TCP/IP in Embedded Systems

Transferring data between computers via TCP/IP extends beyond mainframes and desktops into the embedded world. Richard examines the layers of this protocol to see how data passes through the various systems.


Jim Butler


An Object-Oriented Network Protocol for Monitoring and Distributed Control

BACnet, unlike Ethernet or TCP/IP, focuses on the structure of the data communicated. Geared for industrial building systems, this standard offers functionality within a device via objects and services.

Getting Pumped

DC-to-DC Charge-Pump Converters

If you decide to use a switch-mode power supply in a design, you need to know about DC-to-DC converter theory. It helps you make the best design choices and to eliminate unnecessary EMI.

A Sweet Solution: Networking Embedded and Desktop PCs Using QNX

This month, Fred turns matchmaker. Teknor's VIPer and a desktop PC meet QNX and 10BaseT. It was love at first sight. Each machine's memory, drive, and port resources became part of the other. Oh! To find such a catch.

Unconventional Access

Sometimes you inherit a project and you can't get to the code. If that's your situation, then Jeff has a BUD for you. No, not the kind you drink. He offers a BASIC untokenizing device. Pop this one open, and pretty soon, you'll be in business.
