Simple Ethernet by Ken Merk

From: Circuit Cellar - October 2007 (Issue 207) - page 40

"You can use a picoFlash SBC with an Ethernet controller to send embedded Ethernet packets between master and slave nodes. The easy-to-use system make writing software and debugging a cinch."

"Forth as a Launch Vehicle" by Jack Woehr - May 1990

Contrary to popular belief, Forth is not just a programming language, it is also a programmable operating system. In recent years, such use has fallen below the event horizon as far as desktop computers are concerned. But in the relm of embedded control, Forth still serves as an amiable host to complied language programs.

...

If you are looking for a straightforward, inexpensive method of providing roll-your-own system services and powerful, on-board debugging capabilities for your compiled program, using a Forth system as your development platform may be just the answer you're looking for.

Designing Embedded Hardware, Second Edition - $45

Author: John Catsoulis

Publisher: O'Reilly

"Designing Embedded Hardware steers a course between those books dedicated to writing code for particular microprocessors, and those that stress the philosophy of embedded system design without providing any practical information. Loaded with real examples, this book also provides a roadmap to the pitfalls and traps to avoid. If you want to build your own embedded system, or tweak an existing one, this invaluable book gives you the understanding and practical skills you need."

Extensibility for Small Embedded Sytems - Brad Eckert

Using a dialect of Forth, Brad shows us how to combine run-time compilation and immediate execution of add-on firmware in order to make an embedded system extensible. New hardware introduces itself to the original firmware making the upgrade process much easier.

Building An Electrostatic and Magnetic Pulse Monitor - Richard W. Fergus

"Sferics is an abbreviation for "atmospheric electromagnetic radiation" and is the subject of a severe-weather-monitoring project that I’ve been involved with for nearly 40 years. The monitoring techniques have progressed from an omnidirectional pulse counter to detailed measurement of pulse shape and relative timing with the appropriate data-analysis procedures. The results from each monitoring system dictated the requirements for the next step. This project has been a tedious journey because each step generally required one or more yearly seasons to determine the relevant factors for the next step."
