Hello Nea,

it would be easier to answer your question, if you could provide use some more information. Which task to you want to accomplish? Which software do you want to use? Which hardware?

Hi there. I recently had the same problem, didn't know how to communicate with an I2C sensor.

Basically, you have to have a master and slave in the system. Then you have to initiate a clock and data. However, I found a beautifully simple solution.

It's a little development board using an NXP chip. You plug it into a serial port and by sending it characters with a simple terminal program you give Hex numbers to it and can read or write registers over the I2C bus. It's then a simple step to program the serial comm in Labview.

Hope this helps.
