I am using LIS3MDL sensor and I do not understand the sensitivity which its unit is LSB/Gauss.   In x-cube-mems1 library, the following is calculated:   #define LIS3MDL_MAG_SENSITIVITY_FOR_FS_4G    0.14 /**< Sensitivity value for 4 gauss full scale [mgauss/LSB] */ #define LIS3MDL_MAG_SENSITIVITY_FOR_FS_8G    0.29 /**< Sensitivity value for 8… (Show more)

Hi all,   I connected STEVAL-MKI137V1 (Magnometer sensor) to STM32L152D-EVAL through I2C. The library I am using is from STM32CubeExpansion_MEMS1_V4.0.0.   I connected I2C pins to PB11 and PB10 without any external resistors on STEVAL-MKI137V1 side.   The problem is weird for me. Most of the times the code do not work, it give error like… (Show more)

I'm using MP34DT01 MIC ,but i found that the niose is extremely large. My mcu is STM32F429VGT6,using its I2S peripheral. I use  libPDMFilter_IAR library convert  PDM signal to PCM signal.but there is a large amount of white noise. A group of sample data is in the attachment.(PDM data read from the mic in quiet environment) Is these sample data… (Show more)

Hi Guys, I'm planning on using the LSM9DS1 as a heading sensor on my board, and I was curious about the functionality of some of the pins - I couldn't find any detailed description in the datasheet.   The pin description describes Pins 5,6 (SDO_A/G, SDO_M) as 'I2C least significant bit of the device address' for I2C mode - are these required if… (Show more)

Hello Forum and ST support,   I am using LSM9DS1 IMU sensor, and In the datasheet, they've mentioned that LSM9DS1 Magnetometers are factory calibrated, but when I calculate the heading and I compare it with a compass App I don't get the same value or even an approached one.   I am using a SparkFun LSM9DS1 library which contains a magnetometer… (Show more)

I have recently bought a STM32 Dev board with a X-NUCLEO_IKS012A mems sensor. I am new to embedded software and decided to get one of the example projects going for this board. I have gone through all the readme's etc. but st doesn't specify where to save the example project when downloaded from the internet. I get the following error: make: ***… (Show more)

Hello, I am using VL6180X-SATEL on STM42F4 Discovey Board and download the STSW-IMG003 software. When I implement it in Keil v5.0.0 and try to use vl6180x_simple_ranging.c code, program shows mi 3 errors, that file vl6180x_sample_plat.h in vl6180x_simple_ranging.c cannot be found, and that unist.h and pthread.h cannot be found in… (Show more)

Hi guys,   I'm developing a application that uses a XNUCLEO-6180XA1. The development board is a PSoC-4 enabled board with arduino headers (CY8CKIT-042 PSoC® 4 Pioneer Kit | Cypress Semiconductor ).   I'm using the library provided by ST and I wrote the HAL functions to provide access to the VL6180x module.   At this moment, I can access the… (Show more)

Hello all   I have a problem with setting LIS3DH module to detect movement. To be more precise, I want the device to set the INT1 pin down when the it experiences 32mg acceleration change for 0.5 second.    Here are my settings: CTRL_REG1 = 0x20 //10Hz, normal power mode, ZXY enable CTRL_REG2 = 0x00 //no HP filters CTRL_REG3 = 0x40 //IA1… (Show more)
