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 ...

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 ...

Chris Edwards explains how interrupt handling is being offloaded from microcontrollers. For a number of reasons, including cost, embedded microprocessors have been required to take on tasks for which ...

In the interrupt method, the device that needs the microcontroller’s service notifies it by sending an interrupt signal. The microcontroller stops whatever task it is doing whenever it receives an ...

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 ...

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.

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 ...

Developing Internet-connected device applications is a daunting task for embedded-systems designers. Few have more than a limited knowledge of the Internet Protocol and the various related protocols ...

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 ...
