6Description
7***********
8
9This sample application configures the gyroscope with a fixed
10sampling rate and polls the measurements with the same rate and
11displays the measurements along with a timestamp since startup.

13Requirements
14************
15
16This sample application uses the I3G4250D sensor connected via
17SPI interface. This is the case for example for stm32f3_disco@E
18board devicetree.

20Building and Running
21********************
22
23To build the application a board with I3G4250D on SPI interface
24has to be chosen, or a custom devicetree overlay has to be provided.
25Here STM32F3 discovery board is used.
