Function Documentation

artnetSetChans()

void artnetSetChans	(	uint8_t	minCh,
		uint8_t	maxCh )

Restricts the Art-Net channel range that is forwarded.

Parameters

minCh	First channel (1-based) to accept.
maxCh	Last channel (1-based) to accept.

artnetSetup()

void artnetSetup

(

)

Initializes the Art-Net receiver and wires its frame callback.

DMXCheck()

void DMXCheck

(

void

)

DMX housekeeping called from the main loop: propagates changes and services pending DMX-in updates.

DMXImmediateUpdate()

void DMXImmediateUpdate	(	short	tch,
		short	r,
		short	g,
		short	b,
		short	w )

DMXinSetup()

void DMXinSetup

(

int

channels

)

Sets up the DMX input for the given number of channels.

Parameters

channels

Number of DMX input channels.

ToDo: re-init

DMXOUT_propagate()

void DMXOUT_propagate

(

)

Smoothly ramps the actual DMX output toward the buffered target.

DMXoutSetup()

void DMXoutSetup

(

int

channels

)

Sets up the DMX output for the given number of channels.

Parameters

channels

Number of DMX output channels.

DMXput()

void DMXput

(

void

)

Propagates received DMX input frames to the mapped items.

DMX in/out is handled per platform: on the SAM3X8E (Due) a hardware USART (DmxDue) is used for both input and output; on AVR a software bit-banged driver (DmxSimple for output on pin 3/18, DMXSerial for input). ESP8266/ESP32 use ESPDMX.

DMXSemiImmediateUpdate()

void DMXSemiImmediateUpdate	(	short	tch,
		short	r,
		short	g,
		short	b,
		short	w )

DMXUpdate()

void DMXUpdate

(

void

)

DmxWriteBuf()

void DmxWriteBuf	(	uint16_t	chan,
		uint8_t	val )

Writes a value into the intermediate (smoothing) DMX output buffer.

Parameters

chan	1-based DMX channel.
val	Channel value 0..255.

itemCtrl2()

int itemCtrl2	(	char *	name,
		int	r,
		int	g,
		int	b,
		int	w )

Drives a named DMX/LED item with an RGB(W) value.

Parameters

name	Name of the target item.
r	Red component.
g	Green component.
b	Blue component.
w	White component.

Returns

1 on success, 0 if the item was not found.

onDmxFrame()

void onDmxFrame	(	uint16_t	universe,
		uint16_t	length,
		uint8_t	sequence,
		uint8_t *	data,
		IPAddress	remoteIP )

rgb2hsv()

itemCmd rgb2hsv

(

itemCmd

in

)
