: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.
