getUV## - Return the u'v' Chromaticity values

getuv##
getuvall
0.uuuu 0.vvvv
Where:
## represents the Fiber Number and is a number in the range 01 – 20.
0.uuuu represents the u Chromaticity value
0.vvvv represents the v Chromaticity value
Description
This command is used to return the uv Chromaticity value for the LED under the Fiber number
##. This command is used for testing White LED's.
The u'v' values are derived from the xy Chromaticity co-ordinates including any xy offsets that
may be applied.
This command should be preceded by a capture command to ensure valid LED data is stored
in the memory of the LED Analyser. The data for each LED can only be read out one-at-the-
time, in any order. Note: it is important for the PC to use 01, 02, 03, etc to indicate Fibers 1,
2 and 3, etc.
Alternatively use the getuvall command to read back the LED data for all 20 leds in
one command.
Example:
The PC transmits getuv01 to the LED Analyser to instruct it to send the stored xy
Chromaticity data for the LED positioned under Fiber No 1. The LED Analyser will return a
string 0.uuuu 0.vvvv to the PC.
