Proximity 3 click

Proximity 3 click is an intelligent proximity and light sensing device, which features the VCNL4200 sensor from Vishay - high sensitivity long distance proximity sensor (PS), ambient light sensor (ALS) and 940 nm IRED, all in one small package.

Click library

Software Support

We provide a library for the Proximity3 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Proximity3 Click driver.

Standard key functions :

Example key functions :

Examples Description

This example reads the data from the ambient light sensor and converts the data into digital form using calculations.

The demo application is composed of two sections :

Application Init

Initialization driver enables - I2C, initializes VCNL4100, write configuration register and starts to write log to Usart Terminal.

void application_init ( void )
{
log_cfg_t log_cfg;
// Logger initialization.
log_cfg.level = LOG_LEVEL_DEBUG;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
PROXIMITY3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
proximity3_init( &proximity3, &cfg );
// Default startup options for Ambient Light Sensor
Delay_ms( 10 );
// Default startup options for Proximity
Delay_ms( 10 );
Delay_ms( 10 );
// Set the proximity interrupt levels
Delay_10ms();
Delay_10ms();
// Check device ID
{
log_printf( &logger, " ERROR");
}
else
{
log_printf( &logger, " Initialization" );
log_printf( &logger, "--------------------------" );
}
Delay_100ms();
}

Application Task

This is a example which demonstrates the use of Proximity 3 Click board. Measured distance ( proximity ) and illuminance ( abmient light ) from sensor, results are being sent to the Usart Terminal where you can track their changes. All data logs on usb uart for aproximetly every 3 sec.

void application_task ( void )
{
Delay_ms( 10 );
log_printf( &logger, " Proximity: %d cm", result_proximity );
log_printf( &logger, " Ambient Light: %d lux", result_ambient_light );
log_printf( &logger, "-----------------------------------------" );
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, 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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
