Propeller Programming
Assembler, Spin, and Test Driven Development
This book is 99% completeLast updated on 2017-08-12
This is an introduction and tutorial for programming the Propeller with a particular focus on using the Propeller Assembler language (PASM). The Propeller microcontroller from Parallax, Inc., is a powerful device that is used in many educational and hobby/maker applications. Here I introduce programming the propeller in Spin and C and then show how to integrate PASM language when speed of execution is important. I use a data compression example to motivate the tutorial.

About the Book
The Propeller microcontroller is a powerful multi-processor chip that can be programmed in either a high-level language (C or Spin) or a much faster Assembly language (PASM). The prop is used in many educational projects and in hobby/maker applications as well is in a number of commercial products.
In this book, I use a data compression/decompression application to introduce PASM to the reader. First I go through the full algorithm is Spin and in C and then translate it to PASM. That way, if you know a high-level language, you can map the PASM steps to something familiar.
Integrating C and PASM code has particular challenges that I go through in detail.
I use Test Driven Development throughout, which is a powerful technique for validating your code.
I include a chapter on hardware interactions (setting and reading pins).

Earn $8 on a $10 Purchase, and $16 on a $20 Purchase
We pay 80% royalties on purchases of $7.99 or more, and 80% royalties minus a 50 cent flat fee on purchases between $0.99 and $7.98. You earn $8 on a $10 sale, and $16 on a $20 sale. So, if we sell 5000 non-refunded copies of your book for $20, you'll earn $80,000.
(Yes, some authors have already earned much more than that on Leanpub.)
In fact, authors have earned over $15 million writing, publishing and selling on Leanpub.
