This is an open source software project based on the original Chibi wireless protocol stack . This project ports the Chibi protocol stack to the Arduino platform so that people familiar with the Arduino will be able to communicate wirelessly using inexpensive IEEE 802.15.4 radios. Chibi means "midget" in Japanese and its appropriate for this stack because it strips wireless communications down to the fundamental operations of initialization, send, and receive. The stack relies heavily on the radio hardware to do most of the timing specific parts of the protocol which allows it to run without an operating system or a scheduler. This also reduces the size of the software which currently requires approximately 4 kB of flash memory and approximately 300 bytes of RAM. 2012-11-02 v0.60 Release
Also packed everything in a zip file you can download here: Link to 2012-11-02_chibiArduino_v0.60 2011-11-17 v0.55 Release
2011-11-17 v0.54 Release
Link to 2011-11-17_chibiArduino_v0.54
2010-12-28 v0.51 Release
Link to chibiArduino Usage Guide v0.51 2010-11-06 v0.50 Release This is the initial release of the chibiArduino wireless protocol stack. It's a wireless 802.15.4 protocol stack targeted at the Arduino platform. Link to 2010-11-06_chibiArduino_v0.50 Link to chibiArduino Usage Guide v0.50
Additional Examples This is a temporary storage area for new examples that I or others may write but have not made it into the current release yet. Wireless Button This example shows how to read a button input and generate a command to toggle an LED on and off on a remote node.

Awesome. I'm going to add that into the examples. I'll also be moving the code to github so it will be easier to add or modify things.

Gitub is nice to use once you get everything setup properly. I resisted moving over from Google Code for quite a while, but I'm a happy convert now.

Hello,
I'm interested in trying your automatic channel scanning with chibiGetChannel(). Can you post the entire .pde (or .uno) file as the comment is cutted at the end of your sketch? Thany you. report abuse

* Add this to chibi.h
