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....

IIS3DWB acceleration sensor data is strange

y-axisz-axisI am using IIS3DWB to collect the vibration data. When the chip is stationary, the z-axis should be affected by gravity and output 1g, but. But the actual data is that 1g data will often appear on the y-axis data, and the z-axis will bec...

LSM6DSO bulk read

Hi,I've configured the LSM6DSO with an NRF52. The NRF52 is able to use DMA and to trigger the SPI clock for bulk read in background without incorporating the CPU. But as far as I can see in the datasheet and the example drivers the LSM is not capable...

I have purchased STEVAL-MKI109V3 kit. And I'm using UNICO software. However, after installing UNICO software, I'm not able to connect the motherboard (MKI109V3) using USB I followed this youtube link: https://www.youtube.com/watch?v=96GOlBPP0pA

LSM6DSM gravity calculation

Hi,I am testing the accelerometer and can see that it also measures the acceleration caused by gravity.Is there a setting or way to filter gravity out from the reading?If there is any calculation, could you please share us the same for with gravity a...

In all examples from Hands-on Workshop "Developing with Sensors Made Simple"(pdf) the blue button interrupt is forgotten? Especially in LAB 5?

When I press the blue button, the example applications die :( (especially in LAB 5 where blue is a single or double click switch)

IIS2DH INT1 activation for 6D/4D recognition

Hello dear ST community,How can I get activated INT1 for 6D/4D recognition in IIS2DH?I looked in the datasheet for some information but I couldn't find anything.In these design tips for LIS2DW12/LIS2DH12 the 6D interruption is routed in register CTRL...

LSM6DSO gyro outputs when SensorTile.Box module stationary

Hello,I'm in the evaluation stage of LSM6DSO sensor. I've got a SensorTile.Box module and running DataLogExtended.bin firmware and I use Unicleo-GUI to read sensors' data. I'm expecting to get 0 values for the gyro outputs if the module is stationary...
