How does the X-CUBE-MEMS1 Motion MC library know the difference between an LSM9DS1 and an LSM6DSO?

Deep in the STMicro Compass example in the STMicro's X-CUBE-MEMS1 code-package there is a call made to the STMicro Motion MC library to calibrate the LSM6DSO magnetometer. The STMicro compass code passes both the magnetometer values and the accelero...

LSM303AGR Magnetometer weird readout, X, Y axis goes out of the range, Z axis always come with zero

I am using sensor tile to read out the LSM6DSM accelerometers, gyroscope, and LSM303AGR magnetometer data. Accelerometer and gyroscope work well, but magnetometer gives weird output. I set the full scale 50 gauss, the X, Y axis already goes out of th...

How can I read PDM signal from Microphone to DFSDM block using STM32L476G

LSM303AGR Magnetometer result is deviated when iron comes nearby

Hi,we have used LSM303AGR  magnetometer for cupboard Door Open/Close detection and it is working properly.On door close position, i am getting ~0 of every direction as i have done hard iron compensation.Issue i am getting in small cupboard is to open...

I am using IMP34DT05TR sensor and MCU. My circuit configuration is MCU is powered ON and then enable signal comes from MCU power ON sensor. In idle state , MCU is only powered ON and sensor is powered OFF, Here is there any possibility for sensor failure?

[LSM6DSL] Data loss during reading FIFO data?

Hi, I'm testing LSM6DSL FIFO mode. And I have a problem with output data rate.I don't have the problem with reading the data, but my problem is that average data output is about 96.5 samples per seconds while my ODR setting is 104Hz.And here is my qu...

SensorTile.box #NaN: Applications from all over the world

This week the winning ST.box applications of the IEEE International Contest of Sensors & Measurement Systems in Montreal, Canada, have been awarded. 1st prize application: detecting defects in steel sheets using magnetic flux generated by the ST.box ...

Avoiding (seemingly) random STMicro Motion EC Middle Ware bearing output values when the magnetometer's X axis is at a minimum.

Hi, (Was: "I would like to use STMicro Motion MC and EC Middle Ware as a normal compass while the "pitch" is positive 90 degrees.")I would like to use the STMicro Motion MC and EC Middle Ware with an LSM9DS1 sensor while the "pitch" of the LSM0DS1 is...

VL53L1X ToF sensor works fine until I attach another slave device on the I2C bus

I have a VL53L1X ToF sensor working fine (I'm using the VL53L1X-SATEL breakout board). However, when I connect another I2C slave device onto the same bus (its a different type of device and has a different slave address), I see ~60MHz pseudo-sine wav...

Is there anyway to implement to ST Wink to turn on/off at specific times or enter a low power mode to save battery?

STEVAL-STWINKT1I would like to make it the device open for once an hour for 5 minutes and then turn off after that? Is there anyway to implement this feature and how do i do that?
