Hi, 

I am new to LSM6DS3 inertial module, I am trying to use it with my arduino mega 2560, in SPI mode ,but in trouble with  Z & Y axis output of the accelero meter. X axis output respond well.

Already tried to read the output raw registers with and without reading the STATUS Register, but the result remains same.  I bought the breakout board from Sparkfun and made necessary changes for using this in SPI mode. Attaching my arduino code with this post.

Which values did you get from Y and Z axis?

I would suggest to set BDU bit in CTRL3_C to 1, to have aligned high and low part of data registers.

I see you are reading the X value twice. Is it intentional?

Changed the value in CTRL3_C to 0x41  , attaching the images of output values of x,y,z of accelero  , all axis are tested with +1g, x gives perfect output, z and y gives some valid output when i give some knock on the table where sensor board is placed.
