Hi,
Regarding your question on the interphase, you can also refer to the links below that has a similar questions with yours.
1. Using I2C or SPI communication with cRIO and NI 9403 Module and Scan Engine - NI Community
2. I2C, SPI, and JTAG Communication with NI Digital I/O Devices - National Instruments
Understanding the I2C Two Wire Bus Interface with NI LabVIEW - NI
I believe there would be some examples which you can refer in link 2.
Best Regards.
