Review of the book the Arduino controlled by eforth by dr
chen-hanson ting published in 2018

written by chen-hanson ting

Late Dr. ting was a chemist turned engineer. he earned a phd in
chemistry at the U of Chicago in 1965. taught chemistry in Taiwan
until 1975. became a firmware engineer until hI retirement in 2000.
he was a forth advocate for more than 50 years, especially a forth
called eforth that has been ported to many devices, including the
micro chip atmega 328 found on the arduino uno board.

I found this book while searching for forths for the arduino uno
boards. the source code and documentation for eforth is available
in a lot of places I will put a few links in the show notes.

I believe I mentioned this forth in an earlier hpr where I talked
about choosing a forth.

forth interest group

The book has 6 parts.

part 1 is dr tings musings on how he ended up creating 328eforth.

part 2 explains installing eforth.

the 3rd part begins exercising the arduino board using forth in
the interactive interpreter.

part 4 explains 328eforth implementation and design decisions.

part 5 is the full commented source code of 328eforth and, this is
the best part, dr tings explanation of what is going on in the
code broken down by functional sections. a gold mine of
information!

part 6 conclusions

The last part is his conclusions and examples to learn forth.

This is a great free software project. nothing is hidden. it is
accessible to anybody who would take the time to read and dig into
the code. its makes assembly language much less dark and
foreboding.

I'll finish by reading a couple of paragraphs from dr tings book

dr ting concludes:

People using computers are trained to be slaves. You are
taught to push certain buttons, and your are taught to push
certain keys. Then, you get employed to push buttons and keys
to work as slaves. Computers, programming languages, and
operating systems are made complicated to enslave people.

Computers are not complicated beyond
comprehension. Programming languages and operating systems do
not have to be complicated. If you get a sharp knife, you can
be the master of your destination. 328eforth is a sharp
knife. Go use it.

The hacker ethos.

The next podcast I produce will cover installing eforth on an
arduino board and solving that pesky loss of words between boots
problem.
