To use traditional LabVIEW FPGA programming to develop the FPGA VI, all resources used by the FPGA VI must be added to the project. Complete the following steps to add FPGA I/O, a DMA FIFO, and an FPGA base clock resource.
  1. Right-click FPGA Target in the Project Explorer window and select New » FPGA I/O.
    The New FPGA I/O dialog box appears and displays the I/O resources available on the NI 5641.
  2. In the New FPGA I/O dialog box, expand Analog Input.
  3. Select ADC_0_Port_A_I and ADC_0_Port_A_Q.
  4. Click the right arrow to add these resources to the New FPGA I/O table.
  5. Click OK.
    The FPGA I/O items you configured appear in the Project Explorer window in a folder below the FPGA target.
  6. Right-click the FPGA target in the Project Explorer window and select New » FIFO.
    This FIFO transfers the acquired data to the host computer.
  7. In the FPGA FIFO Properties dialog box, select the General category.
  8. Set Type to Target to Host – DMA.
  9. Set Requested Number of Elements to 32767 .
  10. In the FPGA FIFO Properties dialog box, select the Data Type category.
  11. Set Data Type to U32.
  12. Click OK.
  13. Right-click the FPGA target in the Project Explorer window and select New » FPGA Base Clock.
  14. In the FPGA Base Clock Properties dialog box, set Resource to ADC_0_Port_A_Clk.
    The ADC_0_Port_A_Clk ticks every time the ADC has a new I/Q sample.
  15. Click OK.
