Description:
-Oscilloscope is a simple data-collection demo. It periodically samples the
-default sensor and broadcasts a message every 10 readings. These readings
-can be displayed by the Java "Oscilloscope" application found in the java
-subdirectory. The sampling rate starts at 4Hz, but can be changed from the
-Java application.
+Oscilloscope is a simple data-collection demo. It periodically samples
+the default sensor and broadcasts a message over the radio every 10
+readings. These readings can be received by a BaseStation mote and
+displayed by the Java "Oscilloscope" application found in the java
+subdirectory. The sampling rate starts at 4Hz, but can be changed from

You can compile Oscilloscope with a sensor board's default sensor by compiling
as follows:
Tools:
-The Java application displays readings it receives from motes running the
-Oscilloscope demo via a serial forwarder. To run it, change to the java
-subdirectory and type:
+To display the readings from Oscilloscope motes, install the BaseStation
+application on a mote connected to your PC's serial port. Then run the
+Oscilloscope display application found in the java subdirectory, as
+follows:
+ cd java
make

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.
