Program Commands
While the ColorPAL is in Buffering mode, you can enter the commands that actually do something, like
light up the LEDs or take a color sample. Here are the commands that it can accept.
— LED Commands —
WARNING! The light from the RGB LED is very concentrated and can be very bright. Just as you would
not stare at the sun (and for the same reason), do not stare directly at the LED.
rnnnnnn
Display RGB Color on LED
A lowercase r followed by six hex digits will cause the LED to display the selected color components, with
00 being fully “off”, FF being fully “on”, and numbers in between representing various intermediate
intensities. To display the color orange, for example, you can send the following command:
SEROUT sio, baud, ["= rC04000 !"]
This causes the red LED segment to light up at 75% intensity (C0) and the green segment to light at
25% intensity (40). The blue segment remains “off” (00).
A - Z
Display Named Color on LED
The uppercase letters represent predefined color names. These are, in order by hue (with letter
designators in boldface, along with their hexadecimal equivalents):
