Functional description

2.4

Ranging operating modes

There are 3 ranging modes available in the API:

Single ranging

Ranging is performed only once after the API function is called.

System returns to SW standby automatically.

Continuous ranging

Ranging is performed in a continuous way after the API function is called. As soon as

the measurement is finished, another one is started without delay.

User has to stop the ranging to return to SW standby. The last measurement is

completed before stopping.

Timed ranging

Ranging is performed in a continuous way after the API function is called. When a

measurement is finished, another one is started after a user defined delay.

This delay (inter-measurement period) can be defined through the API.

User has to stop the ranging to return to SW standby.

If the stop request comes during a range measurement, the measurement is completed

before stopping. If it happens during an inter-measurement period, the range measurement

stops immediately.

2.5

Ranging profiles

There are 4 different ranging profiles available via API example code. Customers can create

their own ranging profile dependent on their use case performance requirements.

For more details please refer to the VL53L0X API User Manual.
