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. He gives an ...

According to Dr. Alvarez, it all comes down to a simple principle: children love and need adult attention. But a kid who is constantly interrupting could be communicating that their brain is working ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
