I see from various discussions on Cheif Delphi and my personal experience that teams are having a hard time talking to the I2C accelerometer that was included in the 2010 KOP. There was also no supporting documentation for it in the material I downloaded. Using the data sheet from Analog Devices and some mods to the code from the compass class in the WPI library I thought we had a solution but no luck. Is there anything we should know about as far as the NI implementation of a I2C driver or the WPI I2C Class that isn't obvious?Has anyone got it working? Did the compass code from last year ever work? There are so many layers of abstraction in the WPI library that is a real head ache to try to track down anything.At this point I am only interested in C or C++ solutions and not a running commentary on the pros and cons of using LabVIew vs C/C++.Thanks in advance and Good luck programmers and mentors.Brian

C/C++ I2C implementation on the cRio

Hello there,i have problem to read a sensor using in Labview FPGA ( I2C implementation on cRIO 9076 with DI 9402 ). Basically i want to read sensor which would be connected NI 9402 in cRIO 9076 chasis, using Labview program , where the Labview program use I2C bus protocol.

Can anyone give me idea or similar program/instruction ?

thank you.
