The syntax error:
x raw = should be x_raw =
Long is not needed when x_raw = 65535 - x_raw
better use x_raw = Not x_raw
then no need to remember magic numbers.

Singles are needed, when you calculate angles from x,y, unless you have arctan function using integers.

Yes,
x_raw.hb = b(0) is ok

Hi,
I'm getting good results (I think) There's no calculation yet, I think the results are in radians.
I'm getting a problem where I get switching between sensible readings, to all zeros. I've tried SPICLOCK_STRETCH, which may be making a difference, but not curing it. Can anyone shed light on this please?

See attached, two 5110 images, showing XZY registers +B register + mode settings.

EDIT: I've also tried disabling the OSCTUNE.PLLEN = 1 '*4 PLL enabled so Fosc = 32MHZ, but no difference.
Also, tried, 'when showing all zeros' switching off/on and reprogramming, but it still shows zeros.

I have a LED flash which shows the MAIN LOOP is being looped.
C.

The results are not radians, they are the x,y components of the magnetic field.
You get the angles with arctan function from x and y, see the other thread.
