Class DotStarsLEDStrip

java.lang.Object

org.usfirst.frc.team1736.lib.LEDs.DotStarsLEDStrip

All Implemented Interfaces:

CasseroleLEDInterface

public class DotStarsLEDStrip
extends java.lang.Object
implements CasseroleLEDInterface

DESCRIPTION:
Driver for Adafruit APA102 DotStar LED strips. Maintains an internal buffer of all LED data, and periodically sends it off to the data over the SPI bus. It is currently configured to utilize the MXP SPI port (not the primary one on labeled the RIO). This will be made configurable in the future.
Datasheet - https://www.adafruit.com/datasheets/APA102.pdf

USAGE:

1. Instantiate Class, with number of LEDS in strip. This will start periodic updates to the LED's in the background
2. Call color classes to change led colors. Changes are automatically pushed out to the strip.

Constructor Detail

DotStarsLEDStrip

public DotStarsLEDStrip(int numLEDs)

Constructor for led strip class

Parameters:

numLEDs - number of LED's in the total strip.

Method Detail

clearColorBuffer

public void clearColorBuffer()

Clears all contents in the color buffer. This turns off all LED's. Be sure to call the updateColors() class some time after this one to actually send the commanded colors to the actual strip.

Specified by:

clearColorBuffer in interface CasseroleLEDInterface

setLEDColor

public void setLEDColor(int index,
                        double r,
                        double g,
                        double b)

sets a particular LED in the string to a certain color

Specified by:

setLEDColor in interface CasseroleLEDInterface

Parameters:

index - Index in the LED to set. 0 is the furthest from the roboRIO, N is the closest.

r - Red value for the color. Provide as a double in the range of 0 (off) to 1 (full on)

g - Green value for the color. Provide as a double in the range of 0 (off) to 1 (full on)

b - Blue value for the color. Provide as a double in the range of 0 (off) to 1 (full on)
