MCU AND EMBEDDED SYSTEM TECHNOLOGIES

MCUs for Driverless Cars
By Jeff Child
Driverless cars are steadily advancing toward becoming a mainstream phenomenon. Building toward that goal, chip vendors are evolving their driver assistance technologies into complete driver replacement solutions. These solutions make use of powerful microcontroller solutions to analyze a car’s surroundings, process the information and employ control functionality to steer cars safely. Circuit Cellar Chief Editor Jeff Child examines the MCU technology and product trends that are key to driverless vehicle evolution.

Product Focus: Small and Tiny Embedded Boards
By Jeff Child
An amazing amount of computing functionality can be squeezed on to a small form factor board these days. These small—and even tiny—board-level products meet the needs of applications where extremely low SWaP (size, weight and power) beats all other demands. This Product Focus section updates readers on this technology trend and provides a product album of representative small and tiny embedded boards.

Portable Digital Synthesizer
By T.J. Hurd and Ben Roberge
Gone are the days when even a basic music synthesizer was a bulky system requiring highly specialized design knowledge. These two Cornell students developed a portable musical synthesizer using a Microchip PIC32 MCU. The portable system performs digital audio synthesis on the fly and produces sounds that range from simple sine waves to heavily modulated waveforms.

Displays for Embedded Systems
By Jeff Child
Thanks to advances in displays and innovations in graphics ICs, embedded systems can now routinely feature sophisticated graphical user interfaces. What used to require a dedicated board-level graphics/video board, now can be integrated into a chip or just a part of a chip. Circuit Cellar Chief Editor Jeff Child dives into the latest technology trends and product developments in displays for embedded systems.

Building a Twitter Emote Robot
By Ian Kranz, Nikhil Dhawan and Sofya Calvin
Social media is so pervasive these days that it’s hard to image life without it. But digital interactions can be isolating because the physical feedback component gets lost. Using PIC32 MCU technology, these three Cornell students built an emotionally expressive robot which physically reacts to tweets in a live setting. Users can tweet to the robot’s Twitter account and receive near instant feedback as the robot shares its feelings about the tweet via physical means such as sounds, facial expressions and more.

Understanding the Role of Inference Engines in AI
By Geoff Tate, Flex Logix
Artificial Intelligence offers huge benefits for embedded systems. But implementing AI well requires making smart technology choices, especially when it comes to selected a neural inferencing engine. In this article, Flex Logix CEO Geoff Tate explains what inferencing is, how it plays into AI and how embedded system designers can make sure they are using the right solution for their AI processing.


FUN WITH LIGHT AND HEAT

Watt’s Up with LEDs?
By Jeff Bachiochi
When Jeff puts his mind to a technology topic, he goes in deep. In this article, he explores all aspects of LED lighting—including the history, math, science and technology of LEDs. He discusses everything from temperature issues to powering LEDs. After purchasing some LEDs, Jeff embarks on a series of tests and shares his results and insights.

Automating the Art of Toast
By Michael Xiao and Katie Bradford
The emergence of culinary robotics and automation has already begun to revolutionize the way we prepare our meals. In this article, learn how these two Cornell undergraduates designed an advanced toaster that’s able to toast any pattern—image, text or even today’s weather—onto a piece of bread. The project makes use of Microchip’s MIC32 MCU and a Raspberry Pi Zero W board.

Build an RGB LED Controller
By Dirceu R. Rodrigues Jr.
There are a lot of fun and interesting things you can do with LEDs and different ways to control them. In this article, Dirceu describes an alternative approach to control RGB LEDs using the parallel FET dimming technique. He steps through his efforts to design and build an alternative lightning system based on power RGB LEDs. To control them he goes very old school and uses an 8-bit MCU and the BASIC programming language.


… AND MORE FROM OUR EXPERT COLUMNISTS

Energy Monitoring Part 3
By George Novacek
This is the final installment of George’s energy monitoring article series. He discussed the solar power supply in Part 1 and the utility power data acquisition in Part 2. In Part 3, he wraps up the series by looking at the remaining modules that comprise his home energy monitoring setup, including the sensors, the natural gas monitor and the real-time clock.

The Fundamentals of Fuseology
By Robert Lacoste
Just because an electronic device is simple you shouldn’t relegate it to an afterthought in your embedded system design. Such is the case with fuses. Robert explores the fundamentals of this seemingly simple device. In this article, he dives into the history, key specifications and technology of fuses. He also steps you through an experiment to analyze the performance of fuses and shares his results.

Bluetooth Mesh (Part 4)
By Bob Japenga
In this next part of his article series on Bluetooth mesh, Bob looks at how models are defined in the Bluetooth Mesh specification and how practical it is to use them. He looks at the models defined by the Bluetooth SIG and discusses creating your own models for Bluetooth Mesh.
