NXP mbed Design Challenge10Simon Ford | The mbed Challenge Is On!The mbed team is setting out to make rapid prototyping with microcontrollers a reality. Now it is your chance to get involved, develop something remarkable, and help move the industry forward. Are you up to the challenge? |
The Consummate Engineer12George Novacek | Good Old PALsMicrocontroller monitoring is essential to ensuring the reliability of a design. But watchdog timers don't always fit the bill. An alternative is a programmable array logic (PAL) arbitrator, which if used properly can significantly improve a system's fault-detection capability. |
16Riley Kotchorek Michael R. Smith Vahid Garousi | Mobile Application DevelopmentPart 1: Program a Sound-Monitoring PrototypeMobile medical devices are poised to change how healthcare professionals service their patients' needs. This series details how to develop a prototype Windows Mobile application for such a purpose. In this article, you learn about programming a sound-monitoring prototype used to identify medical issues related to sleep apnea. |

The Darker Side50Robert Lacoste Yannick Avelino | Parasitic ComponentsWhen Capacitors Behave Like InductorsEvery engineer understands the importance of capacitors. But what happens when a capacitor starts behaving like an inductor? The experiments presented in this article show that capacitors aren't always as simple as they seem.Download: Lacoste-245.zip |
From the Bench58Jeff Bachiochi | Encoder EssentialsHow to Close the Loop with HardwareComponent control is a key aspect of any successful robotics or mobile application. But a control system is ineffective without accurate, timely feedback. Enter the encoder, which can play a variety of important roles in a robotics application. This article details why closing the loop with feedback is an important part of the "control formula." |
Silicon Update66Tom Cantrell | What's My Line?Moving Toward a General-Purpose ChipProcessor, controller, DSP? Once the difference was clear, but over time it has blurred. Sure, there are still obvious differences at the extremes: the 'x86 in a PC is a processor, a PIC is a controller, and a SHARC is a DSP. But otherwise, the trend is toward general-purpose chips that cover all the bases. |
