setProximityHz()

SetProximityHz([Hertz])

Proximity is measured with an IR transmitter and receiver on the VCNL4010. This function accepts an unsigned integer number representing the Hertz rate used to scan. The number entered is set to the closest actual internal setting which ranges from the default 1.95 measurements per second up to 250 measurements per second. The following table lists the discrete values used by the VCNL4010:

Binary Value	Measurement frequency
000	1.95 measurements/s
001	3.90625 measurements/s
010	7.8125 measurements/s
011	16.625 measurements/s
100	31.25 measurements/s
101	62.5 measurements/s
110	125 measurements/s
111	250 measurements/s

Example:

VCNL4010 Sensor();          // Instantiate class    
...    
while(!Sensor.begin());     // loop until initialized
Sensor.setProximityHz(230); // gets rounded down to 125Hz
