The board is equipped with a digital accelerometer sensor module. The ADXL345 is a small, thin,
ultralow power assumption 3-axis accelerometer with high-resolution measurement. Digitalized
output is formatted as 16-bit twos complement and can be accessed using I2C interface. Connected
to the I2C interface includes two peripherals, the G-sensor and the LTC connector. The I2C address
of the G-Sensor device is 0xA6/0xA7. For more detailed information of better using this chip,
please refer to its datasheet which is available on manufacturer’s website or under the Datasheet
folder of the SoCKit System CD.
Figure 3-27
shows the connections between ADXL345 and HPS.
