La carte Click Board™ Proximity 16 est une carte complémentaire compacte qui contient une solution de détection de proximité à courte portée. Cette carte comprend le VL53L5CX, un capteur de télémétrie multizone à temps de vol (ToF) de STMicroelectronics. Le VL53L5CX intègre un réseau SPAD, des filtres infrarouges physiques et des éléments optiques diffractifs (DOE) pour obtenir les meilleures performances de télémétrie dans diverses conditions d'éclairage ambiant avec différents matériaux de verre de protection. Il permet une mesure de distance absolue, quelle que soit la couleur et la réflectivité de la cible, fournit une télémétrie précise jusqu'à 400 cm et peut fonctionner à des vitesses rapides (60 Hz). De plus, des mesures de distance multizones sont possibles avec des zones séparées 4x4 ou 8x8 avec un large champ de vision (FoV) configurable par logiciel en diagonale de 63°. Cette carte Click™ convient à la détection de distance multizone et multi-objet, à la gestion de contenu, à la reconnaissance de gestes et à diverses applications grand public et industrielles.
La carte Click Board™ Proximity 16 est supportée par une bibliothèque compatible mikroSDK, qui comprend des fonctions qui simplifient le développement logiciel. Cette carte Click Board™ est un produit entièrement testé, prêt à être utilisé sur un système équipé du socket mikroBUS™.
How Does The Proximity 16 Click Board™ Work?
The Proximity 16 Click Board™ as its foundation uses the VL53L5CX, an 8x8 multi-zone Time-of-Flight sensor with wide FoV for each zone from STMicroelectronics. The VL53L5CX offers multi-target detection and distance measurement in each zone up to 4 meters. It integrates a SPAD array, physical infrared filters, and diffractive optical elements to achieve the best-ranging performance in various ambient lighting conditions. Also, with ST's patented histogram algorithms, the VL53L5CX detects multiple objects within the FoV and ensures immunity to cover glass crosstalk beyond 60cm.
Using diffractive optical elements above the vertical cavity surface emitting laser (VCSEL) allows a square field-of-view of 45°x45° (63° diagonal) to be projected onto the scene, where the receiver lens focuses the light reflection onto a SPAD array. The VL53L5CX can range up to 8x8 zones at 15Hz for higher resolution or 4x4 zones at 60Hz for faster-ranging measurements.
The Proximity 16 Click Board™ communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings, supporting Fast Mode Plus Mode up to 1MHz. Also, this Click board™ provides the ability to use I2C communication in Low-Power mode, which activates via the setting of the LP pin routed to the PWM pin on the mikroBUS™ socket. Besides, it provides an intelligent interrupt function that generates every time a ranging measurement is available, alongside an I2C Reset feature routed to the RST pin on the mikroBUS™ socket, which resets the sensor I2C communication only. Once the host reads the result, the interrupt is cleared, and the ranging sequence can repeat.
The Proximity 16 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. However, the Click board™ comes equipped with a library containing functions and an example code that can be used, as a reference, for further development.

Software Support
We provide a library for the Proximity 16 Click Board™ as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
The package can be downloaded/installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on MikroE Github account.
Library Description
This library contains API for the Proximity 16 Click Board™ driver.
Key functions
-
proximity16_get_int_pinThis function returns the INT pin logic state. -
proximity16_get_resolutionThis function gets the current resolution (4x4 or 8x8). -
proximity16_get_ranging_dataThis function gets the ranging data, using the selected output and the resolution.
Example Description
This example demonstrates the use of the Proximity 16 Click Board™ by reading and displaying 8x8 zone measurements on the USB UART.

Additional Notes and Information
Depending on the development board you are using, you may need USB UART Click Board™, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
MIKROSDK
The Proximity 16 Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
