If you regularly use the Arduino, but want to explore the versatile multi-core environment of the Parallax Propeller, here’s a code project of interest. Perry Harrington has written a Propeller SPIN code object to emulate many of the functions found in the Arduino SDK.
Perry describes his code:
This is a basic _light_ implementation of the Arduino SDK for the Propeller. It is intended for newbies to get acquainted with the Propeller. There are many useful SDK functions implemented, things like PWM, tones, shiftIn/shiftOut, bit setting routines and math routines. This object is intended as an easy way for Arduinites to explore the Propeller, it is not intended as a substitute for the many great SPIN/PASM objects that implement much of these functions in a more robust and thorough manner.
To clarify, a review of the code confirms that this object provides a number of functions using “Arduino terminology” which you can use with the standard Parallax Propeller IDE. It is not an Arduino GUI that you can fire up and use with Propeller as if it were an Arduino. Nevertheless, it can help to ease Arduino users into the broader SPIN coding environment.

Nice! I’m happy to see this has gained interest. I know the Propeller heads in the forum were not really much interested, so this is great news to help spread the word.
