Editor's Note

Bernard Cole Bernard Cole
Site Editor

The November issue of Embedded Systems Design Magazine is now available online. The new issue includes:

Making late-night debugging an exception rather than the norm
Using Agile's Scrum in embedded software development
The semiconductor revolution ,” by Jack Ganssle
Firmware forensics,” by Michael Barr
Android at ESC and IDF ” by Chris Ciufo

To complement the coverage of Agile software development in this month's issue, read “Agile Adventures in an Embedded World ,” by Mike Hogg, who will be contributing columns on this topic regularly to Embedded.com.

Late breaking news out of last week's ARM Developer Conference: ARM's new 64-bit CPU , AMCC's 64-bit ARM server chip , HP's ARM server prototype , TI's $5 Sitara ARM processors, and the $89 Beaglebone Sitara development board.

In addition to my Editor's Top Pick – “Using hardware to save energy in MCU-based sensing apps,” by Energy Micro's Rasmus Christian Larson – other design article topics on Embedded.com this week include: noise issues in touchscreens, implementing high speed USB, and hunting noise in wireless apps. Also, I have written a new column on my days working at Caltech, titled: “The 4004, nanometer CMOS VLSI and MEMS logic.”

Design How Tos

Using hardware to save energy in MCU-based sensing applications

Here is how to offset the energy cost of implementing functions in software by extracting relatively complex functions or algorithms and embedding them in hardware designed for low energy consumption.

Making late-night debugging an exception rather than the norm

Static analysis finds the bugs, even if you're working under an Agile development process. Here's when and where to use static analysis.

Using Agile's Scrum in embedded software development

Keeping the team focused and organized is what Scrum can do for your embedded systems project.

Noise wars: Projected capacitance strikes back against internal noise

Understand how charger and display noise impact touchscreens, and what can be done about it

Hunting noise sources in wireless embedded systems

In this article, we will explore tips and techniques for hunting noise sources using a new type of instrument called the mixed domain oscilloscope, or MDO.

A charging approach to increase runtime in portable applications

Applications such as LTE and smartphones place complex demands on the battery and power subsystem; here's one approach to meeting that demand

Simple ways to manage different clock frequencies of audio codecs

By proper reconfiguration of the digital filters, sample rate conversion and flexible clock frequency choices, a wide range of audio-video applications can be supported with modern audio codecs.

Implementing high Speed USB functionality with FPGA- and ASIC-based designs

A wide range of FPGA-based applications exist that can benefit greatly from the addition of a high speed USB interface…

Back EMF method detects stepper motor stall: Pt. 1—The basics

Technique takes advantage of constant motor parameters and overcomes limitations of traditional stall detection methods of current and duty-cycle sensing.
