start

start

initiates a single Measurement.
If you come from other libraries, here you will not find a continuous measurement mode!
In this mode, you are not able to control the sensor in the way this library does.

 bool start();
 bool start(BH1750Quality quality, byte mtreg);

---

result Boolean

true, on successful communication.
This command is send physically to the sensor.
Internally, the Quality is always sent.

---

Parameter BH1750Quality quality

If leave empty, the last or default Quality is used.
See also setQuality().

---

Parameter byte mtreg

If left empty, the last or default MTreg is used.
See also setMtreg().

Hints:

You can only use all two parameters, or none Parameters!

When used in conjunction with adjustSettings(), the brackets must be empty!
Otherwise you would overwrite the internal adjusted settings.

If a measurement is already running, it is aborted and a new measurement is started.
