TECHNOLOGY FOR SECURITY, SENSORS & THE IoT
Security Solutions for IoT
By Jeff Child
In this IoT era of connected devices, microcontrollers have begun taking on new roles and gaining new capabilities revolving around embedded security. MCUs are embedding ever-more sophisticated security features into their devices-both on their own and via partnerships with security specialists. Here, Circuit Cellar’s Editor-in-Chief, Jeff Child, looks at the latest technology and trends in MCU security.

PC-BASED SOLUTIONS FOR EMBEDDED SYSTEMS
Mini-ITX, Pico-ITX and Nano-ITX Boards
By Jeff Child
Products based on the various small-sized versions of the ITX form factor—Mini-ITX, Pico-ITX and Nano—ITX-provide system developers with complete PC-functionality and advanced graphics. Circuit Cellar Chief Editor Jeff Child explores the latest technology trends and product developments in these three ITX architectures.
Using Small PCs in New Ways
By Wolfgang Matthes
Even simple MCU-based projects often require some sort of front panel interface. Traditionally such systems had to rely on LEDs and switches for such simple interfaces. These days however, you can buy small, inexpensive computing devices such as mini-PCs and notebook computers and adapt them to fill those interfacing roles. In this article, Wolfgang steps you through the options and issues involved in connecting such PC-based devices to an MCU-based environment. FOCUS ON MICROCONTROLLERS
Guitar Game Uses PIC32 MCU
By Brian Dempsey, Katarina Martucci and Liam Patterson
Guitar Hero has been an extremely popular game for decades. Many college kids today who played it when they were kids still enjoy playing it today. These three Cornell students are just such fans. Learn how they used Microchip’s microcontroller and 12-bit DAC to craft their own version that lets them play any song they wish by using MIDI files.
Offloading Intelligence
By Jeff Bachiochi
While some embedded systems do just fine with a single microcontroller, there are situations when offloading some processing into a second processing unit, such as a second MCU, offers a lot of advantages. In this article, Jeff explores this question in the context of a robotic system project that uses Arduino and an external motor driver.
Building a Portable Game Console
By Juan Joel Albrecht and Leandro Dorta Duque
32-bit MCUs can do so much these days—even providing all the needed control functionality for a gaming console. Along just those lines, learn how these three Cornell students built a portable game console that combines a Microchip PIC32 MCU embedded in a custom-designed 3D-printed case, printed circuit board and in-house gameplay graphics. The device includes a 320 x 240 TFT color display.
… AND MORE FROM OUR EXPERT COLUMNISTS
Variable Frequency Drive Part 2
By Brian Millier
In Part 1 Brian started to describe the process he used to convert a 3-phase motor and OEM Variable Frequency Drive (VFD) controller—salvaged from his defunct clothes washer—into a variable speed drive for his bandsaw. In this article, he completes the discussion this tim,e covering the Cypress Semi PSoC5LP SoC he used, the software design and more.
Semiconductor Fundamentals Part 1
By George Novacek
Embedded systems—or even modern electronics in general—couldn’t exist without semiconductor technology. In this new article series, George delves into the fundamentals of semiconductors. In Part 1 George examines the math, chemistry and materials science that are fundamental to semiconductors with a look at the basic structures that make them work.
