Matrix is an interface that represent any RGB matrix, very useful for testing

func BuildMatrix 

func BuildMatrix(config *MatrixConfig) (Matrix, error)

func NewEmulator 

func NewEmulator(config *MatrixConfig) (Matrix, error)

func NewRGBLedMatrix 

func NewRGBLedMatrix(config *MatrixConfig) (c Matrix, err error)

NewRGBLedMatrix returns a new matrix using the given size and config

func NewRpcClient 

func NewRpcClient(config *MatrixConfig) (Matrix, error)

type MatrixConfig 

type MatrixConfig struct {
	// Rows the number of rows supported by the display, so 32 or 16.
	Rows int
	// Cols the number of columns supported by the display, so 32 or 64 .
	Cols int
	// ChainLength is the number of displays daisy-chained together
	// (output of one connected to input of next).
	ChainLength int
	// Parallel is the number of parallel chains connected to the Pi; in old Pis
	// with 26 GPIO pins, that is 1, in newer Pis with 40 interfaces pins, that
	// can also be 2 or 3. The effective number of pixels in vertical direction is
	// then thus rows * parallel.
	Parallel int
	// Set PWM bits used for output. Default is 11, but if you only deal with
	// limited comic-colors, 1 might be sufficient. Lower require less CPU and
	// increases refresh-rate.
	PWMBits int
	// Change the base time-unit for the on-time in the lowest significant bit in
	// nanoseconds.  Higher numbers provide better quality (more accurate color,
	// less ghosting), but have a negative impact on the frame rate.
	PWMLSBNanoseconds int // the DMA channel to use
	// Brightness is the initial brightness of the panel in percent. Valid range
	// is 1..100
	Brightness int
	// ScanMode progressive or interlaced
	ScanMode ScanMode // strip color layout
	// Disable the PWM hardware subsystem to create pulses. Typically, you don't
	// want to disable hardware pulsing, this is mostly for debugging and figuring
	// out if there is interference with the sound system.
	// This won't do anything if output enable is not connected to GPIO 18 in
	// non-standard wirings.
	DisableHardwarePulsing bool

	ShowRefreshRate bool
	InverseColors   bool

	// Name of GPIO mapping used
	HardwareMapping string
	// Semicolon-separated list of pixel-mappers to arrange pixels.
	LedPixelMapper string
	// Using OpenGL emulator instead of driving hardware matrix
	Emulator bool
	// Driving remote matrix using GoRPC
	Client bool
	// Serving hardware matrix using GoRPC
	Server bool
	// Remote server address
	IpAddress string
