概要

The VL53L7CX_ULD API is a set of C functions controlling the VL53L7CX device (for example, init and ranging) to enable the development of end-user applications. The VL53L7CX ULD is an optimized driver with only three files required for basic ranging. More features can be added with plug-in systems. The API can be compiled on any type of platform through a well isolated platform layer (mainly for low-level I²C access). One example code is provided to show how to use the API and to perform ranging measurements.

Specially designed for applications requiring an ultrawide field of view (FoV), the VL53L7CX Time-of-Flight sensor offers a 90° diagonal FoV. Based on ST's FlightSense technology, the VL53L7CX incorporates an efficient metasurface lens (DOE) placed on the laser emitter. This enables the projection of a 60° x 60° square FoV onto the scene.

Its multizone capability provides a matrix of 8x8 zones (64 zones) and can work at fast speeds (60 Hz) up to 350 cm.

Thanks to the autonomous mode with programmable distance threshold, combined to the ultrawide FoV, the VL53L7CX is perfect for any application requiring low-power user detection. ST's patented algorithms and innovative module construction allow the VL53L7CX to detect, in each zone, multiple objects within the FoV with depth understanding. ST histogram algorithms ensure cover glass crosstalk immunity beyond 60 cm.

The VL53L7CX is the perfect sensor for any application requiring ultrawide FoV like robotics, smart speakers, video projectors, and content management. The combination of the multizone capability and the 90° FoV can enhance new use-cases like gesture recognition, SLAM for robotics, and low power system activation for smart building.
