Resolved! LSM6DSV FSM example with baro (LPS22XX) as external sensor?

I have examined the FSM example folder on github and, while there is an example for an external magnetometer, I haven't found any examples for an external barometer. Is there such an example? And if so, where can I find it?I believe I can create my o...

Resolved! reading zeroes from IIS3DWB FIFO

Sometimes, I am reading zeroes from IIS3DWB FIFO. I thought maybe it is because I am using a protoboard (using MKI208) so I connected it directly (with cables) to RPi 4 but it still happens.I guess it is not normal to find these in FIFO, can it be du...

Resolved! asm330lhhx scale factor for each x, y, z axis

Hello,For the asm330lhhx device, when does the scale value change and get set?  I am trying to determine if the scale factor needs to be checked only once at power up or continually while reading the raw x, y, and z values for both the gyro and the a...

Resolved! LSM6DSV Sensor Hub current consumption?

Based on power measurements I infer that using the LSM6DSV embedded SensorHub with a single slave (LPS22DF) costs ~6.4 uA. I can't find the expected current consumption for the LSM6DSV Sensor Hub in the data sheet or application notes. Is this a reas...

Resolved! LIS2DUX12 not reaching current consumption said in datasheet

Hello,I'm evaluating the LIS2DUX12 accelerometer by using the combination of STEVAL-MKI109V3 and STEVAL-MKI238A. In the datasheet it stablishes that it can reach down to 10 nA during deep power-down:But when I measure the current consumption through ...

Resolved! Can't get to find how to turn off temp sensor from LIS2DUX12

Hello! I'm evaluating the LIS2DUX12 accelerometer by using the combination of STEVAL-MKI109V3 and STEVAL-MKI238A. In the datasheet it stablishes that in order to achieve certain current consumption is necessary to have the Temperature sensor off:But ...

Resolved! LIS3DSH, SDO Pullup Register

Hello,We have been using the LIS3DH for some time and recently acquire some LIS3DSH' as well.With both modules there is an internal pull-up for the SDO pin, and with the LIS3DH there is a register to control this pullup:CTRL_REG0I am not able to find...

Resolved! FSM compatibility with SFLP or tap detect in LSM6DSV?

I have four FSM programs working with the LSM6DSV sensor, all set to AODR/GODR of 30Hz in line with the examples I copied. Tap detect requires significantly higher ODR.  I might also want to run the SFLP at a rate higher than 15 or 30 Hz, so does thi...

LIS3MDL hard iron offset registers

 Hi, the datasheet for the LIS3ML does not mention any dedicated offset registers that can be used to deduct an offset vector from the measurements: However, when I view the LIS3MDL app note, it says they are there: The app note points to 05h through...
