Resolved! What is best PCB material for IIS3DWB accelerometer for industrial condition monitor? Is there any ST recommended guideline for PCB layout and fabrication?

Resolved! I am using BSP_MOTION_SENSOR_GetAxes function to acquire data (gyro+accelero) from sensortile kit. I want to know: 1- What are the output units of this data? 2- Do I need to do any processing before passing this data to MotionDI_update function?

Dear ST Community, I am currently trying to setup a Finite State Machine (FSM) for the LSM6DSO32. Is there somewhere an example?

I'm using the NUCELO-G071RB with the STEVAL-MKI215V1. I tried to use the example code for the LSM6DSO available on github: https://github.com/STMicroelectronics/STMems_Standard_C_drivers/blob/master/lsm6dso_STdC/examples/lsm6dso_fsm.c, since I did no...

Resolved! How do you install the X-CUBE-MEMSMIC1 package? It does not appear in the STM32Cube package manager and trying a local import of the zip file fails. What am I missing?

Resolved! Can anyone please tell me the Device Marking codes for LSM6DSL, LSM6DSO and LSM6DSM.

LIS2DW internal Anti-Aliasing filter 1. what order of filter is Anti-Aliasing filter? what's the cutoff frequency of attenuation band? What is the attenuation in the stopband?what's sample rate of internal ADC?

Backgroud: i'm hardware engineer and work for SKF. we used your Lis2DW in our product to test speed of metro.Issue: we found some noise siganl or high Freq. aliasing add in collected data in low frequency. In LIS2DW user guide manual, i find some dec...

Resolved! How to properly use execution_config.json for STWIN DATALOG1 firmware?

Hi,I need to use the execution_config to enable autonomous mode for my STWIN, and sample intermittently a couple of sensors. So I put at the root of my SDCARD the two json files (DeviceConfig and execution_config) with the following code supposed to ...

[lis2dh12/lis2dw12] INT1 signal too low/no signal output

Hi guys,I am currently working on a project with lis2dw12 tap and orientation interrupt. I have come across an issue of INT1 output.I have tested the INT1 output signal with the code below:#include "lis2dh_reg.h" void lis2dh_int_test(stmdev_ctx_t d...

I have edited the real-time 'DataLog' application provided in STSW-STLKT01_V2.5.0 to include the MotionDI_update function. However, my code hangs after I get the tilt and acceleration values for the first time. How to solve this?

int main(void) { HAL_Init(); /* Configure the System clock to 80 MHz */ SystemClock_Config(); MX_GPIO_Init(); MX_DMA_Init(); MX_CRC_Init(); MX_RTC_Init(); MotionDI_Initialize(&freq); /* Optional: Get version */ //...
