Forth in Your Shirt Pocket: AmForth on an Arduino Uno -
Bill and Michael Ragsdale
Bill and Michael will present AmForth
running on an Arduino Uno with two applications: a Morse Code keyer and a GPS
Puzzle Box. He'll briefly introduce Forth for folks who have had little or no
exposure to the language and tell you how to get started with Forth on the
Arduino.

Introductions, announcements, and discussion - All
assembled
Everyone introduced themselves and remembered when they first
heard about Forth. |

SwiftX on an Arduino Uno - Leon Wagner
Leon
will demonstrate the SwiftX Integrated Development Environment for the Atmel
AVR microcontrollers on an Arduino UNO board. His discussion will include
details about the implementation strategy the Forth on the AVR.
- SwiftX AVR for
the Arduino Prototyping Platform paper and source code for the demo - 497
Kb zip file
- The app note SwiftX-Arduino.pdf discusses the SwiftX-AVR
implementation specific to the Arduino Uno and Diecimila boards and presents a
simple application for those boards. The subdirectory 'distress' contains the
source code for the sample application.
- Pololu USB AVR
Programmer - $20
- Replacement
ATMEGA328P-PU chips from Mouser
-
"If you want to try it out, the
SwiftX
evaluation version is free."
-
"Note that the installer for SwiftX-AVR gives you everything
you need. It has its own copy of AVRDUDE built in (I built it in the MinGW
environment so it doesn't need a bunch of DLLs) and also includes the drivers
for the Uno, the FTDI chip, and that nice Pololu programmer. You do not need to
go out and gather up a long list of stuff; it should all be here."
-
"You can easily modify the little FLASH.BAT script in the
project directory to work with the ISP programmer of your choice. The comments
in the file tell you how to do it."
-
"If you have a Duemilanove board with the ATmega168, use the
Diecimila project. If you have the Duemilanove with the ATmega328 or 328P, use
the Uno project."

Message Wheel - CH Ting
Ting will discuss and
demonstrate a message wheel using an Arduino Uno board mounted on a bicycle
wheel. As the wheel rotates, 8 LEDs spell out letters of a message.

MyForth on Arduino Hardware - Charley
Shattuck
"This is a very minimal approach to compiling programs using
Forth for an Arduino board. This is a tethered Forth, using Linux resources
such as Vim for colorful editing,
AVRDUDE for downloading,
Minicom for interactive
testing, and Gforth for
target compiling. It is purposely not ANSI standard, instead borrowing from
colorForth and arrayForth. The main point was to see how little I could get
away with doing and still have a usable system for programming an Arduino
board."
