Getting Started with Xilinx EPLDs

The move from PLDs to EPLDs isn't a question of if, but when. In this article, Conrad shows you how to painlessly desgin with EPLDs. But, beware. If you're convinced, you might leave microcontrollers behind forever.

Getting Beyond the Box with Windows 95

Interfacing gadgets to the PC was easy until Windows 95.... Although user applications can't touch hardware directly, Craig shows us how to create helper programs that access any memory location or port.



David Prutchi

Designing Medical Electronic-Device Prototypes

Part 1: Design for Electrical Safety

Safety enters a new dimension when you're desgning electrical devices for medical purposes. David looks at electrical safety compliance standards, using sample circuits to illustrate how to "get safe".


Bob Perrin

High-Resolution ADCs

High-precision ADCs save corporations a lot of cost, but are far from a plug-and-play solution for design engineers. Bob goes over many of the gnats that determine which part is best for your situation.

In-Circuit Emulators

Part 3: Low-Cost ICE

Wrapping up this series of articles, the authors look in on a specific low-cost ICE -- Philips' PDS51 emulator. Hardware, software, and specific debugging techniques offer ways to get around tricky debug tracing.

Tuning Up: Part 2: Zerobeat Firmware

With integration it gets harder to figure out what a circuit is doing. This month, Ed takes a look inside Zerobeat's micro. He wants to know how the firmware is measuring audio frequency and converting it into a moving-dot LED display.

Maximizing X-10

Where others insist X-10 is unacceptable, Jeff relishes in finding solutions. No feedback from X-10. Well, not exactly true if you take the right steps. Too slow -- again, not if you're careful how you program. Curious how he does it? Check it out. He has some very practical solutions to X-10's lack of reliability.

Nonintrusive Current Monitoring: Part 2: Real-time Energy Profile

Last month, Jeff built toroids to check the current consumed in his home. This month, he puts them to work. Using a spreadsheet, he shares that information with us. Listen up if you also want to know where those kilowatts go.

Silicon Update

Oh Say Can USB?

Even if you have long hair, the worst snarls are frequently not on your head, but on your desk -- at least according to Tom. He applauds industry moves to sort and simplify his desktop wires. He's all for USB.
