Original Code Consulting
|MICAS-X is a new product by Original Code Consulting.It is a highly-customizable program for acquiring data from and controlling scientific instruments. MICAS-X provides a broad range of software infrastructure - features many atmospheric and scientific instruments need, while providing a framework for integrating the customized software required for a specific application.|
| OCC Program Prep is a
utility that assists in making autonomous data systems
function correctly. It can be configured to
execute any number of steps. Each step can perform
one of the following actions: Wait, Wait Until Daq
Device is Ready, Launch a Program, Sync to NTP Server,
or Sync to GPS. Typical scenarios for OCC Program
Prep are to wait until the operating system has fully
initialized the NI DAQ Devices before launching the data
acquisition program, and to synchronize the computer
clock to a reliable external time source before
launchint the data acquistion program. For more
information, see the OCC
Program Prep page.
It is not easy to make a correlation plot in LabVIEW in
which two quantities are graphed relative to each other,
with each point color coded according to a third
quantity. With the advent of XControls in LabVIEW
8, it became possible to implement such a graph in a way
that is easy for other programmers to use. This Correlation
Plot XControl (LV 8.2.1) (636 KB)includes an
example program showing how to use the XControl as well
as a short document describing the XControl and its
Version 1.1.1 posted 10/22/07 contains minor cosmetic improvements.
This program is available either as LabVIEW VIs (LV 6.0.2) (307
KB), LabVIEW VIs (LV 8.2)
(433 KB), an executable for LV
6.0.2 (685 KB) or as an executable for LV 8.2
(3.8 MB). The LabVIEW 6.0.2 VIs require the Utitlity VIs
available on the General
LabVIEW page and also require that LabVIEW to be
installed on the end-user's computer. (Also note that in
the LV version, it is possible for one of National
Instruments' VI's to become unlinked, depending on where you
install the VI's. To launch the help file display, this
program uses the Open URL in Browser.vi which is located under
LabVIEW/help/_browser.llb It may be necessary to relink
this VI to get the program to run.) The LabVIEW 8.2
souce code has the Utility VIs built into the same download.
The executable version does not require that LabVIEW be installed on the end-user's computer, but does require that the LabVIEW run-time engine be installed. The LabVIEW run-time engine is free and can be downloaded from National Instruments, by navigating through Download Software/Drivers and Updates/All Software Versions/LabVIEW/platform/Run Time Engine, or by going through their ftp site at ftp.ni.com and navigating through Support/LabVIEW/Runtime/(platform). (I cannot supply a direct link to their web download since their addresses are dynamic and it may be necessary to register in order to access the download. Registration is not necessary if you go through their ftp site.) Note that the correct version (6.0.2 or 8.2) of the Run Time Engine is required. If you download a different version instead, the executable version of the Gaussian Beam Calculator will not operate. If you already have one of the required versions of the LabVIEW Run Time Engine installed on your computer, then choose the appropriate version of the Gaussian Beam Calculator and you won't need to install the RTE again.
Version 1.2 of the Gaussian Beam Calculator, posted 20020128,
fixes a small bug in the Units menu that manifested itself
when previously-saved files were read into the program.
The help file describing the program (which is included in the downloads) can be viewed here.
| This VI (LV
8.2.1, 35KB) is used to calculate the angel in
radians between two lines in three dimensions that both
pass through the origin. In addition to the simple
calculation sub-vi, an example program (shown to the
right) is included to help visualize how it works.
Note that this example program uses the LabVIEW 3D
Graph, and so cannot be used in the LabVIEW Base
This program was updated to version 1.1 in February, 2008, to correct a wiring error in the example VI.
Note that the factor of 2.772589 scales the peak so that the width is expressed in terms of FWHM. If you wish other measures of the width, you can rescale the result or alter the VI as needed. Depending on your data, you may also wish to alter the calculations of the initial guesses for the coefficients. (E.g., you may need to calculated the DC Offset based on the first few and last few points of data, or you may want to smooth the data before calculating the intial guesses.)
Requirements: Since it is based on the Advanced Analysis package, this VI cannot be run from the LabVIEW Base package or the Student Edition. The Full Development System or a higher package is required in order to support the low-level routines used in this program. Also note that this VI calls the Error Cluster Generator, which is part of the UtilityVIs.llb described on the Utilities page.Version 2.0, posted 20020914, is significantly revised and improved. In order to improve performance, the Target Function was rewritten so that it is called once for the entire array of data, rather than once for each point. This and other improvements were suggested by Christian Altenbach and Don Wagner. Christian and Don also assisted generously in testing these algorithms and made numerous helpful suggestions. Version 2.0 is significantly cleaner and more powerful than the older versions previously posted here. This version includes support for standard deviations for each data point, numerically calculated derivatives as well as analytical derivatives, and more than one target function definition. (The original Exponential function in NI's example is included as well as the Gaussian fit.) VI's written by Christian and Don use dynamically called target functions, which is a great way to support a large number of fitting functions. This version uses a type-def enum control to select which target function to use. It is fairly easy to edit the enum and the Target Function VI to add a small number of additional functions. In addition, this direct call is slightly more efficient than the dynamic call.
|Mass Calculator (LV 6.1, 51 KB) is a simple program that adds up the integer masses of any atomic combination. The screen is laid out similarly to a common arithmetical calculator, but instead of numeric keys, there are a set of keys similar to a periodic table which correspond to each of the elements. The element symbols and masses are stored in text files that are included in the zip file download. Also, note that the entire Mass Calculator program is included with the Peak Identifier download above.|
