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!
There are drivers everywhere who turn on their headlights or windshield wipers with no awareness of the development effort behind a switch. Yet from freezing winter to sweltering summer, on dull rainy days and in bright sunshine, switches are expected to function consistently for the lifetime of a car.
The standards electrical machines and components are required to meet in the food processing industry are far more stringent than those in traditional plant construction. For specialized production environments such as these, components must not only resist thermal and physical stresses, but they must also be resistant to the chemicals used to sterilize equipment.
The word “smart” is becoming the dumbest word around. It has been applied to almost every device and system in our homes. In addition to smartphones and smart meters, we now hear about smart clothing and smart shoes, smart lights, smart homes, smart buildings, and every trendy city today has its smart city project. Just because it has a computer inside and is connected to the Web, does not mean it is smart.
Was Steve Job’s signature outfit of a black turtleneck, jeans, and sneakers the secret behind his success? Maybe, or maybe not, but it was likely an indication of a decision-making philosophy that enabled him to become one of the most successful innovators of all time.
