Using Your Ni 6584R With A Labview Fpga Example Vi - National Instruments 6584R User Manual And Specifications

Using Your NI 6584R with a LabVIEW FPGA Example VI

The NI FlexRIO Adapter Module Support software includes a variety of example projects to help get
you started creating your LabVIEW FPGA program. This section demonstrates how to use an existing
LabVIEW FPGA example project and a basic universal asynchronous receiver/transmitter (UART)
interface to perform serial generation and/or acquisition with the NI 6584R. This example requires an
NI VHDCI-to-Eight DB9 cable. If you are operating an unterminated device, NI recommends that you
use external termination.
Note Examples available for your device are dependent on the device-specific minimum software
requirements. For more information about the minimum software requirements for your device, visit
ni.com/info
Each NI 6584R example project includes the following parts:
• A LabVIEW FPGA VI that can be compiled and run embedded in FPGA hardware
• A Host VI that runs in LabVIEW for Windows and interacts with the LabVIEW FPGA VI
Note In NI application software, NI FlexRIO adapter modules are referred to as IO Modules.
Complete the following steps to run an example that generates and/or acquires data.
1. Connect the VHDCI end of an NI VHDCI-to-Eight DB9 cable to Connector 0 (Ports 1–8) on the
NI 6584R.
2. Connect the Port 1 DB9 connector from the NI VHDCI-to-Eight DB9 cable to the DUT with
proper termination.
Note
This exercise shows how to complete these tasks for the full duplex version of the NI 6584. To
complete these tasks with a different hardware version of the NI 6584, replace every instance of Full
Duplex in these instructions with Half Duplex, Full Duplex No Termination, or Half Duplex No
Termination, depending on which device you are using.
3. Launch LabVIEW.
4. In the Getting Started window, select Find Examples to display the NI Example Finder.
5. In the NI Example Finder window, select Hardware Input and Output»FlexRIO»IO Modules»
NI 6584.
6. Select NI 6584 Basic Software UART Full Duplex.lvproj.
7. In the Project Explorer window, double-click NI 6584 Basic Serial UART Full Duplex
(Host).vi under My Computer. The host VI opens. This VI uses the NI 7952R as the FPGA target
by default. To use the NI 6584, complete the following steps to change the FPGA target.
Note All example projects are configured for RIO0. If your device is not named RIO0 (verify in
MAX), you must update the target device name by right-clicking your device in the Project
Explorer window, selecting Properties, and entering the correct target device name in the Resource
control.
a. Select Window»Show Block Diagram to open the VI block diagram.
b. On the block diagram, right-click the Open FPGA VI Reference (PXI-7952R) function and
select Configure Open FPGA VI Reference.
c. In the Configure Open FPGA VI Reference window, click the Browse Project button in the
Open VI section.
d. In the Select VI window that opens, expand the tree view for your device, select the VI under
your device and click OK.
