receivedStrandState

public void receivedStrandState(byte strandIndex,
                       NeoPixel.ColorOrdering order,
                       NeoPixel.StrandSpeed speed,
                       byte pin,
                       byte strandLength)

Called when the strand state has been read

Parameters:

strandIndex - Strand index read

order - Color ordering of the specific strand

speed - Interface speed of the strand

pin - GPIO pin on the MetaWear board the NeoPixel strand is connected to

strandLength - Number of pixels on the strand

receivedHoldState

public void receivedHoldState(byte strandIndex,
                     byte state)

Called when the strand's hold state has been read

Parameters:

strandIndex - Strand index read

state - 0 if disabled, 1 if enabled

receivedPixelColor

public void receivedPixelColor(byte strandIndex,
                      byte pixel,
                      byte red,
                      byte green,
                      byte blue)

Called when a pixel color has been read

Parameters:

strandIndex - Strand index the pixel resides on

pixel - Index of the pixel

red - Red color value

green - Green color value

blue - Blue color value

receivedRotatationState

public void receivedRotatationState(byte strandIndex,
                           NeoPixel.RotationDirection direction,
                           byte repetitions,
                           short period)

Called when the rotate state of a strand has been read

Parameters:

strandIndex - Strand index read

direction - Rotation direction i.e. away from or towards the board

repetitions - Number of times the rotation will occur, -1 if rotation is happening indefinitely

period - Delay between rotations in milliseconds
