.. zephyr:code-sample:: i3g4250d
:name: I3G4250D 3-axis gyroscope sensor
:relevant-api: sensor_interface
Get gyroscope data from an I3G4250D sensor.
Description
***********
This sample application configures the gyroscope with a fixed
sampling rate and polls the measurements with the same rate and
displays the measurements along with a timestamp since startup.
Requirements
************
This sample application uses the I3G4250D sensor connected via
SPI interface. This is the case for example for stm32f3_disco@E
board devicetree.
Building and Running
********************
To build the application a board with I3G4250D on SPI interface
has to be chosen, or a custom devicetree overlay has to be provided.
Here STM32F3 discovery board is used.
