Description:
|
|
Get measured values from the ADC for these stages. Y is the
|
|
specific stage number corresponding to datasheet stage names
|
|
as follows:
|
|
|
|
== ==========
|
|
1 LED2
|
|
2 ALED2/LED3
|
|
3 LED1
|
|
4 ALED1/LED4
|
|
== ==========
|
|
|
|
Note that channels 5 and 6 represent LED2-ALED2 and LED1-ALED1
|
|
respectively which simply helper channels containing the
|
|
calculated difference in the value of stage 1 - 2 and 3 - 4.
|
|
The values are expressed in 24-bit twos complement.
|
|
The LED current for the stage is controlled via
|
|
out_currentY_raw.
