Ultimate Guide to Switch Debounce (Part 8)

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...

Ultimate Guide to Switch Debounce (Part 7)

I think this is it! I honestly believe this is going to be the last installment in our switch bounce saga. This is where we finally get to consider software solutions to the switch bounce problem (along with a bunch of other topics, of course). Having said this, as usual there are no promises, because -- like you -- I have no idea what is to come until I've written it down.

Ultimate Guide to Switch Debounce (Part 6)

Way back in the mists of time, when I was bright-eyed and bushy-tailed, as I penned the first words in this quest to explore the topic of switch bounce and debounce, I actually thought it would take only one, perhaps two, columns. Sad to relate, as the days grew into weeks and the weeks grew into months, I grew into a much sadder and wiser man.

New DSP IP Makes Your Eyes Water

It seems that almost every day I hear about some cool and exciting techno-wonder originating with those clever guys and gals in Israel. For example, I currently have a WifiWall Traveler sitting in my shirt pocket. This little beauty, which came from the folks at, is small enough to fit in the palm of my hand (2.5" x 1.75" x 0.75"), yet it's awesome in its power.

Ultimate Guide to Switch Debounce (Part 4)

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 throw (SPST) toggle switch (see Part 3).

Could life evolve on ice worlds, ocean worlds, ocean worlds covered in ice, halo worlds that are tidally locked with their sun, and rogue worlds without a sun? If so, what sort of life might it be?...

I get pleasure from good quality things. Quality is a vague term, but, to me, it is some combination of good design for usability, functionality and aesthetics, along with reliability and durability. Some of these factors can be assessed very quickly; others take time. For ex...

[From the last episode: We looked at the complexities of cache in a multicore processor.] OK, time for a breather and for some review. We'€™ve taken quite the tour of computing, both in an IoT device (or even a laptop) and in the cloud. Here are some basic things we looked ...
