While the applications of LEDs are myriad, so too are the technical nuances of driving them efficiently, with well-controlled and evenly spread luminous intensity. To help you keep up with and understand the main differences in the many LED driver ICs now being introduced, we've developed this comparative table. Use it in conjunction with our two highly popular LED courses to succeed in your next LED-based design.

Designers are faced with a bewildering selection of MCUs upon which to base their next embedded system. This regularly updated comparative table of recently announced microcontrollers, along with the associated Fundamentals of MCUs course, will help make the selection process a little easier for the embattled engineer.

Is there a value for design engineers in product teardown analysis, a phenomenon that has proliferated in recent years but which offer typically outdated information while serving as a marketing tool in the hands of some OEMs, researchers, stock traders and publishing companies?

The 16-Gbyte version of Apple's iPhone 4 carries a bill of materials cost of $187.51, keeping with Apple's strategy of maintaining hefty profit margins on the popular smartphone, according to a teardown analysis conducted by market research firm iSuppli.

With the advent of wireless display technology, the modern "wireless home" can now include one less cable strung across the living room.

You could call the new Apple iPhone 4 an iPad Nano because it uses at least six chips from the popular Apple tablet, according to analysts from UBM TechInsights who have done a teardown of the new smartphone, revealing it uses a MEMS gyro from STMicroelectronics.

A team of experts reviews the evidence on Apple's A4 processor in an attempt to determine its origins and the influence of chip design houses recently acquired by Apple.

Join the EE Times Group as we unveil the results of our 15th annual survey of embedded designers in the US and Europe showing trends in software and hardware usage by vendor.

We'll demonstrate how using Wind River's Eclipse based visualization enhancements to Linux command line tools, like mpatrol and oprofile, can help give developers the needed advantage over using non-visual tools in the context of migrating existing code or developing new code for a multicore processor.

In this webinar, QNX Software Systems and Alcatel-Lucent examine how wireless Internet connectivity can be leveraged in embedded devices in markets as diverse as entertainment, health, enterprise, and automotive. Topics will include some of the challenges faced in building these devices, and what realistic solutions can be used to solve them.

This webinar provides background to the OpenGL ES 2.0 standard and opens up the graphics possibilities in embedded arena. The presenter will highlight benefits of having OpenGL ES 2.0 running on top of ARM Mali™ Graphics processors and the tools and resources available to enable developers and designers engineers to start developing for Mali GPUs.

Device software market leader, Wind River, will present a new solution for intelligent device testing that lets teams focus their efforts on what really needs testing.

This webinar includes a briefing from the Mentor Graphics OS engineering team, who will discuss the implementation of Nucleus OS and Linux on the Marvell Sheeva MV78200 Dual-core Embedded Processor.

In this course we will explore some of the fundamentals of ESL with particular emphasis on one of the most mature areas, namely high-level synthesis of the hardware portions of the system. While this area is maturing, different vendors have chosen different languages as their starting point and we will explore some of the tradeoffs that this makes.

This class covers sensorless vector control formulation for Brushless DC (BLDC) motors and its implementation techniques. The class starts with basic theory in terms of BLDC motor model, vector control principle, Clark & Park transformation, PWM modulation, flux observer, and speed and position estimation. Vector control based on sensor and its normal processing is briefly explained. Then the class focuses on processing for a sensorless vector control that does not use position or speed sensors. Specific implementation of the motor model based flux observer and overall sensorless vector control implementation strategy is described. Also, techniques for measuring currents via conventional sensors and using one-shunt reconstruction are explained. Finally, this class demonstrates the performance of sensorless vector control regarding speed regulation and CPU bandwidth usage.

Handheld mobile devices provide an ever richer range of applications and connectivity which, when combined with their limited computing resources and physical accessibility, implies a unique set of security issues. High-value services must operate alongside low-risk features and even user-downloaded applications. The complex mixture requires a rich OS environment which carries with it its own inherent vulnerabilities. This class outlines a security architecture tailored to provide the assurance required for high-value services while at the same time allowing the freedom needed for user-downloaded applications on the same device. Starting with the hardware components providing tamper-resistant monitoring and debug port protection, the class moves through tamper-evident software load and execution and through to system and user data protection. Finally, the class outlines the integration of these elements with software virtualization technology to provide assurance for high-value services. The virtualization solution runs a strictly contained and hardware access-restricted User OS. Alongside, but fully isolated from the User OS, virtualization allows a Trusted Execution Environment (TEE) to run, in which high-value services may operate out of reach of other features and applications.
