can labview be used to listen spi communication between other devices
You may go for NI USB-8451 card. Logging rate will be limited due to USB communication. Faster rates can be achieved by SPI implementation in FPGA DIO cards.
You got a multi function FPGA card.
Here you have to implement SPI protocol on DIO lines of FPGA card. Make sure your SPI implementation is optimized to use the DAQ functionality(You just got 1Million gates for your FPGA card.)
You should install Labview RT and FPGA with PCI -7830 drivers.
NI R Series Multifunction RIO User Manual.
can the slave VI be used to for the purpose?
You seems correct as Read(F) case of FPGA SPI Slave.vi(from attached zip project) performs a read operation as per SPI shift register length and SCLK. You may implement the same for reading MOSI and MISO data between both the controllers.2 Parallel independent FPGA threads for reading Master and Slave should make it easy for you.
I would suggest you to implement an intermediate buffer(separate 1D array for MISO and MOSI) between logging application and FPGA application to sync high speed acquisiton and low speed logging.
Never used Beagle though good to have a third party bus analyzers to verify your acquired data . I would really appreciate if you let us know the progress :)...
The maximum supported clock rate of PCI-7830 is 40 Mhz. Please make sure your SCLK comes under this frequency (Typical SCLK values can go upto 70 MHz) .
