VL53L3CX Functional description 2 Functional description 2.1 System functional description
The figure below shows the system level functional description. The host customer application controls the device using an API (application programming interface). The API implementation is delivered to the customer as a driver (Bare C code, or Linux driver). The driver shares with the customer application a set of high level functions that allow control of the device Firmware (FW) like initialization, ranging start/stop, setting the system accuracy. The driver is a turnkey solution consisting of a set of “C” functions that enable 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 the device capabilities. A detailed description of the driver is available in the device driver user manual. The device FW fully manages the hardware (HW) register accesses. Section 2.2 State machine description details the Firmware state machine.
