LSM9DS1 SDO not tri-stated

I need several LSM9DS1 sensors one the same SPI line. However, I noticed that when CS is high, SDO (aka MISO) is not tri-stated but pulled down to GND.I thought this was due to the default double-interface (SPI/I2C), so I have enabled the I2C_DISABLE...

Resolved! Anomalous acceleration values from some LSM6DSLs: are they damaged?

I've used a number of times LSM6DSL IMU sensors and I never had any problem with them: they are in general very precise and straightforward to use. However, in a recernt pre-production run, some accelerometers provided strange values on one or two ax...

Using LIS3DH with VDD only and using VDD_IO for setup only.

Question is if I can use LIS3DH with VDD only (3.3v) , and VDD_IO (1.8v) supply only during configuration ? And in this case, what power use INT1 and INT2 pins ? If possible to run on VDD only with having them working (at least as OD ?).Datasheet is ...
