MotionFD and SensorTile compatibility

[DIM]

Hello ST Community,

I would like to ask if the (1)SensorTile and/or (2)SensorTile.box are compatible with the MotionFD library?

According to the MotionFD user manual, the library uses Accelerometer and Pressure Sensor data to detect a fall, which both the SensorTile and SensorTile.box contain.

Thank you for your help!

HI @DIM​ , the free-fall detection is available in STBLESensor (Sensortile) smartphone application, so you can detect the free-fall of the board with the standard Sensortile app.

However, if you want to go deeper and modify the FW, you have to be careful to FW/HW level compatibility between the native app of the MotionFD and the Sensortile platform. The X-CUBE-MEMS1 expansion package functionality depends mostly on the microcontroller and the sensors shared by the different HW platform. The MotionFD library matches the NUCLEO-L476RG, which is the MCU of the SensorTiles. LSM303AGR sensor, which is the one dedicated to MotionFD, is compatible between X-NUCLEO-IKS01A2 and SensorTile, so also the sensor compatibility is ok. However, you should take care to the low level SPI/I2C pin definition inside the FW, to be sure to make them 1-1 compatible. After that, you can run the MotionFD on SensorTile. Regards.
