I need to get acceleration data out of four digital accelerometers ADXL 345 http://www.analog.co.../ADXL345-EP.pdf

I have a LABJACK U3. I need the final data on my PC in form of Time v/s Acceleration ( different accelerometers on different channels)

How do I do it ?

Looks like the chip supports SPI or I2C. I would suggest you try SPI first, as that is a simpler protocol. If you are not familiar about SPI in general, start by reading about it:

http://en.wikipedia....l_Interface_Bus

Then look at the ADXL345 datasheet to figure out what bytes you need to write and read to do what you want.

The look at how to do SPI with the U3:
