A Reliable Network for Embedded Systems

Getting on Track

Getting a low-cost and reliable embedded network on track can be quite a chore. Val and Gary put together a system of network nodes that is not only on track, but on the track -- in a high-performance racecar! Let's take a ride with LogNet.

The Shocking Truth About EMC

Part 2: Practical Application

Having covered the principles of EMC in Part 1, this month George sets out to show us how to keep everything in mind when designing electronic equipment. If you design electronic equipment, here's a handy ounce of prevention.

Russell Chadwick

Weather Data

Getting More Than One Wire's Worth

Russell and William rolled a weather station from Dallas and a Motorola 6808-based electronic interface display unit into an award-winning project in last year's design contest. And now, here's an inside look at how the project came together.


Robert Kondner

Buying Power

A Low-Cost Power Supply

If you've ever designed a small embedded system, only to find that the power supply costs more than the remaining components, you might want to take a closer look at Bob's project and consider rolling your own power supply.

Part 3: System-on-a-Chip Design

Now that the xr16 RISC processor is complete, it's time to tie everything together and wrap up this series. In this final part, Jan designs a demo system that includes an on-chip bus, memory controller, video controller, and peripherals.

Real-Time PC

Real-Time Executive for Multiprocessor Systems, Part 1: Introduction to RTEMS

Ingo sets out to explain how the RTEMS open-source licensed real-time kernel has evolved from its days at U.S. Missile Command. You just might consider using the current C version to launch your next application.

Under the Covers, Part 2: Applications via NT Embedded 4.0

If last month's introduction to Windows NT Embedded 4.0 got you wondering what kind of applications are possible, you're not the only one. Fred took the advice of some readers and considered Internet device control via emWare.


Joe DiBartolomeo

PDF MicroSeries

Op-Amp Specification, Part 2: Getting Some Input

In Part 2 of this MicroSeries, Joe discusses specifications for input offset currents and voltages, as well as input bias current. If low-frequency and precision applications are your thing, you won't want to miss this.


Mike Baptiste

Embedded Living

HCS = Heating Control System?

It may be Spring now, but one cold snowy day back in January, Mike got to pondering about his new HVAC system and how to tie it into his home-control system. Soon, he had the "H", "V", and "AC" singing in harmony with his HCS.

Digital and Analog Output Control, Taking Route X-10

Call it quirky, call it tempermental, call it mysterious, but you certainly can't call X-10 useless. Jeff's project sheds some light on controlling outputs via X-10.



Tom Cantrell

Silicon Update

On the Road Again, Part 1: Going Places with Silicon

This month, Tom combines two interests and taks an under-the-hood look at chips that reside under the hood. Peel back the chrome and leather and you'll see how "smart" today's cars really are.

PDF HTML Monitoring Your Micro

If you're going to keep your system running at its peak performance, it helps to be able to monitor the microprocessor. Most processors use counters to measure performance, but Daniel and Jim have a better way of gathering and analyzing performance data.

Robbert Maris

PDF HTML The Ultimate 16-bit Microcontroller

Memory organization, often ignored by chip vendors, significantly affects code density and speed. This is especially important in applications that involve user interface or extensive communications. Robbert outlines a solution that may reduce controller diversity in companies, hence reducing your tool investment.

Note: Additional comments about M16C from Ali Akrouf in INK #122 Reader I/O.
