nRF51822 accelerometer

I'm working on nFR51822 Soc and I wanna use the accelerometer data . Does any one have an idea how to communicate with nRF51822 accelerometer ?

In the schematic it's written LIS3DSh , but i didn't find any useful information about it .

If you google LIS3DSH, the first result points to the datasheet: www.st.com/.../DM00040962.pdf

In chapter 6 in that datasheet the interfaces are described (SPI and I2C).

The nRF51 supports both SPI and I2C. If you download the SDK we have an example on how to use the SPI: developer.nordicsemi.com/.../a00046.html

The SPI driver is documented here: developer.nordicsemi.com/.../a00011.html

And the TWI driver is documented here: developer.nordicsemi.com/.../a00014.html
