In designing µC-based systems, you often face a situation in which the µC has to respond to an external event happening at an uncertain moment in time. One example is receiving an echo from an object ...

Welcome to part three of “Interrupts: The Good, the Bad, and the Ugly”. We’ve already professed our love for interrupts, showing how they are useful for solving multiple common microcontroller tasks ...

Edge-triggered interrupts are useful in microcontroller (MCU) applications for processing asynchronous events like switch closures, level transitions, and pulses. However, low-cost MCUs offer limited ...

The need for timing in embedded programming often exceeds the small number of available hardware timers in microcontrollers. For example, the Microchip PIC16F84A has one timer, but you can create as ...

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 ...

Microcontroller units (MCUs) are single-chip computers optimized for performing embedded computing tasks like controlling a ...

As portable systems become increasingly power-conscious, the need for smart power management becomes equally important. Besides the main processor, an auxiliary Microcontroller Unit (MCU) often ...

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 ...

April 17, 2008 – National Instruments and ARM today announced the NI LabVIEW Embedded Module for ARM Microcontrollers, an extension of the LabVIEW graphical system design platform that directly ...
