Labview is a graphical programming language for instrumentation control and operation. It is in fact much more than that though. It is a new way of programming based around the principle of dataflow programming. In Labview the code is broken up into various nodes called sub VI's. There is no practical difference between a sub VI and the main VI or program other than the fact that the one is used inside the other. The key to dataflow programming is that a given sub VI must wait till all of its inputs are valid before it can process that node. Labview supports true preemptive multithreading provided of course that the operating system Labview is running on also supports it. What this means is several VI's can run simultaneously improving the speed and overall performance of the system.

Example Sound Card Based Programs

• Spectrum Analyzer(A simple spectrum analyzer using a sound card. It also does a running spectrogram.)
• Frequency Response(File Missing.)Uses sound card as signal generator and A/D.
• Send Receive 44.1 monoThis VI records and playbacks a single channel simultaneously
• Spectrograms and MiscThis vi computes a spectrogram and displays them on one graph. It also shows the time domain as well the general shape of how power is varying over time.

Miscellaneous Other Programs

• Fast Interval TimerA program to run something at an arbitrary rate, including less than a ms timing. Intended as part of a larger program.
• Shift Register Arrays Example (effectively creates a variable depth shift register for 1d arrays.)
• Active X Mp3 Player
• Demo of various graphs
• Plot Cursor Example (Draws a line between plot cursors by extracting cursor positions.)
• Jpeg Encryption Demo
• Steganography Demo
• Differential Cryptanalysis Demo
• Paint a picture with Labview -- Demonstrates either how to waste an evening coding, or how to use a lot of different aspects of Labview.
• Some Finite Difference Time Domain programs

Advanced Programs

• Labview LiDIA libraryAn under development library to access the LiDIA multiprecision library for Linux from inside Labview including elliptic curve functions(Documentation inside zip file)
• FE2D (Two Dimension Finite Elements (Contains a complex program which demonstrates many advanced Labview features.)
• Demining
• Alarm Clock This vi simulates an alarm clock. This system attempts to simulate how a real-time operating system would handle the tasks of running this alarm clock, although due to system complexity and time constraints it is only partially accurate.
• DES(beta1)This code is my first working build of code to execute the Data Encryption Standard. It is an old, but still used 56 bit key method of encryption. Run Test DES is the easiest way to test it at this time. Later versions will contain more functionality. It will probably never be optimized for speed. I will probably create an entire page with DES information on it as time permits. I used the following links to design this code. They all appeared to be accurate at the time this was wrote.FIPS 46-2 (DES), Data Encryption Standard FIPS 46-3 (DES), Data Encryption Standard Nist 800-17 Modes of Operation Validation System The DES Algorithm Illustrated

Old Demining Based Labview code. These programs in general required windows XP and very specific hardware and software. They are unlikely to run as is. Still someone may find something useful about them since they demonstrate how to do a great deal.

• Field Test Panel -- Used for one of the last major tests on the system.
• Review Saved Data -- Something created to look at the results of a 2d scanning of the waterjet demining test area.
• Scan Grid -- One of the programs used to scan the entire test area and collect data. It of course includes some real time analysis.
