I3G4250D: 3-axis digital output gyroscope
|
||
|
#########################################
|

|
|
||
|
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.
