0005 Description:
0006 Get measured values from the ADC for these stages. Y is the
0007 specific stage number corresponding to datasheet stage names
0008 as follows:
0009
0010 == ==========
0011 1 LED2
0012 2 ALED2/LED3
0013 3 LED1
0014 4 ALED1/LED4
0015 == ==========
0016
0017 Note that channels 5 and 6 represent LED2-ALED2 and LED1-ALED1
0018 respectively which simply helper channels containing the
0019 calculated difference in the value of stage 1 - 2 and 3 - 4.
0020 The values are expressed in 24-bit twos complement.
0021 The LED current for the stage is controlled via
0022 out_currentY_raw.
