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.  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  DE1-SoC  System  CD.

Figure 3-35

shows the connections between

ADXL345 and HPS. The associated pin assignments are listed in

Table 3-34
