Embedded systems rely on interrupts to tell a processor when something needs service. Often, the system's response time to an interrupt is critical to proper operations. To learn how well your ...

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 ...

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 ...

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 ...

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 ...

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?
