5# Simple Example for the Qwiic ADXL313 DeviceSet range of the sensor to 2G.
6# Then read values of x/y/z axis of the ADXL313 (via I2C), print them to terminal.
7# Note, other range options are: 0.5G, 1G[defaut], 2G or 4 G.
8# Except for custom range, this example uses default configuration (full resolution, 100Hz datarate).
