MEMS (sensors)

Hi,Is it possible to modify the amount of values that are written in the FIFO buffer after a trigger event has occurred in continuous-to-FIFO mode? Currently the device collects values in the FIFO buffer in continuous mode until a trigger event happens after which 32 new values are collected in FIFO and collection is stopped. I would like the device to do the same except only collect 16 new values during FIFO mode, keep 16 values from continuous mode and then stop collection. Is this possible by varying some value or is the buffer wiped when the trigger event occurs?Thank you in advance for answers!

Hello,I want to use the LIS3MDL for a project. I am using a microcontroller with I2C lines at 3V3. In the datasheet there is mentioned that the typical voltage for VDDIO is 1V8 but with a range up to VDD +0.1 V. I will power the device (VDD) with 3V3. If I also use 3V3 for the VDDIO will the sensor communicate at 3V3 or 1V8. Thank you in advance

I have had testing the SensorTile.Box and today I was trying to turn it on to continue testing and dosen't work, leds didn't ligth up and the sensortilebox looks broken. I was trying to reset the sensor (plug in and plug off the battery) and press the power bottom but didn't works.Whether someone could help me pls.

Hi,While trying to calibrate the magnetometer, upon successive failures, I noticed that the values that were read for the Y and Z axes are successively repeated until a different value is read (as can be seen below). It appears that there's some kind of great threshold for a new value to be stored in the register. It's hard to debug this issue, especially since the documentation on the magnetometer of the LSM9DS1 is quite scarce (namely its functionality, as opposed to the accelerometer and gyroscope on the datasheet).The configuration is as follows:int32_t IMU_config(IMU_FW * imu){ /* Check device ID */ lsm9ds1_id_t whoamI; lsm9ds1_dev_id_get(

I can link the MotionMC library in the Nordic project and build it successfully. However, the MotionMC_GetLibVersion function is not assigning the version pointer.

Does the LIS2DE12 have a soft reset ? Data sheet is unclear

I'm currently testing an LSM6DSL Click board in Power-down mode, with both the Accelerometer and Gyroscope in Power-down mode, in order to achieve minimum current consumption.However, I've encountered a problem. When I constantly move the sensor for approximately 1 minute, the current consumption spikes up to around 200uA. On the other hand, when I place the sensor on a flat surface and keep it still, the consumption stabilizes at around 3.9uA, which is consistent with the value provided in the datasheet (3uA).I expected the current consumption of the LSM6DSL to remain the same while in motion as it is when idle. Are there any additional registers that I need to configure apart from CTRL1_XL and CTRL2_G?I would greatly appreciate any assistance!Note: I always reset the LSM6DSL by setting the SW_RESET to "1" via SPI before taking measurements.

Hello, I recently started working with Unico GUI software and I need to do a classification task for soundwaves with already gathered data using the decision tree from the MLC but I would like the classification based on features that can be extracted from the frequency domain (FFT) such as harmonics, spectral slope, pitch, etc. I am working in offline mode and first of all I would also need to compute the FFT of the loaded data but I haven't been able to do this in the Unico software. Is there a way to build the decision tree using features liek these or the only features available are the ones on the MLC (mean, variance, energy, peak to peak, etc.). Does anybody have a solution for this issue?

Hello everyone. I make some project based on MotionMC and MotionEC libs. It's a magnetic compass which will use inside the cars. Within the MotionMC library, the end device functions properly if calibrated according to section 2.2.5 of the UM2192 manual ("figure eight" pattern). My issue is that the compass is firmly fixed inside the car, so it is not possible to calibrate it using the "figure-eight" method :beaming_face_with_smiling_eyes: Is there any alternative calibration method available for the MotionMC library that is suitable for use in a car? For example, rotating the compass in a circle within one plane or manually entering constants? Or is the MotionMC library not suitable for this task, and should I look for an alternative? Regards.

Dear Sir/Madam,​I am trying to configure x axis, y axis and z axis in LIS2DTW12 SENSOR IC interfacing with NUCLEO-L476RG microcontroller when board is towards sky direction. These are the values in z axis1.26 in (+-2g configuration), 2.046 in (+-4g configuration) ,4.125 in (+-8g configuration) and8.254 in (+-16g configuration). Can you conform if the above values are correct?

Hi! My name is Vincenzo.Taking a look at the two sensors, I started to believe that they are similar in terms of Architecture, more precisely it seems to me that the VL53L1 has expanded the characteristics of the VL53L1X at the expense of a slightly lower maximum ranging distance. As I feel that the Ultra Lite version of the API for VL53L1X is very useful, I would like to know if I can use it to manage the VL53L1.Thanks in advance for your supportVincenzo

Hello STMicroelectronics Support Team, I am currently working on a development project where I'm utilizing the LIS2DW12 accelerometer. However, I've encountered an issue with the current consumption of the accelerometer on our custom board. I would appreciate your assistance in resolving this matter.Configuration Used:lis2dw12_block_data_update_set(&dev_ctx1, PROPERTY_ENABLE);lis2dw12_full_scale_set(&dev_ctx1, LIS2DW12_8g);lis2dw12_filter_path_set(&dev_ctx1, LIS2DW12_LPF_ON_OUT);lis2dw12_filter_bandwidth_set(&dev_ctx1, LIS2DW12_ODR_DIV_4);lis2dw12_power_mode_set(&dev_ctx1, LIS2DW12_HIGH_PERFORMANCE);lis2dw12_data_rate_set(&dev_ctx1, LIS2DW12_XL_ODR_25Hz);Issue: After incorporating the LIS2DW12 accelerometer into our custom board, we noticed a current consumption of approximately 1.5 mA. However, upon removing the accelerometer, the current co

