Sensinode platform example and test applications
- by Zach Shelby (zach@sensinode.com)
Some more examples by George Oikonomou - Loughborough University

blink-hello, event-post, timer-test
<oikonomou@users.sourceforge.net>
This directory contains example and test applications for
Sensinode CC2430 based devices. By default it is set to use the
sensinode platform:
@ -32,8 +37,21 @@ These make options are defined in /platform/sensinode/Makefile.sensinode
Descriptions of applications:
hello_world A simple hello world app.
clock_test Test and example of sys/clock.h related features.
rf_test_tx Test for transmitting packets
rf_test_rc Test for receiving packets
hello_world A simple hello world app.
clock_test Test and example of sys/clock.h related features.
rf_test_tx Test for transmitting packets
rf_test_rc Test for receiving packets
Recent Additions:
udp-ipv6 UDP client-server example over uIPv6. Uses link-local and global
addresses. Button 1 on the client will send an echo request.
broadcast-rime Just a broadcast rime example, slightly modified
sensors Demonstrating button and ADC functionality
cc2431-location-engine
Example demonstrating the usage cc2431 location engine (blind node)
N.B. Not all sensinode devides have a cc2431
event-post Demonstrating the interaction between two processes with custom events
blink-hello Hello World with LED blinking.
timer-test Same as clock_test above + testing the rtimer-arch code
border-router 802.15.4 to SLIP bridge example. The node will forward packets
from the 15.4 network to its UART (and thus a connected PC over SLIP)

border-router example for sensinode devices.
This example is meant to be used with tunslip6 in tools/
- Build the code and load it onto your node
- Connect your node to your PC over USB
- run:
sudo ./tunslip6 <address v6>/<prefix>
This will setup tun0 on your PC over device /dev/ttyUSBx. The address
argument should contain the v6 address that you want to assign to tun0
The node will use this address to obtain the network prefix
for example:
sudo ./tunslip6 aaaa::1/64
This will use aaaa:: / 64 as the prefix for the 15.4 network.

/**

*
* B1 turns L2 on and off.
* B2 reboots the node via the watchdog.
*
* The node takes readings from the various sensors every x seconds and
* prints out the results.
*
* We use floats here to translate the AD conversion results to
* meaningful values. However, our printf does not have %f support so
* we use an ugly hack to print out the value by extracting the integral
* part and then the fractional part. Don't try this at home.
*
* Temperature:
* Math is correct, the sensor needs calibration per device.
* I currently use default values for the math which may result in
* very incorrect values in degrees C.
* See TI Design Note DN102 about the offset calibration.
*
* Supply Voltage (VDD) and Battery Sensor:
* For VDD, math is correct, conversion is correct. See DN101 for details if
* interested.
* Battery reports different values when we run it many times
* in succession. The cause is unknown.
* I am fairly confident that I have captured the connections on the
* device correctly. I am however accepting input/feedback
*
* Light Sensor (Vishay Semiconductors TEPT4400):
* I am uncertain about the math. This needs testing. All I know is
* that 600lux = 0.9V and that the relation is linear. See inline for
* more details
*
* Accelerometer (Freescale Semiconductor MMA7340L):
* Math is correct but the sensor needs calibration. I've not
* attempted one cause the reported values differ per device.
* Place the N740 with the logo facing down to get 1g on the Z axis.
* Place the antenna side facing down to get 1g on the Y axis
* Place the N740 on its longer side while looking at the antenna and
* the D connector. Antenna on the bottom, D connector on the top.
* This should give you 1g on the X axis.
*
* Make sure you enable/disable things in contiki-conf.h

A very simple sniffer for sensinode devices.
The cc2430 RF driver supports outputting all captured packets in hexdump
format. We turn this on, and turn everything else off. We use a stub RDC
driver to make sure no incoming packet ever goes up the stack and no packet is
ever sent out.
We only initialise the radio driver instead of the entire stack by over-riding
the default netstack.c with the one in this directory.
You can then pipe the sniffer's output to the n601-cap util, which will convert
the hexdumps to pcap format, which can in turn be piped to wireshark. This is
handy if we want live capture of the lowpan traffic from wireshark. See the
README in n601-cap for more details
