All Implemented Interfaces:

Subsystem

public class Leds
extends SpectrumLEDs

Robot LED subsystem for the 2026 REBUILT season.

Extends SpectrumLEDs to inherit the full pattern library (solid, stripe, blink, breathe, rainbow, chase, bounce, gradient, ombre, wave, countdown, etc.) and the CANdle hardware abstraction. Robot-specific convenience command methods are defined below; bind them via triggers in Robot.java or SuperStructure.

Hardware: CANdle device ID 1 on the CANivore bus, 20-LED RGB external strip at brightness 0.5. LEDs are disabled on signal loss.

Field Details

NUM_LEDS

public static final int NUM_LEDS

Number of external LEDs attached to the CANdle output (indices 8–27 on the device).

• Constant Field Values

ledsConfig

public static final SpectrumLEDs.Config ledsConfig

Static hardware config. Set startIdx = 8 to address only the external strip (skipping the 8 onboard CANdle LEDs); keep at 0 to address all 20 LEDs starting from the first onboard LED.
