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 ...

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 ...

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 ...

As Arm-based infrastructure continues to scale across markets, demands on system components increase. This can mean more interrupts, or signals from hardware/software to a processor to pause a task ...

When a WFI instruction is executed or when the processor enters sleep mode using the Sleep-On-Exit feature, the processor stops instruction execution and wakes up when an (higher priority) interrupt ...

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 ...

Endian format refers to how multibyte variables are stored in a byte-wide memory. In 'big endian' format, the most significant byte is stored in the first byte (lowest address). In 'little endian' ...
