Setting Primary Color Coordinates
Three parameters are defined for each of the three LEDs. These nine parameters are defined in the
header file LED_Calibration.h. The three parameters, in the order they are defined, are maxi-
mum lumens, CIE X base color coordinate and CIE Y base color coordinate. The maximum lumens
designates the maximum light output for the given LED. This value is a positive integer with the
range 8 to 1,856. The X and Y coordinates are the CIE 1931 standard coordinates that designate the
color of light generated by the LED. The settings are defined for the three LEDs assuming primary
LED colors of ‘red,’ ‘green’ and ‘blue,’ although any three LED colors could be used, depending upon
the desired color gamut. Coordinate values are represented as four-digit integers that are interpreted
as four-digit fixed-point fractional values ranging from 0.0000 to 0.9999 in both the X and Y dimen-
sion. Thus, for example, the fractional X value of 0.7011 is defined with the integer value 7011.

DESCRIPTION: Contains all of the defines that are required in
for defined labels in the main program. This is compatible with
firmware that uses fixed-point math instead of floating point math.
This necessitates all of the defines in this file to integers
rather than decimal numbers.
Update 1.2: Removed unused defines and product-specific
parameters.
