RGB Unit Layout
The On/Off Button
The CY3265-RGB evaluation hardware has two buttons and a liquid crystal display. These allow the
unit to be demonstrated without using a personal computer to control the unit. When held properly
for use, the liquid crystal display is on the top right. When held in this orientation, the right-most but-
ton alternately turns the high brightness LEDs on and off. The default setting when first applying
power to the unit is ON; pressing this right-most button illuminates the LEDs.
The Color Selection Button
When the unit is held as described in the previous section, the left-most button along the bottom
edge cycles between seven preset colors. The initial color is white (all three LEDs are illuminated at
high intensity). Pressing this button changes to the next color of the seven preset colors. The color
sequence cycles through white, red, green, blue, yellow, magenta and cyan.
Note If the unit has been controlled from a personal computer using the USB interface, the color dis-
played upon powering the unit and pressing the On/Off button is the last color setting selected when
using the monitor application. The unit displays ‘white’ even though it has never been connected to a
personal computer, or the last color selected could not be displayed at the selected intensity, the
LEDs do not illuminate (an impossible color and intensity combination has been selected). Pressing
the color selection button, selects a valid color for display from the seven preset colors and the LEDs
illuminate with that color.
The Liquid Crystal Display
The liquid crystal display displays the currently selected color using CIE 1931 color coordinates. The
values displayed represent the CIE x, y coordinates for the currently selected color, whether chosen
from the seven preset colors or selected from the Intelligent Lighting Control application (when using
the factory installed firmware).
If the LEDs are illuminated, an asterisk (‘*’) is displayed on the left end of the top row of the liquid
crystal display (this is useful if the last color selected cannot be displayed with the given LEDs,
resulting in the LEDs being dark).
