System functional description

Figure 4 shows the system level functional description. The host customer application

controls the VL53L1 device using an API (application programming interface). The API

implementation is delivered to the customer as a driver (Bare C code, or Linux/Android

driver).

The driver shares with the customer application a set of high level functions that allow

control of the VL53L1 firmware like initialization, ranging start/stop, setting the system

accuracy, and choice of ranging mode.

The driver is a turnkey solution consisting of a set of “C” functions that enables fast

development of end user applications without the complication of direct multiple register

access. The driver is structured in a way that it can be compiled on any kind of platform

through a well abstracted platform layer. The driver package allows the user to take full

advantage of VL53L1 capabilities.

A detailed description of the driver is available in the VL53L1 driver user manual

(UM2133).

The VL53L1 firmware fully manages the hardware register accesses.

Section 2.2: Firmware state machine description details the firmware state machine.
