Why Buffer? Because buffers cut you some slack. Inevitably, in our recent series on microcontroller interrupts, the question of how to deal with actual serial data came up. In those examples, we were ...

A recent announcement from Micro Digital explained how the company's smx real-time operating system can do precise profiling of code operations. “… smx v4.1 solves this problem by using the clock ...

This article is part of the Ideas for Design Series: Vol. 3, No. 8. In many applications, accurately sensing the position of an electrically controlled mechanical device such as a motor is critical.

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 ...

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 ...

Just as you can often treat device registers as a memory-mapped struct, you can treat an interrupt vector as a memory-mapped array. In my last column, I suggested that you use casts sparingly and with ...
