FEASA LED ANALYSER
FUNCTIONAL VERSION
Get Data Mode
getRGBI## - Get RGB and Intensity for a LED
Transmit Receive
getrgbi##
getrgbiall
Rrr ggg bbb iiiii
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.
rrr , ggg and bbb are the red , green and blue components of the LED Colour.
These values are normalized and are in the range 0 – 255.
iiiii represents the intensity value of the LED under Fiber xx. This 5-digit number is in the
range 00000 – 99999. 00000 represents no Intensity or under range(i.e. the LED is off) and
99999 will represent over range or the LED is too bright.
Description
This command instructs the LED Analyser to return RGB and Intensity data for fiber ## (01-
20) in format
rrr ggg bbb iiiii where rrr , ggg and bbb are the red , green and blue
components of the Colour. The iiiii value indicates the intensity value.
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 getrgbiall command to read back the LED data for all 20 leds in
one command.
Example:
The PC transmits getrgbi05 to the LED Analyser to instruct it to send the stored Colour and
Intensity data for the LED positioned under Fiber No 5. The LED Analyser will return a string
rrr ggg bbb iiiii to the PC.
