23 Description:
24 The sensor is able to perform
25 measurements due to changing t
26 light conditions. It can be pr
27 a second order error polynomia
28
29 Phase data has to be collected
30 ambient light are modulated in
31
32 Then a least squares curve fit
33 polynomial has to be generated
34 resultant curves have the form
35
36 From those two curves, a and b
37 stored in in_proximity0_calib_
38 in_proximity0_calib_phase_temp
39 in in_proximity0_calib_phase_l
40 in_proximity0_calib_phase_ligh

42 Those values must be integer i

44 Finally, the c constant is set
45 internally.
