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 ...

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 ...

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 ...

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 ...

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 ...
