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!
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.
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.
