The Solution's in the CAN -- Part 1

Industrial-class, Small-area Networks

In the first of a two-part series on CAN, Brad looks specifically at the CAN protocol and how it and its existing hardware implementations meet the requirements of a small area network.

The RDS Prospector

Read Your Radio!

RDS enables a radio to display messages recovered from the inaudible 57-kHz band of the FM signal. Chris introduces us to an inexpensive decoder which displays text and works with an existing FM tuner.

Siemens ESCC2 UART

Making a High-speed Audio Link Sing

Not at the speed of light, but almost the speed of sound, the ESCC2 sings. This UART offers the harmony of high-speed asynchronous transmission through hardware interface, initialization, and software algorithms.


Robert Priestley

Low-cost PC-based Universal 68HC705 Development System

Faced with a mammoth project, Robert realized he'd never get done unless traditional burn methods were replaced with something less tedious. His solution: a 68HC705 development system.

Time in a Can: Just Add 1 Bit of I/O

It's almost time to open the cooler and chug back those cans. This Bud's real cool. It offers a combination of elapsed time, enabled counts, ID serial number, and NVRAM.

Silicon Update

EPAC Epoch

Cursed by analog? Latch onto this new electronically programmable analog circuit. In Tom's opinion, this circuit marks the beginning of a new trend in computing analog relations.
