The Consummate Engineer52George Novacek | Environmental Stress ScreeningEnvironmental stress screening (ESS) takes time, resources, and equipment. But the advantages -- low field returns, design robustness, and component quality tracking -- are well worth it. |
Embedded in Thin Slices56Bob Japenga | Getting Started with Embedded LinuxPart 1: When to Choose Linux for Your Embedded DesignThis three-part series introduces the topic of embedded Linux. Why should you choose Linux? To begin with, many of the features, devices, and functionality you desire are already built into the operating system. Read on to find out more. |
From the Bench60Jeff Bachiochi | Get Your Head Out of the CloudAn API for Communication with a Wi-Fi ThermostatThe Utility Smart Network Access Port (USNAP) interface, which connects products into home networks, is gaining footing in the marketplace. Here you learn how to build applications to communicate with a Wi-Fi USNAP thermostat using an application programming interface (API).Download: Bachiochi-255.zip |
The Darker Side66Robert Lacoste | Line-Coding TechniquesThe nonreturn-to-zero (NRZ) method is a binary code in which ones are generally represented with a positive voltage and zeros are generally represented by a negative voltage leaving no null condition. This article details the NRZ method and other line-coding techniques -- NRZI, Manchester, Miller, AMO, MLT3, and 4B5B -- that can be used in wireless and wired protocols.Download: Lacoste-255.zip |
