Colour Sensor (Grove 101020341) component

Based on the color sensor TCS34725FN with digital output I2C. Based on the 8*2 array of filtered photodiodes and 16-bits analog-to-digital converters, you can gain the color chromaticity of ambient light or the color of objects. Of the 16 photodiodes, 4 have red filters, 4 have green filters, 4 have blue filters and 4 have no filter(clear). With the synchronization input pin, external pulsed light source can provides precise synchronous conversion control.

Macro reference

CalculateLux

	CalculateLux
Uses the RGB values stored in RAM from the last Sample to calculate the luminance in lux.
- UINT	Return

CalculateTemp

	CalculateTemp
Uses the RGB values stored in RAM from the last Sample to calculate the colour temperature in degrees Kelvin.
- UINT	Return

ClearInterrupt

	ClearInterrupt
Clears the interrupt flag allowing the device to interrupt again.
- VOID	Return

ControlInterrupt

	ControlInterrupt
Enables or Disables the Interrupt pin to fire when the light levels are inside the interrupt limits.
- BYTE	Enable
Range: 0 to 1 - 0=Interrupt Off / 1=Interrupt On
- UINT	LowLevel
- UINT	HighLevel
- VOID	Return

DisableSensor

	DisableSensor
Powers down the device to save power.
- VOID	Return

EnableSensor

	EnableSensor
Powers up the device ready for taking colour readings.
- VOID	Return

Initialise

	Initialise
Initialise the sensor configuration as set by the component properties. Sets the default intigration time and gain as well as enable the sensor.
- VOID	Return

ReadDataChannel

	ReadDataChannel
Returns the value of the selected colour channel from the last sample. The Red, Green and Blue channels have a colour filter to remove light of other colours. The Clear channel has no filter allowing the ambient light level to be easily collected.
- BYTE	ColourChannel
Range: 0 to 3 - 0=Red, 1=Green, 2=Blue, 3=Clear
- UINT	Return

SampleSensor

	SampleSensor
Reads the raw colour channels from the sensor and stores the readings into RAM to be collected by the ReadDataChannel macro.
- VOID	Return

SetGain

	SetGain
Controls the gain. 0x00 = 1X 0x01 = 4X 0x02 = 16X 0x03 = 60X
- BYTE	Setting
Range: 0 to 3
- VOID	Return

SetIntegrationTime

	SetIntegrationTime
Controls the integration time. 0 = 700mS / 1 = 154mS / 2 = 101mS / 3 = 50mS / 4 = 24mS / 5 = 2.4mS
- BYTE	Setting
Range: 0 to 5
- VOID	Return

Property reference

	Properties
	Sensor Settings
	Integration Time
Length of time period used to sample the sensor frequency (longer is more accurate)
	Gain
Length of time period used to sample the sensor frequency (longer is more accurate)
	Connections
	Channel
Channel selection
	Mode
Defines if the component will be used for Master or Slave communications. Master mode supports a software bitbanged I2C channel. Slave mode requires a hardware I2C peripheral to catch the communications from the Master.
	SDA
Pin used for SDA (data signal)
	SDA Remap Pin
	SCL
Pin used for SCL (clock signal)
	SCL Remap Pin
	Simulation
	Simulation Type
Selects the simulation type for the component. Component GUI - Interacts with the panel to sense the colour of a object in close proximity to the sensor. I2C Injector - Performs the I2C commands allowing you to connect an injector component or view and debug the I2C communications.
