They taught me a lot of things at university. Unfortunately, they neglected to mention the topic of switch bounce. If you are a practicing engineer working with electronic systems, you will almost certainly have run into this problem. If you are new to the field, you can be assured that the delights of switch bounce…

Movie history is replete with heroes and villains that refuse to die, despite grievous bodily harm. Here are a few quotes from various movies to help you remember these characters: “How many times do I have to kill you, boy?” – Jafar to Aladdin, Aladdin, 1992 “Why can’t you just die?” – Two-Face to Batman,…

What are the new programming assistants good for? For this practical report, Googles Bard is let loose on microcontrollers and has to show what it can do.

Previously, as they used to say at the start of a new episode in a TV series, we discussed the history behind the use of hardware vs. software to debounce our switches. We also perused and pondered the idea of using an RC network followed by a Schmitt trigger to debounce a single pole, single…

First reported in the 1940s, Metal Whiskers (MW) are spider-web-thin conductive filaments that sprout (most often) from tin, zinc, and cadmium metal...

Embedded systems engineering is fascinating to me because it is a field that is constantly changing and evolving. The dynamic nature of the field is taking place at an ever-accelerating rate, which means it keeps the practitioners on their toes to constantly learn, adapt and innovate. If a team or individual wants to be successful, they can’t be complacent but need to be continually honing their skill set. In today’s post, I’ll share several tips for how engineers can hone their skills an...

by Max Maxfield Are you familiar with the Tracealyzer and DevAlert tools from Percepio? How about the Luos distributed (not exactly an) operating system from Luos? I don’t know about you, but for me, the past few days have been jam-packed with my learning all sorts of exciting nuggets of knowledge and tidbits of trivia pertaining to the implementing, monitoring, and debugging of embedded systems using these little scamps. I’m not too sure where to commence, so let’s al...

Robust Software Design Necessary for Multithreaded Software Visual Trace Diagnostics Can Assist in Design Verification Västerås, Sweden, 4 May 2021   * * *   Percepio ® CEO Dr. Johan Kraft will present a selection of best practices in multithreaded embedded software design at the upcoming Embedded Online Conference, 17–20 May. Dr. Kraft will also discuss the concept of visual trace diagnostics and demonstrate how it can be used to analyze multithreaded software design in order to imp...

by Max Maxfield I can’t believe it; we’ve finally arrived at the ultimate part of what started out as a mini-series and ended up being a mega-epic. In a moment, we’re going to consider FPGA (hardware) and MCU (software) solutions to the switch bounce problem, but first… Just in case you arrived late to the party, in Part 1 we introduced the concept of switch bounce; in Part 2 we delved deeper into the bouncing associated with SPST and SPDT switches; in Part 3, Part 4...
