SR03 settings

Below are the recommended settings required to be loaded onto the VL6180X during the

initialisation of the device (see Section 1.3).

// Mandatory : private registers

WriteByte(0x0030, 0x00);

// Recommended : Public registers - See data sheet for more detail

WriteByte(0x0011, 0x10); // Enables polling for ‘New Sample ready’

// when measurement completes

WriteByte(0x010a, 0x30); // Set the averaging sample period

// (compromise between lower noise and

// increased execution time)

WriteByte(0x003f, 0x46); // Sets the light and dark gain (upper

// nibble). Dark gain should not be

// changed.

WriteByte(0x0031, 0xFF); // sets the # of range measurements after

// which auto calibration of system is

// performed

WriteByte(0x0040, 0x63); // Set ALS integration time to 100ms
