    A set of custom controls, following the trend of a more flat UI design. Heavily influenced by Google’s Material Design, though constrained by what can be done with available tools and options in LabVIEW. Uses icons from Google Material Design. — Buttons based on the system booleans (with hover effects). Icons can be added as decals (such as from materialdesignicons.com) — Matched sets of controls for numeric/string/enum/etc., based on Silver controls, but swapping out all ‘chrome’ for simple boxes and lines. — flattened versions of switches/sliders/arrays/graphs etc. Now on the LabVIEW Tools Network

    Package for working with JSON. Uses high-speed text parsing, rather than building an intermediate representation as with prior LabVIEW JSON libraries (this is much faster). Allows easy working with "subitems" in JSON format, or one can convert to/from LabVIEW types. Uses the new "malleable VIs" of LabVIEW 2017 to convert to any LabVIEW type directly. JSON text makes use of a form a JSON Path notation, allowing easy and rapid access to the subitems of interest. Requires LabVIEW 2017 and install by VIPM 2017 or later.

    There it is... finaly... Because the code given in the FTDI web page is not convenient, not working and haven't been developed by real LABview programmer, I decided to create a library for the I2C. a version for SPI will come soon. This library is free to use. If FTDI want's it in ther site, I do not allow you to publish it since you didn't help any of your customer with LABview. but of course feel free to publish this link.

    An extensive library for passing messages between parallel processes. Generalizes the communication method, allowing the message sender to use the method provided by the receiver. Supported communication methods include wrappings of simple queues, user events, and notifiers, as well a more complex channels such as a TCP server and client. In addition, one can configure simple forwarding addresses (“Observers"), which can send messages to multiple destinations, optionally with modifications such as adding a prefix to the message label, relabelling, or substituting a different message. Communication patterns supported include request-reply (asynchronous or synchronous), where the reply is sent to a "reply address" attached to the request, and register-notify, where one process sends a registration message to another in order to subscribe to a series of updates. Also supports scatter-gather, the gathering of replies from multiple senders into an array of messages. An option framework for dynamically-launched VI "actors" is also provided, including example templates, which can be accessed via the Tools menu (from an open Project, select Tools>>Messenger Library>>Create Actor from Template..). An "Actor Manager" debug tool is also installed under the Tools menu. Please note that this package has nothing directly to do with the NI Actor Framework (other than both packages are influenced by the Actor Model). ***Introductory Videos are on a YouTube channel.*** ***A great summary of many Messenger Library sources, provided by Bob W Edwards*** Original conversation on this work is here. Now hosted on the LabVIEW Tools Network (but note that the latest version will often be on LAVA) ***NOTE: latest versions require VIPM 2017 or later to install.***

    There it is. The complete library for the MCP2221A. I2c adapter, I/O in a single IC. I love that one. Let me know if any bug is found. I try to make that library as much convenient as possible to use. Two version available 32 bit and 64 bit. little note: to open by serial number, the enumeration need to be activated on the device first. (open by index, enable the enumeration) It needs to be done only once in the life time of the device. PLEASE do not take ownership of this work since it is not yours. You have it for free, but the credit is still mine... I spent many hours of my life to make it works.

    Here is the Hooovahh Array VIMs. This initial release contains 14 VIMs for manipulating array data, which are intended to replace OpenG functionality, but with the added benefit of data type propagation, and increased performance using newer array manipulation techniques. In later versions other Array manipulation functions were added moving all the OpenG stuff to their own palette. Most of the OpenG functions are unchanged, but a few use the newer conditional and concatenating tunnels. And a few functions have added performance based on other inputs. For instance the Delete Array Elements can operate in a more efficient way if the input indexes are already sorted. The Filter 1D array can also be more efficient if the input is known to not contain any duplicates. Because these packages contain VIMs, they require LabVIEW 2017 or newer. Having these functions be VIMs mean all functions work with various array data types. Included functions are: Conditional Auto-Indexing Tunnel Delete Elements from (1D or 2D) Array Filter 1D Array Index (1D or 2D) Array Remove Duplicates from 1D Array Reorder (1D or 2D) Array Reverse 1D Array Slice 1D Array Sort (1D or 2D) Array Convert 1D to 2D Convert 2D to 1D Find Subarray Force Array Min/Max Size Foreign Key Sort

    This package consist of a series of tools in native LabVIEW 2010 code. For encryption/decription the AES (Rijndael) routine is used with key sizes of 128, 192 and 256 bytes. The encryption supports the following block modes: EBC CBC CFB128 OFB For signing of string/packages it performs the SHA-1 and SHA-2 hashing, for MD5 hashing the OpenG functionality is used. The hash functions return a binary string and a hex-formatted string with the hash. The following hashes are supported: MD5 (via OpenG library) SHA1 SHA-2 224 bit SHA-2 256 bit SHA-2 384 bit SHA-2 512 bit For Hashed key authentication the HMAC functionality is provided based on the supported hash functions. The used functions are tested against NIST public test vectors. The use of these functions is not: secure the code does not try to protect it's memory nor the used keys. © Ton Plomp 2011 - No warranty implied.

