How to setup FIFO for LIS2HH12?

I am using LIS2HH12 with Atmel ATSAM4E8C and am able to read registers and write to registers.When I read FIFO_SRC register (0x2F) I get Bit EMPTY=1 and in STATUS register (0x27) ZYXDA is constantly 0. I am following the example from https://github.c...

I'm using a LSM9DS1. I find that the datasheet gives a good functional description of the accelerometer and gyroscope, but it only gives register level information for the magnetometer. Is there a datasheet for the compass as a stand-only part?

The datasheet also refers to self test modes, but no explanations are given.

Is Sound MeteR (SMR) Library GCC executable available in -mfloat-abi=softfp?

Hello,I can't use SMR library in GNU toolchain as only hard fp version is available from ST. I can't use hard flag to compile my application as I have other libraries compiled with soft.Thanks and Regards,Dario

About VL53L1X-SATEL Schematic

Hi,I'm designing a board of VL53L1X.About the schematic of PDF (VL53L1X-SATEL) page 4.(https://www.st.com/resource/en/data_brief/vl53l1x-satel.pdf)According to a datasheet, GND of VL53L1X are 2,3,4,6,12pin.But, 6pin isn't connected with GND by the s...

How to enable PRINTF in the STBOX1 function pack examples?

Hello,I am trying to enable the STBOX1_PRINTF macro in the BLESensors application so I can mess around with the code and see the results. When I uncomment the STBOX1_ENABLE_PRINTF in STBOX1_config.h and rebuild/upload the firmware I can see two new d...

How to use my own board with Unico-GUI

I used the breakout and evaluation board with Unico.Now I want to use my own board with sensor.I want to use Unico to capture, process, display sensor data.I may need to implement the communication protocol via serial port.Do you have some documents ...

How Can I get that software: https://my.st.com/content/my_st_com/en/products/embedded-software/proximity-sensors-software/stsw-img013.html#overview thanks

What is the noise of the accelerometer in g/sqrt(Hz), of the magnetometer in gauss/sqrt(Hz), and the gyro in dps/sqrt(Hz)? The offsets for the gyro and the compass in the data sheet seem unreasonable. Should the units be mdps and mgauss?

How to read MLC features on LSM6DSOX?

Since LSM6DSOX can calculate some statistics on the raw data, like mean and standard deviation I would like to use this capability and read and send this data to the host app on the PC. I do not need any classifier functionality for my use case and j...
