7Description
8***********
9
10This sample application configures the gyroscope with a fixed
11sampling rate and polls the measurements with the same rate and
12displays the measurements along with a timestamp since startup.

14Requirements
15************
16
17This sample application uses the I3G4250D sensor connected via
18SPI interface. This is the case for example for stm32f3_disco@E
19board devicetree.

21Building and Running
22********************
23
24To build the application a board with I3G4250D on SPI interface
25has to be chosen, or a custom devicetree overlay has to be provided.
26Here STM32F3 discovery board is used.
