Hi,
I think that there is 2 possibilities to do that:
1. use 4 bits of DIO or MIO card's digital IO and program the
whole I2C interface in labVIEW ( or C ). 2 lines for clock and data:
1 for output drive, 1 for line state detection,a series resistor should be
connected between driving dio pin and I2C line.
2. use an external I2C controller such as Philips' PCF8584. you will
need 8 bit databus and a few control signals from PC + clock. The
controller takes care of the I2C bus, and the program has to only
do reads and writes via the 8-bit data bus. If you have other
components on board you can share the data bus.
