Parker, I am very impressed by your ability to implement this unit with a single MCU. This is becoming the trend. MCUs with 32-bit processors and lots of supporting functionality (e.g., ADCs) on chip are making it much easier to implement designs quickly and more reliably. I wonder how much of this implementation is in the software as oppossed to discrete logic as in the past.
I am impressed too - especially by the thorough but easy to understand technical explanations provided to explain barcode scanner technology. Thanks for a very interesting article that just added to my understanding of this extremely utilized technology that is often taken for granted as well as the possibilities, something that I had not given much thought to before your very well-written article.
naperlou, I agree. The ability to package a complete system on a chip (SoC) is very impressive. With consumer electronic devices being small in size, microcontroller manufacturers are designing and packaging complete product designs on a piece of silicon. The Silicon Lab's Precision32 MCU is quite impressive because a complete barcode scanner is placed into a small iC package. This article is definitely worth sharing with my ITT Tech Students. Great article Parker!
As an industry, we now need to up our game and provide contractors with easier ways to properly identify and report counterfeit products and build collaboration between manufacturers, design engineers, industry organizations, and government.
The shift to aluminum is gaining momentum and the demand from automakers for aluminum is soaring, "expecting to reach one billion pounds this year, up from 200 million in 2012, and to grow by more than 30% annually through 2020."
