LIS2DW12: SPI data corruption if another device on SPI bus.

With regard to the LIS2DW12 (or other I2C/SPI MEM accel) what stops the I2C seeing SPI traffic when the CS is high and another device on the SPI bus is being clocked. Will the MEM accel try to interpret the SPI data as I2C and end up corrupting the S...

How to read from magnetic sensor?

I use LSM303DLHC. I set the data reading speed for the accelerometer 50 Hz, and for the magnetometer 30 Hz.For the accelerometer, I check in the STATUS_REG_A register (p.28 LSM303DLHC datasheet) the state of the 3rd bit and at the time = 1 I read the...
