How to implement SPI in LabView for ADS1675 to communicate with NI FPGA

Hi all,

i have modified ads1675ref board to realize a PWB that makes available communications lines to IO digital lines of a National Instruments single board RIO.

I pulled out following ADS1675 pins available to my national instruments FPGA board:

1. FPGA CLK
2. DRDY
3. /DRDY
4. DOUT
5. /DOUT
6. SCLK
7. /SCLK
8. CLK_SEL
9. LVDS
10. LL_CFG
11. /CS
12. FPATH
13. DR0
14. DR1
15. DR2
16. START

Now I have to write LabView FPGA and HOST code to implement SPI communication with ADS 1675 ADC so i can read data acquired from that.

I know that there is ADCPro Software with which is possible to control ADS1675REF board with EVM Plugins but here the communication to the PC is performed through usb and addressed to and from Opal Kelly FPGA. I just don't know if Opal Kelly FPGA is programmed with LabView or with VHDL language.

In my case i have to implement SPI communication  ADS1675 ADC <-->National Instruments FPGA so i'd like to ask if you already have available labview code for this purpose or, if i've missed something in my reasoning 'till now, EVM ADS1675REF Plugin Labview code can be already useful to this task.

Thanks and Regards.
