Hi, folks. I ported by RF24 library from Arduino to Maple. This makes it easy to use these low-cost radios for RF communication between nodes.
Details on my blog:

I think perhaps we need a new part of the website, or better wiki support, for sharing and downloading libraries and projects...what do you think?
Unfortunately, we are far too shortstaffed to take on any serious web-dev effort, but pershaps something simple?
IMO a wiki is fine for this. The Arduino Playground is out of control huge with way too many libraries, but it still does the job. I can add it to http://wiki.leaflabs.com/index.php?title=Libraries
The one thing you could do that would help lots is unify the sign-in between the forum and the wiki.
By the way, Maple is now my preferred testing platform for this library (and soon will probably be so for the others, too.) It's super-handy to be able to run cxxtest directly on the hardware.
Hi, mrkriss. Thanks for trying it out. Please provide details on the errors you are finding. Also, what board are you using, and are you compiling from the command line or IDE? Ideally, open an issue on github. It works for me on Maple Native from the IDE, but that's a fairly limited sample set.
Note that ONLY the "pingpair_maple" example is compatible with Maple. The rest are Arduino only. It would not be difficult to port the others to Maple. I chose not to do that because it would clutter them up with #ifdefs which would complicate learning for Arduino users.

I have too problem with compile pingpair_maiple.pde
/tmp/build8948615837160357210.tmp/main.o: In function `_write':
multiple definition of `_write'/tmp/build8948615837160357210.tmp/syscalls.o:/home/Maple/maple-ide-v0.0.12/hardware/leaflabs/cores/maple/syscalls.c:155: first defined here

Listing of all compiler output follows.
Note: <BUILD> stands for the temporary build directory used to compile your sketch, which is:
/tmp/build8948615837160357210.tmp
Also note that because of preprocessing, line numbers won't match up exactly. We're working on a fix.

Thanks for trying this out, guys. Ok, I just pushed up a fix. Here's the deal. Maple out of the box doesn't make it easy to enable printf. Both the library and the example use printf extensively to give debugging information. The old version of the example REQUIRED you to make a change to Maple, and didn't document it very well. The version I just pushed up does not require the change, but instead prints out a warning block of text that you won't get debugging information.
EDIT: The change needed to Maple is submitted as pull request #37: https://github.com/leaflabs/libmaple/pull/37
