PCIe-6509 Examples

NI installs example code with your software or driver that demonstrates the functionality of PCIe-6509, helps you advance your knowledge, and provides building blocks for your own applications.

While the experience can differ slightly across products and versions, examples generally install with your NI product or driver and can be accessed from within NI software.

NI-DAQmx includes a collection of programming examples to help you get started developing an application. You can modify example code and save it in an application. You can use examples to develop a new application or add example code to an existing application.

The following NI-DAQmx example programs supported on the PCIe-6509 demonstrate common functions and operations:

Table 6. Common PCIe-6509 Examples
Example Name Description
Digital - Change Detection Demonstrates how to acquire a continuous amount of digital data based on the changes of an external signal across one or many lines on either the rising or falling edges.
Digital - SW-Timed Input Demonstrates how to acquire the state of digital lines based on software timing.
Digital - SW-Timed Output Demonstrates how to generate digital output data using software timing.

    NI Example Finder launches.
  3. Optional: Configure NI Example Finder for LabWindows/CVI.
    1. Click Setup to open Configure Example Finder.
    2. In Configure Example Finder, click Software, then select LabWindows/CVI, and click OK.
    NI Example Finder updates with all the examples for LabWindows/CVI.
  4. Search example VIs for your product.
    OptionDescription
    Click the Browse tab. Choose Browse when you want to drill down through folders to find examples organized by task category.
    Tip Examples installed with NI drivers or third-party drivers are often found within the Hardware Input and Output folder. Examples installed with toolkits or modules are often found within the Toolkits and Modules folder.
    Click the Search tab. Choose Search when you want to find examples by searching for topics, products, or modules relevant to your application.
  5. Double-click a folder or example to open.
    Tip You can modify an example VI to fit your application. You can also copy and paste from one or more examples into a VI that you create.
