The LabJack U12 installer contains 9 example applications:
-
LJconfig: Lists all LabJacks connected to the USB and allows the local ID to be set on each.
-
LJcounter: Reads the LabJack counter and provides the current frequency or count.
-
LJfg (Function Generator): Outputs basic waveforms on AO0 (analog output zero).
-
LJlogger: Saves data to disk, writes data to an HTML page on the Internet, and performs various actions (including email) on trigger events.
-
LJscope: Simulates an oscilloscope by reading data from 2 AI channels in burst mode.
-
LJstream: Uses stream mode to read, graph, and write to file, 4 AI channels.
-
LJtest: Runs a sequence of tests on the LabJack itself.
-
LJSHT: Retrieves and records data from 1 or 2 EI-1050 digital temperature/humidity probes.
-
LJSHTmulti: Displays data from up to 20 EI-1050 digital temperature/humidity probes.
The LabVIEW source code for most of these applications is installed in the examples directory.
