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 |
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. Returns 1 if the sensor is detected and responding to commands. | |
 - BOOL
|
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 |
SetIntegrationTime
|
|
SetIntegrationTime |
| Controls the integration time. 0 = 40mS / 1 = 80mS / 2 = 160mS / 3 = 320mS / 4 = 640mS / 5 = 1280mS | |
| - BYTE
|
Setting |
| Range: 0 to 5 | |
| - VOID
|
Return |

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 |
|
|
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. | |
