Reading the Temperature of the FPGA on an NI USB R Series Device

You can read the FPGA temperature of an NI USB R Series device. Complete the following steps to read the temperature of the device FPGA.

1. Create a new project or open an existing project.
2. Configure the LabVIEW Project for your NI USB R device by completing the following steps:
   1. Right-click My Computer in the Project Explorer window and select New»Targets and Devices from the shortcut menu to display the Add Targets and Devices dialog box.
   2. Select the appropriate device under R Series and click the OK button.
3. Make sure the FPGA Temperature I/O item is added to the project.
4. Right-click the FPGA target in the Project Explorer window and select New»VI from the shortcut menu to add a new VI to the project.
5. Place an FPGA I/O Node on the block diagram of the VI.
6. Click the element section of the FPGA I/O Node and select Add New FPGA I/O.
7. In the New FPGA I/O dialog box, select Board I/O»FPGA Temperature from the Available Resources list, and click OK.
8. Right-click the FPGA Temperature output of the FPGA I/O Node and select Create»Indicator from the shortcut menu.

The FPGA Temperature output returns fixed-point data from the FPGA in degrees Celsius. The fixed-point data is signed, with a word length of 12 bits and an integer word length of 10 bits.