    Copyright © 2007, David Saunders All rights reserved. Author: David Saunders --see readme file for contact information. Description: Provides an intuitive interface for tabular controls containing multiple data types. Users can use various controls and datatypes. Users can also use provided functions for registering and looking up type parameters by control (as well as by column, row, or cell). When you click on a cell, a correctly positioned and sized popup appears allowing for a controlled and intuitive input. Appears like it is a built-in feature, not an annoying popup window. Features: - Supports tables, listboxes, multicolumn listboxes, trees, and string controls. - Implements many data types : string, integer, float, color, ring, boolean, captioned string, etc. - Can use multiple tabular controls in same program with no programming changes - Can pre-register controls with certain data types - Register the entire control, or columns, rows, and cells. - Can edit the registered data type by registering again at any time - Allows for different font sizes - Works even on modal windows Instructions: Run the Demo program to see example usage. To recreate -- 1. Drop 'TSPopup.Popup Cluster.ctl' anywhere on your front panel. 2. Create program logic, similar to the demo MANDATORY elements a. TSPopup.Initialize.vi (register for the user event in your event structure) b. TSPopup.Lookup.vi (returns positioning information, looks up any registered controls) c. TSPopup.Show Popup.vi (called in a Mouse Down? event case) d. an event case for the user event output from (a.) e. TSPopup.Close.vi (called at end of program) OPTIONAL elements f. TSPopup.Register.vi (register controls with popup type parameters) g. TSPopup.Update Cell String.vi (provided to show how to change the cell string after popup is completed) 3. Bring the Popup Cluster to the front on the front panel. Otherwise the popup will show up behind some of the other controls on your User Interface. Limitations: - Can't programmatically bring popup cluster to front. Must do this manually. Change Log: 1.0.0: Initial release of the code. 1.0.1: Added another demo using dynamically changing data types in a tree Removed LV version specific event handling (only dealt with LV 7.1) Fixed bug where headers defaulted to have same type as their column/row Fixed cluster scanning from text Fixed ring to default to index 0 if string unrecognized Changed the background event monitor to always be hidden

    Introductory video now available on YouTube: Intro to SQLite in LabVIEW SQLite3 is a very light-weight, server-less, database-in-a-file library. See www.SQLite.org. This package is a wrapper of the SQLite3 C library and follows it closely. There are basically two use modes: (1) calling "Execute SQL" on a Connection to run SQL scripts (and optionally return 2D arrays of strings from an SQL statement that returns results); and (2) "Preparing" a single SQL statement and executing it step-by-step explicitly. The advantage of the later is the ability to "Bind" parameters to the statement, and get the column data back in the desired datatype. The "Bind" and "Get Column" VIs are set as properties of the "SQL Statement" object, for convenience in working with large numbers of them. See the original conversation on this here. Now hosted on the NI LabVIEW Tools Network. ***Requires VIPM 2017 or later for install.***

    One of the difficulties with editing XNodes without the license is that invoke nodes for the XNode class don't show any methods. This XNode acts pretty much like a real Invoke node, but it allows access to all possible methods. You can also right-click and replace it with a real Invoke node.

    JSON is a data interchange format (sometimes compared to XML, but simpler). There are multiple projects to create a JSON package for LabVIEW. This is yet another one motivated by this hijacked conversation originally about a different project to convert JSON into LabVIEW Variants. This project uses a set of LVOOP classes to match the recursive structure of JSON, rather than variants. It allows conversation to and from JSON. All functionality is available through two polymorphic VIs: Set and Get. In addition to Get and Set VIs for common data types, one can also convert directly to or from complex clusters via variant-JSON tools.

    This tool-set gives access to all the 1-wire TMEX functionality. I was able to access 1-wire memory with this library. It has all the basic VI to allow communication with any 1-wire device on the market. It needs to be used in a project so the selection of the .dll 64 bit or 32 bit is done automatically. It works with the usb and the serial 1-wire adapter.

    For a personal project, I needed to communicate between my computer and a SPI device slave device. So, I use a FTDI chip FT232h. I have adapted the library MPSSE I2C already available on this website to make it works for SPI. Warning ! VI are not 100% tested (especially Read functions), I provided it as it is.

    A pair of subVIs for connecting a cluster of enums and booleans to a set of options in a menu (either the right-click shortcut menu on control or the VI menu bar). Adding new menu options requires only dropping a new boolean or enum in the cluster. See original conversation here. I use this heavily in User Interfaces, with display options being accessed via the shortcut menus of graphs, tables, and listboxes, rather than being independent controls on the Front Panel. Relies on the OpenG LabVIEW Data Library.

