MEMS (sensors)

In MotionFX Library, which is the difference between Heading and Yaw?

The MotionFX library provide me quaternion and rotation angles (roll pitch and yaw). It is possible to obtain the accuracy for these data from the Library?

Hi, I'm using a board which embeds two ST MEMS: ism330dhcx and lis3mdl. I'm exploiting the MotionFX Library to obtain quaternion and rotation. Which is the way to obtain accuracy regarding roll pitch and yaw. I want to understand how close is the val...

Failed to access LIS2DH12 motion sensor WHO_AM_I register via MCU STM32F412CEUx (UFQFPN48).

PB3 and PB10 are enabled as I2C2_SDA and I2C2_SCL to connect to LIS2DH12 SDA and SCL, the i2c2 code is generated in STM32CubeIDE v1.6.1.PB3 and PB10 have pull-up resistors.LIS2DH12 CS and SD0 are connected to Power Supply 3.3V. The address for it is ...

problem with input Raw data

HI I am using STEVAL-MKI182v2 sensor connected to Nucleo-F446ZE Evaluation board and printing the data and found that there is no any changes between i/p and o/p data even after using the library functions and so i started debugging step by step in t...

Customization of ATT_MTU on the SensorTile.box

Hello, I'm currently using a ST SensorTile.box STEVAL-MKSBOX1V1 in Expert Mode (by writing the firmware with the STM32CubeIDE).I configured the SensorTile.box to "publish" data on 3 GATT Characteristics that are quite big (around 180 byte), with the...

Im using LIS2HH12 accelerometer . Im writing the CTRL1 register value as 0x0 then im reading correct acceleration XYZ values. if i write 0x7 value to CTRL1 then im reading XYZ values as 0x0. I don't know what wrong im doing

if i set CTRL1 = 0x0X_H=0x00X_L=0x57Y_H=0x00Y_L=0x5EZ_H=0x3FZ_L=0x33if i set CTRL1 = 0x7X_H=0x00X_L=0x00Y_H=0x00Y_L=0x00Z_H=0x00Z_L=0x00

Problems to pair SensorTile.box to ST BLESensor Application. Basically it scans for nearby boards and then gives an error loading the App. What can I do?

Reading a MKI109V3 with a MKI210V2K module using C# from a console program.

If I deploy this accelerometer into the field, say a long way from anyone it needs to be a simple start on reboot of the computer. UNICO GUI and LITE are not easy reboots. UNICO GUI does not provide a time stamp on records nor a record count, so one ...

accelerometer LIS2DH12 strange and wrong behavior on SPI BUS (I2C is okay)

I have an accelerometer LIS2DH12 connected to my STM32 with I2C and it works fine. Now I changed to SPI bus and somehow the accelerometer behaves strange. I can set parameters like "full scale to 2g" and "set Output Data Rate to 1Hz" and also read ou...

ST BLE Android app not allowing files to be selected to setup AWS connection

I'm trying to connect to AWS for cloud logging but in the android app during setup I select "select file" and it's allowing me to look for the file but when I select a specific file for the certificate or key the app doesn't register that selection....
