+README for MultihopOscilloscopeLqi
+Author/Contact: tinyos-help@millennium.berkeley.edu
+
+Description:
+
+MultihopOscilloscope is a simple data-collection demo. This variant,
+MultihopOscilloscopeLqi, works only on platforms that have the CC2420.
+Rather than use CTP, it uses MultihopLqi (lib/net/lqi), which is
+much lighter weight but not quite as efficient or reliable.
+
+The application periodically samples
+the default sensor and broadcasts a message every few readings. These readings
+can be displayed by the Java "Oscilloscope" application found in the
+TOSROOT/apps/Oscilloscope/java subdirectory. The sampling rate starts at 4Hz,
+but can be changed from the Java application.
+
+You can compile MultihopOscilloscope with a sensor board's default sensor by
+compiling as follows:
+
+ SENSORBOARD=<sensorboard name> make <mote>
+
+You can change the sensor used by editing MultihopOscilloscopeAppC.nc.
+
+Tools:
+
+The Java application displays readings it receives from motes running the
+MultihopOscilloscope demo via a serial forwarder. To run it, change to the
+TOSROOT/apps/Oscilloscope/java subdirectory and type:
+
+ make
+ java net.tinyos.sf.SerialForwarder -comm serial@<serial port>:<mote>
+ # e.g., java net.tinyps.sf.SerialForwarder -comm serial@/dev/ttyUSB0:mica2
+ # or java net.tinyps.sf.SerialForwarder -comm serial@COM2:telosb
+ ./run
+
+The controls at the bootom of the screen allow yoy to zoom in or out the X
+axis, change the range of the Y axis, and clear all received data. You can
+change the color used to display a mote by clicking on its color in the
+mote table.
+
+Known bugs/limitations:
+
+None.

+TEP 113: Serial Communications, TEP 119: Collection.
+
+Notes:
+
+MultihopOscilloscope configures a mote whose TOS_NODE_ID modulo 500 is zero
+to be a collection root.
