Constructor & Destructor Documentation

Adafruit_TLC5947()

Adafruit_TLC5947::Adafruit_TLC5947	(	uint16_t	n,
		uint8_t	c,
		uint8_t	d,
		uint8_t	l
	)

Instantiates a new TLC5947 class.

n	num of drivers (boards)
c	Arduino pin connected to TLC5947 clock pin
d	Arduino pin connected to TLC5947 data pin
l	Arduino pin connected to TLC5947 latch pin

Member Function Documentation

begin()

boolean Adafruit_TLC5947::begin

(

void

)

Setups the HW.

Returns

True if initialization was successful, otherwise false.

setPWM()

void Adafruit_TLC5947::setPWM	(	uint16_t	chan,
		uint16_t	pwm
	)

Set the PWM channel / value.

Parameters

chan	channel number ([0 - 23] on each board, so channel 2 for second board will be 25)
pwm	pwm value [0-4095]

getPWM()

uint16_t Adafruit_TLC5947::getPWM

(

uint16_t

chan

)

Get the PWM value for channel.

Parameters

chan	channel number ([0 - 23] on each board, so channel 2 for second board will be 25)

Returns

PWM value ([0 - 4095]) for valid channels, 0 for non-existing channels.

setLED()

void Adafruit_TLC5947::setLED	(	uint16_t	lednum,
		uint16_t	r,
		uint16_t	g,
		uint16_t	b
	)

Set LED.

Parameters

lednum	led number
r	red value [0-255]
g	green value [0-255]
b	blue value [0-255]
