aktk 0:e85788b14028 2 * TRP105F_Spline.h,.cpp
aktk 0:e85788b14028 3 *
aktk 0:e85788b14028 4 * - This library is for provide a distance from TRP105F, proximity sensor,
aktk 0:e85788b14028 5 * to whatever reflect the flash.
aktk 0:e85788b14028 6 * - Deistance is derived from a voltage signal of TRP105F.
aktk 0:e85788b14028 7 * - An object of TRPFS class has an array of sets of
aktk 0:e85788b14028 8 * distance(16 bit-value) and voltage(16bit-value) at the distance.
aktk 0:e85788b14028 9 * - The range of distances that an array has in sets is [0:1024] by 1.
aktk 0:e85788b14028 10 * - an array is derived from a spline curve model.
aktk 0:e85788b14028 11 * - In order to derive spline curve, some value sets should be got
aktk 0:e85788b14028 12 * at the first calibration.
aktk 0:e85788b14028 13 *
aktk 0:e85788b14028 14 * LOG:
aktk 0:e85788b14028 15 * ver.1 2015/10/19 - 2015/10/22
aktk 0:e85788b14028 16 * ver.2 2015/10/22 -
aktk 0:e85788b14028 17 * Distance data type has become unsigned short from int.
aktk 0:e85788b14028 18 * Distance data range : [2:20] by 1 -> [0:1024] by 1.
aktk 0:e85788b14028 19 * ver.2.1 2016/02.12 -
aktk 1:2053662b1167 20 * Distance data range : [0:1024] -> [0:255].
