The sequence of importance assigned to interrupts. If two interrupts occur simultaneously, the interrupt with the higher priority is serviced first. In some systems, a higher-priority interrupt can ...

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 ...

Embedded systems are deemed real-time if they will suffer a failure when a critical system event cannot be serviced in the required time, and for many embedded systems this time limit is very short.

Interrupts are a major feature of most embedded microcontrollers and effective real time response to interrupts is vital in low power systems that often rely on a ‘run fast then stop’ approach to ...

Whether an embedded system is a handheld Internet device, a telephone switch, or a complex aircraft control setup, the real-time operating system (RTOS) running it must guarantee uninterrupted service ...

As a fully preemptive kernel, SST must ensure that at all times the CPU executes the highest-priority task that's ready to run. Fortunately, only two scenarios can lead to readying a higher-priority ...

This application note presents the RX family of microcontrollers on using multiple interrupts. The document includes the specifications, the operation confirmation conditions, the hardware and ...

What’s the biggest difference between writing code for your big computer and a microcontroller? OK, the memory and limited resources, sure. But we were thinking more about the need to directly ...

I’m not a big believer in reading about other people’s work habits. That’s probably why I rarely write about mine. I mean, just because something works for me doesn’t mean it’ll work for you, right?
