NI Instruction Sequencer and SPI Example for the NI PXIe-5644/45R » This example uses NI-RFSA and NI-RFSG instrument driver FPGA extensions, along with the instruction sequencer and SPI IP to create FPGA personalities for the NI PXIe-5644R and NI PXIe-5645R that have the ability to issue sequences of SPI commands for hardware-timed DUT control.

Description: This example uses NI-RFSA and NI-RFSG instrument driver FPGA extensions, along with the instruction sequencer and SPI IP to create FPGA personalities for the NI PXIe-5644R and NI PXIe-5645R that have the ability to issue sequences of SPI commands for hardware-timed DUT control. The example shows how to download instruction sequences from the host, configure the SPI IP settings, and then trigger sequence generation for hardware-timed execution. No NI-RFSG or NI- RFSG functionality is demonstrated, but since this FPGA IP is completely asynchronous to the NI-RFSG and NI-RFSG FPGA functionality, the only required order of operations is that the host interacts with the additional IP after an NI-RFSA or NI-RFSG initialization.

Installation Notes:

After installing a VI package containing an instrument driver FPGA extensions host example, before opening any of the host VIs, move the sub-directories installed under the example parent directory into c:\Program Files\National Instruments\NI VST\Custom Bitfiles\ (32-bit Windows) or c:\Program Files (x86)\National Instruments\NI VST\Custom Bitfiles\ (64-bit Windows). The Custom Bitfiles directory may require manual creation, and this process requires administrative privileges. After moving these files, c:\Program Files[ (x86)]\National Instruments\NI VST\Custom Bitfiles\[Sub-directory Name]\Open FPGA Session.vi" should be a valid file path.
