FEASA LED ANALYSER
FUNCTIONAL VERSION
Get Data Mode
getUV## - Return the u'v' Chromaticity values
Transmit Receive
getuv##
getuvall
0.uuuu 0.vvvv
Where:
## represents the Fiber Number and is a number in the range 01 – 20.
all represents the 20 Fibers in a Feasa 20F, or 3 Fibers in a 3F.
0.uuuu represents the u Chromaticity value
0.vvvv represents the v Chromaticity value
Description
This command is used to return the u'v' 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 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 uv data for the
LED positioned under Fiber No 1. The LED Analyser will return a string 0.uuuu 0.vvvv to the
PC.
