Severe gyro integration error on LSM6DSM

Our application requires extraction of angle from the gyro samples over short periods of time- a few seconds. In other words, we need to integrate the gyros. We see that when we integrate the data when the device is static the accumulated error is fi...

Question regarding SensorTile.box 3rd party integration

Hi, Not sure if this is the right place to ask this but not finding any better options after looking around your website a bit. I have an IoT Hub/Gateway application that provides the ability to build out a lot of typical IoT functionality without...

SensorTile.box error - SD file needed for the app not found

I am trying to upload apps to the tile, but for some of the entry level example apps (e.g. vibration monitor app) and for an expert mode app that I designed I get an error when trying to upload the app. It says: "SD file needed for the app not found"...

I want to chain in SPI several LPS22HB pressure sensors. I would like to realize a daisy chain or a serial SPI chain.

A daisy chain seems to be complicated because i can not configure the SPI chain in 4 wired at power up.Or, I would like to connect a specific CS on each LPS22HB and connect SCL / SDI / SDO together on the same SPI bus of the MCU. But I do not underst...

Resolved! Pressure of sensor LPS22HB always equal to 0.0

I use a STEVAL-IDB008V2 and connect sensor LPS22HB to it. By I2C bus , my program communicate with the sensor and it receve interrupt for end of pressure acquisition. The problem is that the pressure read is always equal to 0.0.

LIS2DE12 FIFO mode

I configured the device and I am able to read XYZ data by polling the status register 0x27 and reading data when it is ready. I read more than 32 samples of each. Then I tried to turn on the FIFO and setup Interrupt 1 for the I1_Overrun. I wasn't ...

I am new to STM 32 MCU, it might be a basic issue I might be facing but couldn't find any solution in the documentations as well. When I am trying to connect STM 32 Nucleo and an IKS01A2 expansion board using a Unicleo GUI I am facing some problem

When I am trying to login to Unicleo GUI I am able connect to the communication port but the firmware description, version, expansion board name and library version in the login screen is showing unknown as I result , i suppose, am not being able to ...
