Preface
Preface
Thank you for purchasing a Propeller chip. You will be spinning your own programs in no
time!
Propeller chips are incredibly capable multiprocessor microcontrollers; the much-anticipated
result of over eight years of the intense efforts of Chip Gracey and the entire Parallax
Engineering Team.
This book is intended to be a reference guide to Propeller chips and their native programming
languages, Spin and Propeller Assembly. For a programming tutorial and Propeller Tool
details, please refer to the on-line help that is installed with the Propeller Tool software.
Have fun!
Despite our best efforts, there are bound to be questions unanswered by this manual alone.
Check out our Propeller chip discussion forum – (accessible from www.parallax.com via the
Support → Discussion Forums menu) – this is a group especially for Propeller users where
you can post your questions or review discussions that may have already answered yours.
In addition to the forum, visit the Propeller Object Exchange (obex.parallax.com) for free
access to hundreds of Propeller objects made by customers and Parallax Engineers. Besides
being immediately useful for your own applications, Propeller objects written by various
authors are a great resource for studying techniques and tricks employed by the very active
Propeller community.
Editor’s Note: About Version 1.1
The major content additions, corrections, and deletions that were made to Propeller Manual
v1.0 to produce this edition are highlighted in the PDF version of this document of Propeller
Manual v1.1. We recommend that if you previously read the original edition of the Propeller
Manual. A complete record of changes can be found in the Propeller Manual Supplement
and Errata v1.4. Both documents are available for download at www.parallax.com/Propeller.
Most significantly, the former Chapter 2: Using the Propeller Tool, was moved to the
Propeller Tool’s Online Help system where it can be updated frequently to stay in sync with
the enhancements to the development software. Likewise, the former Chapter 3: Propeller
Programming Tutorial was also moved to the Propeller Tool’s Online Help system where it
can be expanded more readily.
