Proximity 19 Click is a compact add-on board designed for precise proximity sensing in various applications. This board features the RPR-0720, a digital optical proximity sensor from ROHM Semiconductor. The RPR-0720 integrates an infrared VCSEL (IrVCSEL) and an IC with an I2C interface, featuring a detection range adjustable from 1 to 15mm and an ambient light canceling function. The board uses a 2-wire I2C interface for communication, supporting up to 400kHz frequency clock, allowing control over sensor functions such as operating mode, interrupt system, and offset/threshold adjustments.

Click library

  • Author : Nenad Filipovic
  • Date : Jan 2024.
  • Type : I2C type

Software Support

We provide a library for the Proximity 19 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Proximity 19 Click driver.

Standard key functions :

  • proximity19_cfg_setup Config Object Initialization function.

    void proximity19_cfg_setup ( proximity19_cfg_t *cfg );
  • proximity19_init Initialization function.

    err_t proximity19_init ( proximity19_t *ctx, proximity19_cfg_t *cfg );
  • proximity19_default_cfg Click Default Configuration function.

    err_t proximity19_default_cfg ( proximity19_t *ctx );

Example key functions :

  • proximity19_get_distance This function reads the distance measured by the sensor in millimeters by using the I2C serial interface.

    err_t proximity19_get_distance ( proximity19_t *ctx, float *distance );
  • proximity19_set_ps_gain This function adjusts the gain of the sensor's sensitivity to light reception.

    err_t proximity19_set_ps_gain ( proximity19_t *ctx, uint8_t ps_gain );
  • proximity19_set_period This function sets the desired data measurement period value.

    err_t proximity19_set_period ( proximity19_t *ctx, uint8_t period );

Example Description

This example demonstrates the use of the Proximity 19 Click board by measuring and displaying the distance data.

The demo application is composed of two sections :

Application Init

Initialization of I2C module and log UART. After the driver init, the app executes a default configuration.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    proximity19_cfg_t proximity19_cfg;  /**< Click config object. */

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );

    // Click initialization.
    proximity19_cfg_setup( &proximity19_cfg );
    PROXIMITY19_MAP_MIKROBUS( proximity19_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == proximity19_init( &proximity19, &proximity19_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( PROXIMITY19_ERROR == proximity19_default_cfg ( &proximity19 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
}

Application Task

The demo app measures the distance between the sensor and the object in millimeters and displays the result approximately every 100 milliseconds. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void ) 
{
    float distance = 0;
    if ( PROXIMITY19_OK == proximity19_get_distance( &proximity19, &distance ) )
    {
        log_printf( &logger, " Distance: %.2f [mm] \r\n\n", distance );
    }
    Delay_ms ( 100 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Proximity19

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. UART terminal is available in all MikroElektronika compilers.

Magneto 12 Click is a compact add-on board that contains an accurate and reliable magnetic sensing device. This board features the A31315, a magnetic position sensor designed for on- and off-axis rotary and linear stroke position measurement from Allegro Microsystems. This sensor integrates vertical and planar Hall-effect elements with precision temperature-compensating circuitry to detect two out of three magnetic field components (X and Y). Using configurable signal processing (the user is allowed to process the output signal in analog or digital form), linearization and angle calculation allows the A31315 to accurately resolve the absolute rotary (full 360° and short-stroke <360°) or linear position of a moving magnetic target.
