NI Single-Board RIO CLIP Generator Help
»View Product Info
Complete the following steps to use the LabVIEW Interface page of the sbRIO CLIP Generator to create the LabVIEW FPGA I/O Node interface for the NI sbRIO target.
||Note Click the Import from CSV or Export to CSV buttons on the bottom left of this page to import or export LabVIEW I/O node data in a CSV file.
- From the Available Pins control, select one or more pins.
- From the I/O Direction control, select one of the following options:
- Read-only—Creates one read-only I/O item in the LabVIEW project.
- Read/Write—Creates one read-only I/O item and two writable I/O items in the LabVIEW project. The first of these writable I/O items enables the output on the individual pins associated with the I/O item, and the second determines the value being output on the pins. You can read external data on the pins if the output is not enabled.
- From the LabVIEW Data Type control, select the LabVIEW data type to use for the FPGA I/O Node.
||Note If you select fewer pins than the width of the data type (for example, you select 7 pins but specify a U8 data type), the created I/O item uses only the least significant bits. If you select more pins than the width of the data type, the sbRIO CLIP Generator creates multiple I/O items of the same data type.
- Click Add. The LabVIEW I/O Nodes table lists the created I/O node.
- (Optional) Use the LabVIEW Name column in the LabVIEW I/O Nodes table to rename the I/O item. This name appears in the LabVIEW project and on FPGA I/O Nodes on the LabVIEW block diagram. The name must meet the following requirements:
- Cannot be a duplicate of another I/O item name
- Must start with a letter
- Can contain only letters, numbers, and underscores
- (Optional) Expand the information in the Pin Details column to review the details for a created FPGA I/O Node. These details appear in the <clipname>.vhd file for the FPGA I/O Node.
- Repeat the preceding steps to create additional FPGA I/O Nodes for the CLIP. You can drag and drop created FPGA I/O Nodes in the LabVIEW I/O Nodes table.
- Click Next to continue to the Clock Settings page.
