in almost every project with an AVR microcontroller.

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.

On the lower end of the performance spectrum, many widely available and inexpensive microcontrollers pay for their small pc-board footprints by omitting functions. For example, most low-end processors ...

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 ...

How to manage dynamic power in a microcontroller using its non-maskable interrupt By Ajit Basarur, Shantanu Prasad Prabhudesai, and Nazmul Hoda, Ittiam Systems pldesignline.com (August 06, 2008) ...

Interrupts are the most powerful tool in the microcontroller arsenal because they directly answer the number-one concern with microcontroller applications: interfacing with real-world peripherals.
