lmsdso32 spi fifo reading using rounding issue

To make a successful read via the spi bus of the fifo in rouding mode should return 7 bytes, the tag byte plus 3 words but the device does not return correct data or count as a successful fifo (and update the fifo size). What data is returned is rubb...

Incorrect LSM303AGR Accelerometer Data

I'm trying to interface with the LSM303AGR using the 3-wire SPI protocol. I'm polling the registers 0x28 - 0x2D in high-accuracy mode, and what I've noticed is that the least-significant nibble of each axis is occasionally 0x1 instead of 0x0 as expec...
