Member Function Documentation

dDefine()

void Channels::dDefine	(	uint16_t	x0,
		uint16_t	y0,
		uint16_t	dx,
		uint16_t	dy,
		int32_t	valueMin,
		int32_t	valueMax,
		int32_t	unit = 1,
		uint8_t	channels = 4,
		uint8_t	sectionsY = 4,
		uint16_t	valueColour = myColours.black )

Define the graphic, vector coordinates.

Parameters

x0	point coordinate, x-axis
y0	point coordinate, y-axis
dx	length, x-axis
dy	height, y-axis
valueMin	minimum value for measures, already multiplied by unit
valueMax	maximum value for measures, already multiplied by unit
unit	multiplier for all values, default = 1, 10 or 100
channels	number of channels, default = 4
sectionsY	number of sections on the y axis, default = 4, 0 = no grid
valueColour	16-bit colour for measures, default = black, optional

More: Coordinates, Colours, Value

define()

void Channels::define	(	uint16_t	x1,
		uint16_t	y1,
		uint16_t	x2,
		uint16_t	y2,
		int32_t	valueMin,
		int32_t	valueMax,
		int32_t	unit = 1,
		uint8_t	channels = 4,
		uint8_t	sectionsY = 4,
		uint16_t	valueColour = myColours.black )

Define the graphic, rectangle coordinates.

Parameters

x1	top left coordinate, x-axis
y1	top left coordinate, y-axis
x2	bottom right coordinate, x-axis
y2	bottom right coordinate, y-axis
valueMin	minimum value for measures, already multiplied by unit
valueMax	maximum value for measures, already multiplied by unit
unit	multiplier for all values, default = 1, 10 or 100
channels	number of channels, default = 4
sectionsY	number of sections on the y axis, default = 4, 0 = no grid
valueColour	16-bit colour for measures, default = black, optional

More: Coordinates, Colours, Value

draw()

void Channels::draw	(	uint8_t	channel,
		int32_t	value )

Update the graphic.

Parameters

channel	channel to update, 0..channels - 1
value	new measure, already multiplied by unit

Note

If value = 1234 with unit = 100, actual value is 1234/100 = 12.34

More: Value
