How to enforce coding standards automatically
Difficulties constructing memory-mapped objects
Editor's Note
The embedded market sector this week seems to be ignoring divergent economic reports ( one optimistic and one pessimistic) and is forging ahead with products and specs designed to produce long-term positive results.
Among many news stories reflecting an optimistic outlook in the industry: Qualcomm has a quadcore processor and 28 nm process in the works, C*Core has a new Power CPU family, HiSilicon extends its ARM CPU licenses for nextgen wireless, and NI has updated Labview . In addition, progress has been made on a number of new specs: a new embedded browser benchmark , an API for multicore task management, the Smart Energy 2.0 Profile , and a new wireless Zigbee gateway spec .
If you are thrown off balance by market uncertainties, read “ Assume nothing ” , by Jack Ganssle. While he focuses on the importance of this attitude in embedded systems development, I found it a good guide to follow when trying to understand market behavior as well.
Two blogs in the Chips In Space series are especially interesting this week: “The importance & challenges of collaboration” and “The building of an amateur satellite ” by Microchip engineer Steve Bible on building the electronics for OSCAR (Orbiting Satellite Carrying Amateur Radio). I also recommend “ Making capacitive touch sensors water tolerant,” a Product How-To article by Mark Lee and “ Open Embedded: An alternative way to build embedded Linux distributions,” by Nick Lethaby and Denys Dmytriyenko.

Open Embedded: An alternative way to build embedded Linux distributions
Nick Lethaby and Denys Dmytriyenko of Texas Instruments provide an overview of the key elements of the Open Embedded Linux (OE) build environment and show how to use them to build and customize Linux distributions.
Migrating from proprietary to Linux (Open) development platforms
Linux specialist Rajaram Regupathy provides some tips on making the transition from a design based on a proprietary RTOS to one that makes use of the Linux (Open) standard.
Making capacitive touch sensors water tolerant
In this Product How-To article, Mark Lee of Cypress uses the company's CY8C21434 PSoC to explain the methods by which to integrate water tolerant capacitive sensors into consumer white goods where operation in wet environments is important.
Haptics technology: picking up good vibrations
Understand the existing and new techniques for implementing this motion-transducer function
Touch-screen technologies enable greater user/device interaction
Understand the workings of capacitive- and resistive-screen sensing, as well as the role of haptics
Capacitors can reduce size and improve efficiency
of cellular handset antennas
Applying thin-film technology to the manufacture of capacitors has enabled the development of components where both electrical and physical properties can be tightly controlled. These devices can be used to improve the efficiency of antennas used in mobile handsets.
Ultra-low power microcontrollers for compact wireless devices
This paper describes design strategies for ultra-low power microcontrollers for use in various existing and emerging wireless applications. Emphasis is placed on practical techniques to reduce both active and standby mode power. Design examples draw from experience with the ARM Cortex-M3 core.
Network test specs promote multi-vendor interoperability in the lab
Here is an overview of the first technical specifications developed by the Network Test Automation Forum to automate multi-vendor network test automation in the lab. The NTAF's simplification of lab automation efforts reduces time, complexity and cost of product test cycles.
Spread-spectrum clocking reduces EMI in embedded systems
PCI Express technology incorporates the use of spread-spectrum clocking to reduce EMI.
Managing signal integrity in tomorrow's high-speed flash-memory-system designs
Next-generation flash-memory technology will tout data-transfer rates as much as 10 times faster than currently available. However, increasing distortions in the data-carrying digital signals can cause data-transfer failures, complicating the management of signal integrity. Proper design strategies can help you deliver reliable, high-performance products.
Optimizing Power Line Communication for Distance, Lowest Packet Error Rates, Cost and Reliability
Recent advancements in technology, increasing growth in machine-to-machine connectivity, and the need for better resource management, are giving narrowband power line communications the attention it deserves as the most universally-available network medium.
Want to go Green? Reuse Powerline infrastructure and get there fast
If you are an engineer who cares about, or are working on, three of the most important Green technologies of our lifetime – Smart Grid, Solar, and LED Lighting – the ability to reuse the existing Powerline communications (PLC) infrastructure is an essential element for adding intelligence to applications based on these technologies.
