Interrupting while someone is talking is rude for humans, but smart for computers. [Ivan Voras] shows how to use interrupts to service the ESP32 analog to digital converters when sampling sound.

The Deferred Procedure Calls and Interrupt Service Routines is a mechanism in your Windows computer that will defer tasks of lower priority to a time suitable and simultaneously prioritize high ...

This paper will discuss design practices and guidelines that will maximize the efficiency of interrupts and interrupt handling in an embedded system IC. These practices can result in a smaller code ...

Just as you can often treat device registers as a memory-mapped struct, you can treat an interrupt vector as a memory-mapped array. In my last column, I suggested that you use casts sparingly and with ...
