TOS_LOCAL_ADDRESS is set to the ID of each node, either by modifying the
program before uploading it to a physical node, or by the simulator. TOSSIM
apparently starts numbering at zero. If you run the simulation with two
nodes, you'd have one with TOS_LOCAL_ADDRESS equal to 0 and one with

The nesC compiler looks for components in several directories:
- The current directory
- Include directories passed on the command line (-I),
often by setting the CFLAGS variable in the Makefile
- Directories specified in your platform's .platform file @includes
-
Low Power Listening makes use of the function that "detects RF power" to
extend it's listening period just in case there's something else on the air.
I've hit a few problems with it but it will indicate when it detects power
(even if that power is un-receivable as a packet)

What you see is much more than just the CRC. It's the whole TinyOS

Hi Ben,
The garbage that you are seeing is the TinyOS message framing. The
output is really intended to be displayed with the PrintfClient. The

I "think" that the nodeID is used as the random seed so each
node should get a different sequence of values. However they
probably won't change from run to run. You might need to hack
into the random() function and add some noise from an open ADC

Unfortunately the two I2C pins are shared with the radio

Hi,
I think most logical inputs are high by default because of the internal

want to signal a low on the input, you have to pull it down (you might
