Alberto Ricci Bitti

PDF HTML, HTML, HTML X-Y Graphing Data Logger

With more data than he can handle (and always in some inconvenient place), Alberto constructed a powerful, handheld, programmable data logger from his Casio pocket calculator. And as a reward, Design98 judges made it their "first PIC."

Glenn Parker

Time-Domain Filter Simulations Using C++

When you have to work with filters -- and what hardware engineer doesn't at some point? -- you'll want to try out Glenn's complete C++ filter class. He's ready to prove how easy it is to integrate this class into embedded apps.

Gerard Fonte

Breaking Nyquist

Post-Sampling Antialiasing

You'd think someone would have figured it out by now: you can't get away with challenging an engineer. Gerard is set to disprove the common belief that DSP can't identify aliased signals. According to him, you can get around Nyquist!

Note: Further discussion by Darrell Hambley and Paddy McKee in INK 101 Reader I/O.


Tom Napier

HTML Digital Frequency Synthesis

Some of the best inventions happen by accident. At least, that's how it is with Tom's project. While merely intending to beef up his NCO generator, Tom found a way to embed a low-cost accurate tunable sine-wave generator, using just a PIC.

Jim Brady

PDF, PDF HTML, HTML, HTML Networking with DeviceNet

Part 2: A Weather-Station Application

Think programming a DeviceNet interface in C++ is tough? Jim disagrees. With its excellent response times and adequate program size, Jim gets the same excitement writing code for a fast 32-bit CPU as he got from his '67 Camaro.

Ingo Cyliax

Real-Time PC

The Need for Speed, RTOS and PC/104

When it comes to speed, more is better -- except when you're considering price. Ingo's ideas about speeding up transfers in and out of PC/104-based DES engines give us a less expensive product with the same performance.

Fred Eady

Applied PCs

RF and Micros, Part 2: A Low-Power System

Fred's taken to the airwaves again. using a DVP transmitter/receiver pair, he shows us how RF can be employed where wires previously dominated -- with the amazing potential to touch 256 printers over a single RF link.


David Tweed


Digital Processing in an Analog World, Part 1: Basic Issues

Conversion is always a hot topic, but David's not talking religion here. Instead, he wants to fill us in on the basics of A/D and D/A conversion, so that we'll be ready to delve into the deeper issues in the coming months.


Jeff Bachiochi

From the Bench

MIDI, Part 1: It Ain't Just for Music Any More

Ever think of turning your PC into a recording studio? This month, Jeff starts a project that lets you identify the state of outputs through the sound you create using the MIDI sequencer program.



Tom Cantrell

HTML, HTML Silicon Update

MegaMicro Card

In the world of data flash cards, Tom compares MultiMedia Card to CompactFlash and Nexcom. His result bodes well for the smaller, faster, and more versatile MMC in a variety of handheld products.
