    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.

    I think I've finalized my example for the XNode UpdateState ability. This is a very important ability. Failure to properly manage the update process can have dire consequences.

    Version 1.10.6

    2,102 downloads

    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.

    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. Original conversation about JSONtext. Now on the LabVIEW Tools Network. Copyright 2017 JDP Science Limited

    Hi everyone, Since GRBL standard is open source, I decided to post my Library that I used in LabVIEW to interface a standard GRBL version 1.1 controller. Not all GRBL function has been integrated, but this is a very good start. Enjoy and let me know your comments. Benoit

    UI Tools v1.4.0 Copyright © 2009-2016, François Normandin All rights reserved. Author:François Normandin Contact Info: Contact via PM on www.lavag.org LabVIEW Versions: Created and tested with LabVIEW 2012 Dependencies: OpenG Application Control Library >= 4.1.0.7 OpenG Array Library >= 4.1.1.14 OpenG File Library >= 4.0.1.22 OpenG LabVIEW Data Library >= 4.2.0.21 OpenG String Library >= 4.1.0.12 LAVA Palette >= 1.0.0.1 Description: This package contains tools for designing user interfaces. A first palette helps create special effects using transparency of front panel. Using them allows to quickly create fade-ins or outs using linear or exponential variation of the intensity. A second palette contains VIs to calculate the position of GObjects for many purposes like alignment, snap, mouse follow, etc. A third palette contains VIs to create dialog boxes based on class instances. "Simple Error Dialog" and "Simple Selection List" are featured with or without backrground blackening effect. A fourth palette includes some VIs to move objects programmatically on the front panel, using a basic deceleration algorithm to provide an impression of a smooth movement. The packaged VIs are all namespaced using a suffix “__lava_lib_ui_tools” which should not conflict with any of your own code. Includes: Front Panel Transparency (Fade In & Fade Out) Utilities (Alignment, Snap) Dialog (OOP based, extensible) Engine (Beta) for object movement Instructions: This package is distributed on the LabVIEW Tools Network (version 1.3) and updates are on LAVA (1.4). It can be installed directly in the addon folder of any LabVIEW version from 2012 to now. The addon installs automatically under the LAVA palette of the addon submenu. License: Distributed under the BSD license. Support: If you have any problems with this code or want to suggest features, please go to www.lavag.org and navigate to the discussion page.

    This XControl has the nice feature that a Calendar control should give you. Multilanguage support by property node. The input and output are Labview Time Stamp. When selecting a date, the date in the calendar become light blue. Please you receive this XControl for free. The minimum you can do is to rate it.

    Since the standard Tick Count VI has very limited resolution, I made a simple timer using the QueryPerfomanceCounter methods in the windows kernel32.dll. The output is the time in seconds as a double precision value.
