Status LEDs

PhotonVision has support for multiple kinds of status LEDs. Make sure you reference the correct table for the type present on your hardware.

RGB LED

Color	Flashing	Preview	Status
Green	Yes	[{{ led }}]{.green}	Running normally, no targets visible
Blue	No	[{{ led }}]{.solid .blue}	Running normally, targets visible
Yellow	Yes	[{{ led }}]{.yellow}	NT Disconnected, no targets visible
Blue	Yes	[{{ led }}]{.blue}	NT Disconnected, targets visible
Red	Yes	[{{ led }}]{.red}	Initializing or faulted, not running
Off	No	[{{ led }}]{.off}	No power or initialization fault, not running

Green and Yellow LEDs

Used on Limelight 1, 2, 2+, 3, 3G, and 3A

Green and Yellow LED patterns may be active at the same time

Color	Pattern	Preview	Status
Green	Slow Flashing	[{{ led }}]{.green} [{{ led }}]{.off}	No targets visible
Green	Quick Flashing	[{{ led }}]{.fast .green} [{{ led }}]{.off}	Targets visible
Yellow	Flashing	[{{ led }}]{.off} [{{ led }}]{.yellow}	NT Disconnected
Yellow	Solid	[{{ led }}]{.off} [{{ led }}]{.solid .yellow}	NT Connected
Both	Alternating	[{{ led }}]{.green .error} [{{ led }}]{.anti-yellow .error}	Initializing or faulted, not running
Both	Off	[{{ led }}]{.off} [{{ led }}]{.off}	No power or initialization fault, not running
