Thanks Nathan. i tried it but i still cannot read sensor output. there is no error from writing on the power_ctl register though

Where does the error actually occur?

[malik1987]

I couldnt find time to work on it last week and now i hooked it up and tried to run it but error 5003 from I2C init. i changed the baud rate to 9600 and the same error still occures.

Just as an FYI, my library can be equivalent to the working examples shown toward the end of the thread but I've yet to get any confirmation on people getting them to work unfortunately.

Nathan, thanks. your library helped alot

i used your library as above and it worked thanks alot

That is great to hear that you were able to get it working.  Is there something specific that you did to get it to work without errors?  Is there a particular reason you didn't use my VI for writing to a register or use the device address and register address as shown in my example? (just wanting to make sure there aren't issues with those parts).

Hi again, i am trying to understand your library.I have a question, why the input of data byte is 6?
