HOW DOES IT WORK?
LightRanger11 Click is based on the VL53L7CX, a time-of-flight 8x8 multizone ranging sensor from STMicroelectronics. This ToF sensor integrates a VCSEL (vertical-cavity surface-emitting laser), which emits an entirely invisible 940nm IR light, totally safe for eyes (Class 1 certification), and a SPAD (single-photon avalanche diode) array which helps the VL53L7CX to achieve the best-ranging performance even when a Click board™ is hidden behind a wide range of cover glass materials. In addition, the sensor is equipped with diffractive optical elements (DOE) on both the transmitter and the receiver, enabling square FoV.
Designed explicitly for small-range and multi-target measurements, the VL53L7CX provides very accurate distance measurements up to 350cm with excellent results over short distances and 60° x 60° square field of view (FoV) (90° diagonal), which improves performances under ambient light. Thanks to ST's patented algorithms, the VL53L7CX can detect multiple objects within the FoV with depth understanding. ST histogram algorithms ensure cover glass crosstalk immunity beyond 60cm. Like all Time-of-Flight sensors based on ST's FlightSense technology, the VL53L7CX records an absolute distance measurement regardless of the target color and reflectance.
LightRanger 11 Click uses a standard 2-Wire I2C interface to communicate with the host MCU, read data, and configure settings with a maximum clock frequency of up to 1MHz. The I2C interface on Click board™ can be reset through the RSC pin of the mikroBUS™ socket, hence offering a switch operation to turn ON the initial I2C starting sequence of the VL53L7CX. It also possesses an additional interrupt pin, routed to the INT pin on the mikroBUS™ socket, indicating when a ranging measurement is available. An LP pin lets you turn the I2C communication on or off when in low power mode, which is used when it is required to change the I2C address in multi-device systems.
This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. Also, this Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used as a reference for further development.
