import time

# Import the ADXL345 module.
import Adafruit_ADXL345


# Create an ADXL345 instance.
accel = Adafruit_ADXL345.ADXL345()

# Alternatively you can specify the device address and I2C bus with parameters:
#accel = Adafruit_ADXL345.ADXL345(address=0x54, busnum=2)

# You can optionally change the range to one of:
#  - ADXL345_RANGE_2_G   = +/-2G (default)
#  - ADXL345_RANGE_4_G   = +/-4G
#  - ADXL345_RANGE_8_G   = +/-8G
#  - ADXL345_RANGE_16_G  = +/-16G
# For example to set to +/- 16G:
#accel.set_range(Adafruit_ADXL345.ADXL345_RANGE_16_G)

# Or change the data rate to one of:
#  - ADXL345_DATARATE_0_10_HZ = 0.1 hz
#  - ADXL345_DATARATE_0_20_HZ = 0.2 hz
#  - ADXL345_DATARATE_0_39_HZ = 0.39 hz
#  - ADXL345_DATARATE_0_78_HZ = 0.78 hz
#  - ADXL345_DATARATE_1_56_HZ = 1.56 hz
#  - ADXL345_DATARATE_3_13_HZ = 3.13 hz
#  - ADXL345_DATARATE_6_25HZ  = 6.25 hz
#  - ADXL345_DATARATE_12_5_HZ = 12.5 hz
#  - ADXL345_DATARATE_25_HZ   = 25 hz
#  - ADXL345_DATARATE_50_HZ   = 50 hz
#  - ADXL345_DATARATE_100_HZ  = 100 hz (default)
#  - ADXL345_DATARATE_200_HZ  = 200 hz
#  - ADXL345_DATARATE_400_HZ  = 400 hz
#  - ADXL345_DATARATE_800_HZ  = 800 hz
#  - ADXL345_DATARATE_1600_HZ = 1600 hz
#  - ADXL345_DATARATE_3200_HZ = 3200 hz
# For example to set to 6.25 hz:
#accel.set_data_rate(Adafruit_ADXL345.ADXL345_DATARATE_6_25HZ)
