Stephen Manley

Palm OS Data Acquisition

It's never been so easy and inexpensive to build data-acquisition and data-monitoring applications. For instance, Stephen recently developed a set of digital gauges for his car, and all it took was a Palm, an ATmega163, and a little forethought.



Terry Fleischman

Speed and Location Data Acquisition

As co-chair of the High Mileage Vehicle Challenge, which is a contest amongst designers to get the most mileage from a gas-powered vehicle, Terry was looking for ways to enhance the contest. He and his engineering students volunteered to create a way to remotely monitor the speed and location of multiple vehicles. The project turned out to be educational and fun, but don't just take their word for it, try it yourself.



Keith Brown

LED-Based Color Clock

Tell Time Anytime

Keith's LED-based "color clock" may not look like a conventional clock, but it works just as well. Read closely as he explains how he came to create an entirely new way of displaying and reading the time of day.



Olaf Pfeiffer

HTML Embedded Networking with MicroMessaging

Mixing technologies can get messy, so if you're interested in providing a common network protocol for applications incorporating different networks, MicroMessaging is the solution for you. Allow Olaf to walk you through the MicroMessaging basics, and you'll surely find it easier to develop your next embedded-networking project.



Dick Cappels

Minimum Mass Waveform Capture

In this article, Dick shows you how to capture repetitive waveforms at 1 Msps using an AT90S2313 microcontroller's on-chip PWM and comparator.



Brian Millier

Serial Sidekick

Brian built the perfect device for troubleshooting the serial data communications methods he uses. He calls his bench-side assistant the Serial Sidekick. The small, stand-alone device can graphically represent up to four signal lines and has miniterminal capability.

Simple Data Display, Driving LCDs with Microchip and Atmel Micros

Thinking about incorporating an LCD in your next design? It isn't too difficult, especially if all you're looking to do is display your data as a set of numeric digits. Follow along as Fred shows you how Microchip and Atmel can help you drive a simple data display.

Designing with RGB LEDs

With an 8-bit microcontroller driving an inexpensive RGB LED, you can bring nearly any color of the rainbow to your next project. Jeff chose a PIC12F675 for his innovative design. In this article, he explains everything, including the simple code you'll need to get started.



Ed Nisley

Above the Ground Plane

Modulation and Demodulation

Our understanding of radio technology has come a long way since Hertz's nineteenth-century experimentations. In this column, Ed shows you what a simple AM modulator does to a carrier and an audio tone. In addition, he describes how you can demodulate the signal to recover the audio.



Tom Cantrell

Silicon Update

In ARM's Way

You cannot always measure a tech company's strength by what you read in the financial pages of a newspaper. Sometimes you have to dig deeper. Fortunately, you can turn to Tom when you're looking for the scoop on companies working in the world of silicon chips. In this column, he cuts through the news stories, press releases, and rumors to set the record straight regarding ARM's past, present, and future.
