Hi,

The BMI08x-Sensor-API and this post might help you.

Hi,

There is a Getting Started guide available in the SDK documentation. If you want to use SPI, we have SPI examples available in the SDK, which can be used as a starting-point, but there are no sensor drivers for BMI085. You need to read the datasheet and find the correct commands to control the sensors. Some manufacturers provide sensor drivers that you can use with their sensors, but you typically need to write the interface to the serial peripheral yourself.

Take a look at SPI Master Example (located in <InstallFolder>\examples\peripheral\spi) and SPI Slave Example (located in <InstallFolder>\examples\peripheral\spis) about how they interact.
