Max Maxfield Articles Featuring LogiSwitch


NEW


Max Maxfield, (a.k.a. Clive Maxfield, a.k.a. Max the Magnificent), author of numerous books on embedded computer technology and revered throughout the electronics industry as a leading technical guru, has gifted our company with a number of technical articles and YouTube tutorials featuring LogiSwitch products. 

Well-known throughout the embedded, electronics, semiconductor, and EDA industries, Max has presented papers at numerous technical conferences around the world, including North and South America, Europe, India, China, Korea, and Taiwan. He has given keynote presentations at the PCB West conference in the USA and the FPGA Forum in Norway. He's also been invited to give guest lectures at several universities in the US and at Oslo University in Norway. In 2001, Max "shared the stage" at a conference in Hawaii with former Speaker of the House, "Newt" Gingrich.

Max is the author of a number of books, including Designus Maximus Unleashed (banned in Alabama), Bebop to the Boolean Boogie (An Unconventional Guide to Electronics), EDA: Where Electronics Begins, FPGAs: Instant Access, and How Computers Do Math.

It is our honor to provide a list of links to Max's published articles and YouTube videos featuring LogiSwitch products:


1. SAY HELLO TO THE LOGISWITCH WORKBENCH

Published on the Altium PCB Software website https://www.altium.com December 27, 2019.

Max deftly points out how the LogiSwitch WorkBench helps to remove clutter from, and provide three times the workspace to, your Arduino prototype projects.

2. ARDUINO UNO DRIVING 45 LEDs ON 3 BREADBOARDS USING THE LOGISWITCH WORKBENCH

Clean YouTube Demo of 45 LEDs driven by an Arduino Uno with no jumper wires using the LogiSwitch WorkBench.

3. QUIT BOUNCING AROUND

Published on the Altium PCB Software website https://www.altium.com January 3, 2020.

This article is an excellent short tutorial on the phenomenon of switch bounce and the hardware approach to debouncing it. Both families of LogiSwitch debouncer ICs are explained in the truly excellent detail only Max can provide: the higher-tech LS1xx Series with its powerful ultra-high-speed handshake protocol, and the lower-tech glitchproof LSxx Series. This article also starts out with an introduction to LogiSwitch's new Arduino Uno WorkBench prototyping tool.

4.  LOGISWITCH ARDUINO UNO WORKBENCH PROTO-EXTENDER KIT.  

Published on the Clive Maxfield High-Tech Consulting website.

The Arduino Uno Proto-Extender Workbench Kits from LogiSwitch > LogiSwitch Store,  allow users to breakout all of the Arduino's pins (power, ground, and analog/digital input/outputs) three times (to three different sides), thereby allowing all of the pins to be made available to three different breadboards. This side-by-side demo shows a standalone Arduino Uno driving three breadboards using flying leads (right), as compared to the same design implemented using a LogiSwitch Workbench Kit (left) Also check out his Cool Beans Blog that details a real-world usage scenario on one of his own projects  > READ IT HERE

5. HURRAY FOR THE COOL BEANS BLOG YOUTUBE CHANNEL!  CLIVE MAXFIELD

Published on the Clive Maxfield High-Tech Consulting website. 

This article starts out demonstrating Max's ideas for creative effects for turning on and off simple unicolor LEDs. Further down in the page, he demonstrates a 45-LED demo, first using jumper wires direct to the three breadboards from the Arduino Uno, then showing the same circuit construction using the LogiSwitch 3-Bank WorkBench for comparison.

6. ULTIMATE GUIDE TO SWITCH DEBOUNCE 

This series of articles published on the Electronic Engineering Journal website provides the most detailed treatise on the switch bounce phenomenon published anywhere. In Max's words: "In Part 1 of this miniseries, we introduced the concept of switch bounce; that is, when we open (deactivate) or close (activate) a switch, it may make multiple transitions before eventually settling in its new state (see also my Switch Types and Switch Terminology columns). We also noted that this occurs in toggle switches, rocker switches, pushbutton switches, and so-forth — pretty much everything apart from the switches most of us never use anyway, like mercury tilt switches, for example.  > Ultimate Guide Part ONE


In Part 2, we took a deeper dive into the bouncing associated with single pole, single throw (SPST) and single pole, double throw (SPDT) toggle switches, including some empirical data as to how long switch bounce might persist, how wide the individual bounce pulses might be, and how many bounces we might expect to see. Also, we introduced the point that whatever technique we use to address switch bounce – pre-processing the signal in hardware or post-processing it in software – it’s important that the technique is not fooled by the occasional noise “glitch” or “spike” caused by crosstalk, EMI, (electromagnetic interference), RFI (radio frequency interference), or ESD (electrostatic discharge).  > Ultimate Guide > Part TWO 


Now, in Part 3, we have arrived at the point where the “rubber meets the road,” metaphorically speaking. This is where we start to consider various solutions to our bouncing switches."  > Ultimate Guide Part THREE


Part 4 outlines some hardware debouncing solutions using random logic devices. In this part of the series he demonstrates the obvious lack of ability of a monostable multivibrator (one shot) to perform the task of debouncing without some extraneous support logic devices . > Ultimate Guide Part FOUR


Part 5 is coming soon...


7. MAX'S HOT BEANS by Max the Magnificent