Is there a way to move between inactive sample rate and regular sample rate with FSMs enabled?I have configurations written from the host microcontroller to the LSM6DSR in which I can enable or disable double tap and enable or disable the FSM(s) in the configuration. I notice that if I enable double tap but not the FSMs then the sampling moves between low the rate for inactive and the rate for active but if I enable the FSMs at all, then the rate stays at the "active" sampling rate.ODR_XL = 2 (26 Hz)ODR_G = 0 (power-down)INACT_EN = 3 (sets accelerometer ODR to 12.5 Hz (low-power mode), gyro to power-down mode)FSM_ODR = 1 (26 Hz)I'm attaching an example configuration header file, which is a merge of saving FSM config and general config from the unico tool.You can see the sample rate change on a scope (measuring current draw) when the FSM are not enabled. The sample rate never moves from 26 Hz to 12.5 Hz when the FSM is

ST(Semiconductor) chip LSM6DSLTR, the website has NOT checked NRND(NOT RECOMMENDED FOR NEW DESIGNS) notice information, how long is the remaining life cycle of this chip?When is the expected date FOR the manufacturer to notify NRND(NOT RECOMMENDED FOR NEW DESIGNS)?ST official website to check the promise of 10 years of supply, that is to say 10 years after the supply is not guaranteed?

I have several lsm303agr that with the accelerometer and the magnetometer in power-down mode consume between 40uA and 20uA while others consume about 2uA as indicated on the datasheet.Even if they have this higher consumption, they perform the self tests correctly.What could this behavior be caused by?In my board Vdd = VddIO = 3V

Hi,We are using LSM6DSO32 Sensor in our device. For our application we need two things(Should be able to operate in low power),1) Free fall detection (if device falls down, interrupt should be generated)2) Motion detection (if device is in motion/at rest, interrupt should be generated) Current Register setting for Fall detection(Low power) is CTRL1_XL,0x30, CTRL2_G,0x34, CTRL7_G,0x80, WAKE_UP_DUR,0x00, FREE_FALL,0x02, MD1_CFG,0x10, MD2_CFG,0x00, TAP_CFG0,0x01, TAP_CFG2,0x80, CTRL6_C,0x10 We tried Motion Detection as per the Application note (AN5473) configuration,But could not get any interrupts generated. What should be the register setting to get both free fall detection and motion detection in low power conditions.?

I have the source code for the Proteus_BLE_CbM app. No docs to explain how it works either. Any example code would be helpful.Thanks

Hello everyone,I need help regarding LIS3MDL magnetic sensor aka compass issue is i am using this sensoron my custom made gps pcb which is then used by my quadcopter the issue is that it works fine at the very start but after few usage when i connect my drone multiple times it just go dead my quadcopter start to say bad compass health and as soon as i replace the LIS3MDLit again goes back to normal and this is repetitive i have 15 drones and it's happening to all of thembefore this i had used HMC5883 compass never faced any problem but LIS3MDL seems to having some issue i am also attaching the schematic of my compass PLEASE ANY HELP OR ANY INSIGHT WILL BE HELPFUL I AM STUCK HERE FOR MONTHS NOW

Im testing the entry mode and i try the vibration app. I think my accelerometer dosent work because the led is always on (everytime detected a event), how can i check it?

Hi,I'm trying to get the LIS2HH12 accelerometer to work via SPI. The message I'm sending seems correct to me, and all the timings are within the minimum and maximum specifications that I have found in the datasheet. I have tried multiple SPI configurations without much luck. Below is what I get on the my logic analyzer.I have managed to talk to this exact chip on this board via I2C via bodge wires. The SPI driver I'm using is part of TI-RTOS.

I have tried many things to get my pc to recognize the serial port of my sensortilebox, i have windows 10, so i shouldnt have this problems. Some know how to fix it?

Hello!This is what I have done yet:I started by launching STM32CubeMX and creating a new project for my specific STM32 Nucleo board.Once the project was created, I moved to the Pinout & Configuration tab. There, I enabled the I2C1 peripheral. I then set the SDA and SCL pins in accordance with the I2C configuration for my board.Next, I went to the "Software Packs Component Selector" and entered "lis3mdl" into the search bar. This allowed me to locate the lis3mdl component, and I opted for the I2C interface (over SPI) as this is how I plan to communicate with the sensor.Moving to the "Project Manager" tab, I changed the Toolchain / IDE to the one I am using (for example: KEIL or STM32CubeIDE). I also set the firmware package name and the project's location.In the "Advanced Settings" under "Code Generator", I chose "Copy all used library files into the project folder", to ensure all necessary files are available locally.

Estoy probando el SensorTile.box y he intentando reiteradas veces probar alguna de las aplicaciones que ya están diseñadas, he intentado en IOS y se queda cargando el overwrite y nunca termina, y he probado en Andriod y me da un error de Timeout.¿Alguien sabe lo que me está pasando? He probado conectar y desconectar la bateria, intente con varios telefonos y probe apagando y encendiendo la placa

Hello,I have an issue with my STM32G431 MCU communicating with an LSM6DSV16BX sensor via 4-wire SPI. The problem occurs randomly when the device is stationary and mounted securely. The gyroscope provides incorrect measurements consistently, with gy_raw_data[axis_0] always being 8192, gy_raw_data[axis_1] being something normal, and gy_raw_data[axis_3] equal to 704. Similarly, the accelerometer occasionally gives a 1g acceleration in the Y axis instead of the expected Z axis.I have ruled out communication errors through various tests, including the use of a high-end logic analyzer. The inconsistent data from the LSM6DSV16BX sensor occurs randomly.My question is: How can I determine if the sensor is malfunctioning? Can a self-test sequence be used to identify any errors?

The ispu example could be interesting for me. It would be nice to have the source code of the libMotionFT. In general, it would be helpful to publish code without object code.
