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 ...

What is this System interrupts process? Do you see System interrupts consuming high CPU usage in Windows Task Manager? Is it a virus or malware? Well, System interrupts an OS process, and if it is ...

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 ...

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 ...

The 8051-compatible microcontrollers are equipped with up to two inputs that may be used as general-purpose interrupts. A simple way to increase the number of interrupt inputs is shown in the figure.
