The I2C library takes the 8-bit version of the address (i.e. 0x3A). It does automatically set the R/W bit.

The easiest approach would be to port the LabVIEW example called "ADXL345 I2C Accelerometer".

I am still new to this environment that FIRST has set up for us so please excuse my ingnorance....Where do I find the labview example for I2C. Right now I am set up to write C++ code using the WPI library and the windriver tools..I have no experience with labview..not even sure I have it installed..

Naturally you need LabVIEW installed. Just run it from the start menu and in the getting started window that pops up on the bottom right there is a short list of examples... click on more examples and look for ADXL345 I2C Accelerometer.
