Types

type Config

type Config struct {
	Width      int16
	Height     int16
	ColorDepth uint16
	RowPattern int16
	Brightness uint8
	FastUpdate bool
}

type Device

type Device struct {
	// contains filtered or unexported fields
}

func New

func New(b machine.SPI, latPin, oePin, aPin, bPin, cPin, dPin machine.Pin) Device

New returns a new HUB75 driver. Pass in a fully configured SPI bus.

func (*Device) ClearDisplay

func (d *Device) ClearDisplay()

ClearDisplay erases the internal buffer

func (*Device) Configure

func (d *Device) Configure(cfg Config)

Configure sets up the device.

func (*Device) Display

func (d *Device) Display() error

Display sends the buffer (if any) to the screen.

func (*Device) FlushDisplay

func (d *Device) FlushDisplay()

FlushDisplay flushes the display

func (*Device) SetBrightness

func (d *Device) SetBrightness(brightness uint8)

SetBrightness changes the brightness of the display

func (*Device) SetPixel

func (d *Device) SetPixel(x int16, y int16, c color.RGBA)

SetPixel modifies the internal buffer in a single pixel.

func (*Device) Size

func (d *Device) Size() (w, h int16)

Size returns the current size of the display.
