Microcontroller interrupts are one of the big tools in our embedded programming arsenal. They make the chip listen for particular events, and once detected they stop what they’re doing and run a ...

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 ...

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 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.

Until now we learned how to connect an LED as an output device, and a button switch as an input device. Besides, we already studied the basic facts about AVR fuses, and the coding procedure to a ...

Welcome to The Zephyr* RTOS with the Intel® Quark™ microcontroller D2000! Intel is now building embedded microcontrollers. They’ve taken the Pentium® processor and taken it down to microcontroller ...

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 ...
