Macro reference

GetBrightness

	GetBrightness
Gets the brightness of a single LED.
- BYTE	Address
Range: 0-11
- BYTE	RGB
Byte array containing at least 3 bytes to store Red, Green and Blue
- BYTE	Return

GetDiscreteRGB

	GetDiscreteRGB
Gets the RGB format colour of a single LED.
- BYTE	Address
Range: 0-11
- BYTE	ColourIndex

- BYTE	Return

GetRGB

	GetRGB
Gets the RGB colour of a single LED. Array variables only. For individual variables, use GetDiscreteRGB
- BYTE	Address
Range: 0-11
- BYTE	RGB
Byte array containing at least 3 bytes to store Red, Green and Blue
- VOID	Return

Initialise

	Initialise
Starts up the I2C comms ready for communicating with the LP503x module. Must be called before any of the other component macros are called.
- VOID	Return

ReadReg

	ReadReg
Reads the data from one or more sequential registers
- BYTE	Address

- BYTE	Data

- BYTE	Count

- VOID	Return

SetBrightness

	SetBrightness
Allows the brightness of a single LED to be specified as a byte from 0 to 255. Default on reset is 255.
- BYTE	Address
Range: 0-11
- BYTE	Brightness
Brightness value: Range 0-255
- VOID	Return

SetDiscreteRGB

	SetDiscreteRGB
Allows the colour of a single LED to be specified in RGB format
- BYTE	Address
Range: 0-11
- BYTE	Red

- BYTE	Green

- BYTE	Blue

- VOID	Return

SetRGB

	SetRGB
Allows the colour of a single LED to be specified in RGB. Array variables only. For individual variables and literal values, use SetDiscreteRGB
- BYTE	Address
Range: 0-11
- BYTE	RGB
Byte array containing at least 3 bytes to set Red, Green and Blue
- VOID	Return

SetUnitAddress

	SetUnitAddress
Allows the component to taklk to more then one IC or broadcast to all connected ICs.
- BYTE	Address
Range: 0-3 = Individual / 4 = Broadcast
- VOID	Return

WriteReg

	WriteReg
Writes data to one or more sequential registers
- BYTE	Address

- BYTE	Data

- BYTE	Count

- VOID	Return

Property reference

	Properties
	Driver
	Driver IC

	Address Pins

	Connections
	Channel
Channel selection
	Baud Select
Baud rate option selector
	Baud Rate
Baud rate to be used
	SDA
Pin used for SDA (data signal)
	SDA Remap Pin

	SCL
Pin used for SCL (clock signal)
	SCL Remap Pin

	Stop Delay
On older microcontroller devices there is a potential for the I2C hardware channel to lock up if there is not a 10ms delay between an I2C stop event and the next I2C start event. Most modern microcontrollers will not have a problem so this property can be disabled to speed up the I2C communications.
	Simulation
	Simulate Comms
