Microcontroller interrupts are one of the big tools in our embedded programming arsenal. They make the chip listen for particular events, and once detected they stop what they’re doing and run a ...

We love interrupts in our microcontroller projects. If you aren’t already convinced, go read the first installment in this series where we covered the best aspects of interrupts. But everything is not ...

This article discusses Hardware Interrupts in Windows and how to show the boot menu in Windows. A video at the MSDN blog shows Windows booting real fast – under seven seconds. The computer used was an ...

If there is an interrupt present then it will trigger the interrupt handler, the handler will stop the present instruction which is processing and save its configuration in a register and load the ...

Traditionally programmers and organizations have had an irrational fear of using interrupts. One might think that statement is facetious but on more than one occasion in the last year the author has ...

A computer cannot meet its requirements unless it communicates with its external devices. An interrupt is a communication gateway between the device and a processor. The allocation of an interrupt ...

To see the interrupts occurring on your system, run the command: # watch -n1 "cat /proc/interrupts" CPU0 CPU1 0: 330 0 IO-APIC-edge timer 1: 11336 0 IO-APIC-edge i8042 4: 2 0 IO-APIC-edge 6: 3 0 ...

Nearly every embedded system uses interrupt service routines (ISRs). If you need to keep track of time, you likely have a timer interrupt that generates a system tick. If you have a USART, you’re ...
