Detailed Description

Class that stores state and functions for interacting with LPD6803 RGB Pixels.

Constructor & Destructor Documentation

LPD6803()

LPD6803::LPD6803	(	uint16_t	n,
		uint8_t	dpin,
		uint8_t	cpin
	)

LPD6803 constructor.

Parameters

n	Number of pixels
dpin	Data pin
cpin	Clock pin

Member Function Documentation

doSwapBuffersAsap()

void LPD6803::doSwapBuffersAsap

(

uint16_t

idx

)

Update the pixels when next possible.

Parameters

idx	Which LED we are updating

setPixelColor() [1/2]

void LPD6803::setPixelColor	(	uint16_t	n,
		uint8_t	r,
		uint8_t	g,
		uint8_t	b
	)

Set a pixel's color using separate red, green and blue components.

Parameters

n	Pixel index, starting from 0
r	Red brightness, 0 = minimum (off), 255 = maximum
g	Green brightness, 0 = minimum (off), 255 = maximum
b	Blue brightness, 0 = minimum (off), 255 = maximum

setPixelColor() [2/2]

void LPD6803::setPixelColor	(	uint16_t	n,
		uint16_t	c
	)

Set a pixel's color using a 32-bit 'packed' RGB or RGBW value.

Parameters

n	Pixel index, starting from 0.
c	32-bit color value. Most significant byte is white (for RGBW pixels) or ignored (for RGB pixels), next is red, then green, and least significant byte is blue

setCPUmax()

void LPD6803::setCPUmax

(

uint8_t

m

)

Sets max cpu speed.

Parameters

m	max CPU clock speed, in MHz

numPixels()

uint16_t LPD6803::numPixels

(

void

)

Number of pixels connected.

Returns

Returns a 16-bit signed int equal to how many pixels are connected