    Document Generator v1.0.0 Copyright © 2011, Mark Smith All rights reserved. Author: Mark Smith LAVA Name: mesmith Contact Info: Contact via PM on lavag.org LabVIEW Versions: 2009 Dependencies: None Description: This class is used to generate a single summary document for any folder containing LabVIEW elements (controls, VIs, projects, classes, or libraries (lvlib)). It recursively traverses the folder structure and reads the documentation from all VIs (including custom controls) and the documentation attached to all front panel controls. The class uses that information to build a document in HTML, RTF (rich text), or plain text (ASCII) formats. HTML is the preferred format, since this is the only format that includes lvclass descriptions and also supports the creation of a hyperlinked table of contents (TOC). The user can choose to - use short or long formats - the long format includes the descriptions on all front panel controls - Include or exclude custom controls from the document - Include or exclude private members of a class or library - Include or exclude protected members of a class or library One might choose to exclude private and protected members if the intention is to create an API document for the class or library - enable or disable a dialog that warns that an existing html file is about to be replaced by the Document Generator Installation and instructions: Unzip and open the Document Generator.lvclass Examples: The UI.vi is an interactive interface for creating documents. The Generate.vi provides an API if the user wants to programatically call this utility. They can be found in the Public->Methods virtual folder. Known Issues: Any documentation read from the source elements (VIs, controls, projects, etc.) is treated as pure text. There is currently no provision for escaping characters that might be interpreted as control characters in HTML. Version History: v1.0.0: Initial release of the code.

    Copyright © 2009, Wojciech Golebiowski (vugie) All rights reserved. Author: Wojciech Golebiowski (w_golebiowski (at) tlen.pl) Name: BitMan (Bitmap Manipulation Library) Type: framework, library LabVIEW version: 8.2.1 Description: Bitman library is designed for image processing based on a specially-defined structure to store the image, and a system of filters. It is not only a set of tools performing specific operations on images, but also a framework to help create your own image processing functions with a mechanism called "dynamic filters". Library contains few basic built-in filters. Their design concentrates on the versatility, ease of use, and the clearance of the code. This results in a decrease of efficiency and consequently, processing of large images using standard filters may be slow. But this is not a limitation of the framework and it is possible to create user filters, which may - as a more specialized - operate much more efficiently. Built-in filters are good for processing of relatively small images and can be used to support programming user interfaces, operations on the icons, creating graphical documents, etc. Library was written using object-oriented programming techniques (LVOOP). Installation Libraries can be used after unpacking it anywhere on disk. Access to all of the features is possible then by opening the library file "BitMan Lib.lvlib". However, it is most convenient to copy entire BitMan directory to the directory \user.lib. After the restart of LabVIEW on a pallet, in the User Libraries, sub-palette "BitMan" will appear. Documentation A description of all VIs from palette is available in the file "docs\BitMan docs.html". Descriptions are also included (for all functions) in the Documentation section of the VI Properties dialog, as well as for more important front panel controls and, as such, are available through the LabVIEW context help. Examples Examples of applications can be found in the directory "examples" (examples of the use of the library itself) and the directory "examples\Dynamic Filters" (examples of the creation of filters). Examples along with descriptions in the diagrams are an integral part of the documentation. Functionality The most important class it the Bitmap class. It contains structure for storing an image (the description of the structure may be found in documentation under Bitmap type.ctl) and the basic access methods. The main assumption of this structure is to store the image in three-dimensional U8 array, where subsequent dimensions mean respectively height (y coordinate), width (x) and subsequent color channel. Number of channels in the image depends on the bit depth, additionally you can define any number of user channels. It is possible to store pictures 1 -, 4 -, 8 -, 24 - and 32-bit, while the 32-bit means here CMYK color model, rather than - as is sometimes used - RGB images with transparency . Transparency (the so-called alpha channel) is stored in a separate field of the structure. Support for CMYK images is not fully implemented yet. The processing of images is done by the use of system of filters implemented in General Filter class. This class stores a reference to strictly typed VI processing an image and its runtime parameters. The filter is launched with Filter Run method, which uses the dynamic call mechanism. Filter runtime parameters are stored in the object as a variant variable for unified method for passing them. Users can create their own filters in two ways: by using methods of Dynamic Filter class and filter template or by creating a new class inheriting from General Filter class. It is also possible to create a function-specific interfaces for the use of filters as the normal LV function. Inheriting and transparent interface is the way buit-in filters work, so they are also a specific example of use of the library. Template to create your own filters may be found in "typedefs". Using of dynamic filters is supported Library Filter class designed for managing filters. It makes use of the functional global mechanism for storing and providing access to pre-loaded filters with assigned names. It can call the filters by using short names anywhere in the code, without a burdensome wiring of filter objects. Another supporting class is Bitmap With Filters class, inheriting from the Bitmap class and extending its functionality with a possibility of using a sequence of filters. More detailed descriptions of individual functions and applications can be found in the above mentioned documentation and examples.

    Copyright © 2006, dsaunders All rights reserved. Author: dsaunders --see readme file for contact information Description: Converts a pixel coordinate to an array index. Returns an array of indices with a length equal to the number of array dimensions. Also returns if the point is within the content rectangle (not on the caption, scrollbars, etc.) Works on any N-dimensional array regardless of visibility of caption, label, index display, or scrollbars. Designed to be used on mouse events that provide the mouse coordinates. Limitations: Property nodes do not indicate the array border width, nor if the user has chosen to display an element gap. These inputs are thus provided on the VI. Version History: 1.0.0: Initial release of the code.
