Phidgets are an easy to use set of building blocks for low cost sensing and control from your PC. Using the Universal Serial Bus (USB) as the basis for all Phidgets, the complexity is managed behind this easy to use and robust Application Program Interface (API) library.
As such, the Phidgets Labview VI features a very simple and easy-to-use set of VIs. At the simplest level, all you have to do to control a Phidget is explained in this section.
For illustration purposes, Phidget Accelerometer will be used.

Note: For a more specific illustration on different phidgets, users can refer to different examples accordingly. |
Open the diagram of the "Single control example.vi" under the "Accelerometer" folder.
Phidgets can be programmed into 3 steps:
<Step1> Initialize the Phidget. This includes opening a Phidget hardware, creating a Phidget handler or setting up parameters of a Phidget.
Users can also acquire other information in this step. For more details, please refer to the example called "Remote Example.vi" under "TemperatureSensor" folder.
If users want to open Phidgets over the network, a PhidgetOpenRemote and AcceCreate functions will be called instead of AcceOpen.
<Step2> Perform any execution related with the Phidget. This includes data acquisition, device control, event execution etc.
<Step3> Close the Phidget. This may include closing the device, releasing all the resources or freeing a Phidget handle and an error handler.
