| 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. |
