setInterrupt()

setInterrupt([Count][,ProximityReady][,ALSReady][,ProxThreshold][,ALSThreshold][,lowValue][,highValue])

This function allows the use of the interrupt output of the VCNL4010. By default this pin is pulled high but when an interrupt is triggered by the events set by this call the pin is pulled low and this can be used on the Arduino to set a pin change interrupt which can be very useful. One example is to set an interrupt when the proximity sensor detects movement and keep the processor into energy-saving state.

The parameters are as follow:

Name	Type	Default	Description
Count	uint8	1	The number of events needed to trigger an interrupt
Proximity Ready	boolean	false	Whether or not to trigger an interrupt when a proximity reading is ready
ALS Ready	boolean	false	Whether or not to trigger an interrupt when an ambient light sensor reading is ready
Proximity Threshold	boolean	false	When true, use the low and high threshold numbers for proximity readings and trigger an interrupt when either threshold has been exceeded
ALS Threshold	boolean	false	When true, use the low and high threshold numbers for ambient light sensor readings and trigger an interrupt when either threshold has been exceeded
Low Threshold value	uint16	0	The low threshold value, when a reading is lower than this value an interrupt is set
High Threshold value	uint16	65536	The high threshold value, when a reading is higher than this value an interrupt is set

Once an interrupt has been raised and the pin pulled down, the condition remains until explicitly cleared by the user using the clearInterrupt() function.

Example:

VCNL4010 Sensor();      // Instantiate class    
... 
while(!Sensor.begin()); // loop until initialized   
Sensor.setInterrupt(1,false,false,false,true,500,32000); 
// Trigger an interrupt when the proximity reads below 500 or over 32000 //
