I3G4250D 3-axis gyroscope 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.
