Download Driver Plug Amp; Play

PnP requires support from device hardware, system software, and drivers. Initiatives in the hardware industry define standards for easy identification of add-in boards and system components. This Windows Driver Kit (WDK) documentation focuses on the system software support for PnP and how drivers use that support to implement PnP.

I'm just getting in to LabVIEW and see that when I go to download instrument drivers, there are several listings. One is Plug and Play and the other is typically IVI. What is the difference? So far I've been through the Lesson #1 and Lesson #2 Basic Developer courses, but we haven't touched on the use of downloaded drivers.

I have about 7 devices (speakers, mouse, etc.) that are all USB. They all came with CD's containing drivers for it. My question is, why do they? All 7 of these devices have run just fine on every computer I've ever owned (XP, Vista, Ubuntu, 7) without me even bothering with installing the included drivers disk. All the functionality works. My first thought was that it was just downloading it off the internet but even land-locked computers (i.e. no internet) were able to successfully utilize the devices without me installing.

Every device you own uses a driver to communicate with the OS. In most modern operating systems, the default built-in drivers are enough to cover a myriad of devices, such as keyboards, mice and speakers.

But once in a while, a device comes along that the OS engineers haven't designed for. I.e., my Fitbit - a USB/wireless pedometer. In that case, you need to install a driver in order to introduce the device to the OS and allow them to interact.

Another common scenario is a known device with a novel feature (such as a mouse with extra buttons, a keyboard with special function keys etc.) in which case the built-in driver will only cover the known features, and deprive you of the use of the extra functionality - until you install the dedicated driver.

The new Windows 7 "Device Stage" feature can display an image of several classes of connected devices. Windows 7 offers to download such information from the Internet but it is possible software CDs have that information too.

One more scenario that might not quite as common today is support for older operating systems. Back in the dark ages when USB was new, there was an ongoing race between device builders and the OS vendors to invent and support device classes. It was common to need to install a driver on a Windows 98 or Windows Me machine in order to support any USB device more exotic than a mouse, for instance. Since the internet wasn't quite as pervasive then either, the cost of a mini CD was far less than the cost of a returned device or a tech support call, so they just packed CDs with everything.

Plug-and-play products are complete, ready-to-use IGBT drivers that have been tightly matched to a specific device. Drivers are available to cover a large selection of high-power and high-voltage IGBT modules with reverse voltages from 1200 V to 6500 V. All plug-and-play drivers are equipped with DC/DC converters, short-circuit protection, active clamping, supply monitoring and more.

Longer answer: Unless the device is brand new, strange, or just something that fell through the gap, anything plug and play on Windows will likely be plug and play on Ubuntu. Don't assume, though!

Plug-n-Play is an interesting term. There are multiple kinds, each doing different things - for example, a device like a keyboard that needs no special driver at all is plug-and-play, but technically so is the device that downloads its drivers through Windows Update.

Anything in the "generic" category will almost always work on Linux straight away. You should be able to plug in almost any keyboard, mouse, flash drive, etc. without any issue. You may get the rare device that doesn't want to work due to some quirk, but these are few and far between.

Things that download drivers in the background (quite a few webcams, printers, etc.) are more of a mixed bag. In my personal experience, these have almost always worked fine on Linux, but this is not always the case. You may need to install printer drivers or other things manually if the Linux kernel doesnt come with a working generic.

A pretty simple question, but it is important to me. If I get a TM warthog HOTAS, can I simply plug it into my USB ports and go play, or do I need to download drivers (or get them from a cd if it comes with one) and install them?

As far as i know, its plug and play. The software related to it is mostly a script editor to make full use of flip switches etc that is not possible via the in-game controls. If that does not bother you however, it should work just fine without downloading any software.

You are not completely right. In the a-10c everything works as intended. But, when you want to set the flaps of the su-25 to the flap selector switch you wont be able to set three states. Only the up and down position work without target software. The middle position is the off position of the switch and DCS will require a driver to tell it is a programmable switch position aswell.

This document, which describes the standards and practices for LabVIEW Plug and Play drivers, is intended for driver developers and describes the standards for structuring VIs, instrument I/O, style, and error reporting. It also describes instrument driver components and how to integrate these components. In addition, this document describes a process for developing useful instrument drivers.

Other resources for instrument driver developers include the instrument driver templates and the Instrument Driver Guidelines, both of which are available from the NI Instrument Driver Network (ni.com/idnet).

To use this document, you should have a basic understanding of instrument control and be familiar with the operation of LabVIEW. You also should be familiar with the with Virtual Instrument Software Architecture (VISA) application programming interface (API).

A LabVIEW Plug and Play instrument driver is a set of VIs that control a programmable instrument. Each VI corresponds to an instrument operation, such as configuring, triggering, and reading measurements from the instrument. Instrument drivers help users get started using their instrument from their computer and saves them development time and cost because users do not need to learn the programming protocol for each instrument. With open-source, well documented instrument drivers, end users can customize their operation for better performance. A modular design makes the driver easier to customize.

Using a standard architecture for all LabVIEW instrument drivers has the following benefits:

The LabVIEW Instrument Driver Network contains instrument drivers for a variety of programmable instruments, including GPIB, USB, TCP/IP, VXI, RS-232, and PXI instruments. Instrument drivers contain high level VIs with intuitive front panels, so end users can quickly test and verify the remote capabilities of their instrument. They do not need to know low-level instrument control and instrument-specific commands and syntax. Users create instrument control applications by building VIs using instrument driver VIs as subVIs on their block diagrams.

Many programmable instruments have a large number of functions and modes. With this complexity, it is necessary to provide a consistent design model that aids both instrument driver developers as well as end users who develop instrument control applications. The LabVIEW Plug and Play instrument driver model contains both external structure and internal structure guidelines. The external structure shows how the instrument driver interfaces with the user and to other software components in the system. The internal structure shows the internal organization of the instrument driver software module.

The external structure illustrates how the instrument driver presents both an interactive interface and a programming interface. The application programming interface (API) is the set of user-callable instrument driver VIs used in end-user systems. For example, a manufacturer test system might make instrument driver calls to communicate with a multimeter or an oscilloscope.

The end user learns about the API through the instrument driver front panels. By interactively running the front panels of the instrument driver VIs, end users understand how each control affects the instrument. After they understand the settings, end users can incorporate the instrument driver VIs in their application.

The Virtual Instrument Software Architecture (VISA) I/O interface is the set of LabVIEW functions the driver uses to communicate with the instrument hardware. VISA is an established standard instrumentation interface that controls GPIB, USB, serial and other instrument buses. Refer to the LabVIEW Help for descriptions of VISA functions and controls.

Support VIs are VIs that you do not intend the end user to access directly. Therefore, support VIs are not part of the instrument driver API. For example, instrument drivers often call the Default Setup VI during initialization to set the instrument in a state that allows for robust instrument control by the rest of the instrument driver VIs. Only the Initialize and the Reset VIs use the Default Setup VI as a subVI, so it is considered a support VI.

The internal structure of the instrument driver defines the organization of the instrument driver VIs. All user-accessible API VIs are organized into a modular hierarchy based on instrument functionality.

The figure below shows the internal structure of LabVIEW instrument drivers. End users have the necessary granularity for controlling instruments properly in applications. For example, end users can initialize all instruments once at the start, configure multiple instruments, and then trigger several instruments simultaneously. Also, they can initialize and configure an instrument once, and then trigger and read from the instrument several times.

For end users, the model provides a consistent instrument driver model. After users understand one instrument driver, they can apply that knowledge to other LabVIEW instrument drivers. 2351a5e196
