Picture of Propeller Platform

What is the Propeller?


The Parallax Propeller is a 32-Bit 8-Core microcontroller.  Chance are you've already seen a few Propeller Powered projects like:

OpenStomp Coyote-1: open source digital guitar effects pedal


Music Demo (.mp3)
(Website)



The Replica 1, an Apple 1 Clone


(website)


ybox2, DIY Networked Set-top Box


(website)

and plenty more.  The Propeller is commonly used because it's high performance, has easy video output, and offers a lot of I/O.

So What is the Propeller Platform?

The Propeller Platform puts the Prop on a circuit board with voltage regulators, memory, a crystal, and connectors to other modules.  It's a lot like the Arduino with a few improvements on the basic idea;

1 - Modules (a.k.a. shields) can be connected to each other on top and bottom. For example, you might have a Propeller module in the middle, an LCD UI on the top, and a prototyper on the bottom.

2 - Pin spacing is .1". The space between sockets is .2", too. This makes the Platform compatible with breadboards, and it lets you use Platform modules in combination with other project boards.

3 - The board footprint is 3.8" x 2.5", which is the same footprint as ExpressPCB's MiniBoard service, so adding your own custom module is inexpensive and straightforward.

4 - They're well documented. They're featured in Jon Williams' column in Nuts and Volts and the Propeller Platform Module will be the basis for many of projects described in his upcoming columns.

5 - They're Public Domain. Module designs use the MIT license, giving you more flexibility than more restrictive licenses like Creative Commons Share-Alike. Templates and specifications can be downloaded here.

The Propeller Platform is available as a kit or pre-assembled from Gadget Gangster.


Build time is about 45 minutes. Get started by going to the next step!

Just put mine together this week and had my first led blink a few minutes ago...great instructable!

Awesome instructable and very easy to follow for the gumbies out there, like me, with limited knowledge but just like to tinker

Thanks! It's easy to put together and a lot of fun to program.
is this a instructables, looks more like an advert.

It's a howto - I sell a kit to put it together, but you're free to build it yourself - all the parts are commonly available and the pcb design is open source (you can download it on the project page).

The 6 on the Arduino are very usefull . It would be very nice for beginners to find such connectors on the Propeller Platform .

I used Sigma Delta program or an ADC chip with the Propeller but I think the Arduino connection is easier to use. cats92

For sure. I do like how you can do ADC with any of the pins, though. I wonder if maybe the prop has better resolution? You can do 16 bit at 1KHz, or 10 bit at 78KHz. I wasn't sure what the resolution for the Arduino is.

For the Propeller, all the I/O are equal, every pin can function as input or output.

That said, doing ADC on the prop requires a simple circuit. Take a look at ray's writeup on how it's done.

Very nice instructable!

The main problem with parallax propeller is that the software is only available for Windows. Otherwise, as a hardware platform, it is excellent.

There's no official Mac / Linux support, but there are a few unofficial compilers - Brad's version is pretty good.
