Silicon Labs recently announced its acquisition of of Micrium, an RTOS software supplier. The strategic acquisition it intended to strengthen Silicon Labs’s position in the IoT market.
The following statement from Daniel Cooley, Senior Vice President and General Manager of Silicon Labs’s IoT products, was presented in a release:
IoT products are increasingly defined by software. Explosive growth of memory/processor capabilities in low-end embedded products is driving a greater need for RTOS software in connected device applications… The acquisition of Micrium means that connected device makers will have easier access to a proven embedded RTOS geared toward multiprotocol silicon, software and solutions from Silicon Labs.
In celebration of Circuit Cellar’s 25th year of publishing electrical engineering articles, we’ll release a special edition magazine around the start of 2013. The issue’s theme will be the past, present, and future of embedded electronics. World-renowned engineers, innovators, academics, and corporate leaders will provide essays, interviews, and projects on embedded design-related topics such as mixed-signal designs, the future of 8-bit chips, rapid prototyping, FPGAs, graphical user interfaces, embedded security, and much more.
Here are some of the essay topics that will appear in the issue:
The history of Circuit Cellar — Steve Ciarcia (Founder, Circuit Cellar, Engineer)
In addition to the essays and interviews listed above, the issue will also include:
PROJECTS will be available via QR codes
INFOGRAPHICS depicting tech-related likes, dislikes, and ideas of hundreds of engineers.
And a few surprises!

About Circuit Cellar
Steve Ciarcia launched Circuit Cellar magazine in 1988. From its beginning as “Ciarcia’s Circuit Cellar,” a popular, long-running column in BYTE magazine, Ciarcia leveraged his engineering knowledge and passion for writing about it by launching his own publication. Since then, tens of thousands of readers around the world have come to regard Circuit Cellar as the #1 source for need-to-know information about embedded electronics, design, and programming.
Ready to start a low-power or energy-monitoring microcontroller-based design project? You’re in luck. We’re featuring eight award-winning, green energy-related designs that will help get your creative juices flowing.
The projects listed below placed at the top of Renesas’s RL78 Green Energy Challenge.
Electrostatic Cleaning Robot: Solar tracking mirrors, called heliostats, are an integral part of Concentrating Solar Power (CSP) plants. They must be kept clean to help maximize the production of steam, which generates power. Using an RL78, the innovative Electrostatic Cleaning Robot provides a reliable cleaning solution that’s powered entirely by photovoltaic cells. The robot traverses the surface of the mirror and uses a high voltage AC electric field to sweep away dust and debris.

Cloud Electrofusion Machine: Using approximately 400 times less energy than commercial electrofusion machines, the Cloud Electrofusion Machine is designed for welding 0.5″ to 2″ polyethylene fittings. The RL78-controlled machine is designed to read a barcode on the fitting which determines fusion parameters and traceability. Along with the barcode data, the system logs GPS location to an SD card, if present, and transmits the data for each fusion to a cloud database for tracking purposes and quality control.

The Sun Chaser: A GPS Reference Station: The Sun Chaser is a well-designed, solar-based energy harvesting system that automatically recalculates the direction of a solar panel to ensure it is always facing the sun. Mounted on a rotating disc, the solar panel’s orientation is calculated using the registered GPS position. With an external compass, the internal accelerometer, a DC motor and stepper motor, you can determine the solar panel’s exact position. The system uses the Renesas RDKRL78G13 evaluation board running the Micrium µC/OS-III real-time kernel.
Water Heater by Solar Concentration: This solar water heater is powered by the RL78 evaluation board and designed to deflect concentrated amounts of sunlight onto a water pipe for continual heating. The deflector, armed with a counterweight for easy tilting, automatically adjusts the angle of reflection for maximum solar energy using the lowest power consumption possible.

Air Quality Mapper: Want to make sure the air along your daily walking path is clean? The Air Quality Mapper is a portable device designed to track levels of CO2 and CO gasses for constructing “Smog Maps” to determine the healthiest routes. Constructed with an RDKRL78G13, the Mapper receives location data from its GPS module, takes readings of the CO2 and CO concentrations along a specific route and stores the data in an SD card. Using a PC, you can parse the SD card data, plot it, and upload it automatically to an online MySQL database that presents the data in a Google map.

Wireless Remote Solar-Powered “Meteo Sensor”: You can easily measure meteorological parameters with the “Meteo Sensor.” The RL78 MCU-based design takes cyclical measurements of temperature, humidity, atmospheric pressure, and supply voltage, and shares them using digital radio transceivers. Receivers are configured for listening of incoming data on the same radio channel. It simplifies the way weather data is gathered and eases construction of local measurement networks while being optimized for low energy usage and long battery life.

Portable Power Quality Meter: Monitoring electrical usage is becoming increasingly popular in modern homes. The Portable Power Quality Meter uses an RL78 MCU to read power factor, total harmonic distortion, line frequency, voltage, and electrical consumption information and stores the data for analysis.

High-Altitude Low-Cost Experimental Glider (HALO): The “HALO” experimental glider project consists of three main parts. A weather balloon is the carrier section. A glider (the payload of the balloon) is the return section. A ground base section is used for communication and display telemetry data (not part of the contest project). Using the REFLEX flight simulator for testing, the glider has its own micro-GPS receiver, sensors and low-power MCU unit. It can take off, climb to pre-programmed altitude and return to a given coordinate.
