 * The following example illustrates how individual tables can be declared, and
 * later assembled into a complete LUT data structure using adi_sense_1000_AssembleLutData().
 * That LUT data structure can then be written to the ADI Sense 1000 device 
 * using adi_sense_1000_SetLutData().

/*
 * The following table provide linearisation data for a 4-wire bridge sensor
 * identified with the ADI_SENSE_1000_ADC_SENSOR_BRIDGE_4WIRE_1_DEF_L2
 * sensor type.  The Look-Up Table provided maps a range of input (X)
 * values to a corresponding range of output (Y) values.  In this example,
 * the bridge sensor input in millivolts is effectively translated to volts.
