Hi all, I've been putting together some educational bits and pieces for a class that I am planning at a local Maker spot. In the process of doing this I decided to look into Arduino because it is very popular.
I have written a light implementation of the Arduino base SDK for the Parallax Propeller. The intent was to give Arduinites the ability to explore the Propeller with some familiar tools and functions, so you don't have to completely relearn another microcontroller to dabble with it.
This is not a retargeting of the Arduino development environment, it's a class object that implements many of the functions listed in the Arduino online reference.
I refer to it as a light implementation because it doesn't seek to be perfectly compatible or have the same limits as the Arduino SDK. That said, you can do all of the things in the Arduino SDK with native SPIN objects, better, than my compatibility class.
I endeavored to make the SPIN object not require any dedicated COGs, so you can use all of these methods in one COG, giving you 8 simultaneous Arduino light micros.
You can find my class here: http://obex.parallax.com/objects/810/
I have also posted a topic on the Parallax forum describing what functions are available here: http://forums.parallax.com/showthread.php?136273-Announcing-the-release-of-the-Arduino-LIGHT-object
You may wonder why I wanted to write for the Propeller?
Every 5 or 6 years I have explored what was new or the accepted standard in micros. In 2001 I was developing on the 16-bit Hitachi H8/3664 micro in C. In 2006 I tinkered with the Atmel SAM7 ARM mcu, 55Mhz, 55Mips, builtin USB, etc. A few months back I looked into the current lot and found it was really Arduino & Propeller. What drew me to the Propeller was the on-chip hardware to generate video signals. Each COG can generate a video signal independently. Also, aside from the counters, there isn't any fiddly subsystems to have to figure out by reading a cryptic datasheet that's 300 pages, 15 times. All peripherals are implemented in software, relying on the speed of the micro to implement serial, SPI, and just about any other protocol you could want. The Propeller chip is $8, is available as a 40-pin DIP, only needs an EEPROM and crystal, and is 160MIPS.
