Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : I2C type

Software Support

We provide a library for the ProxFusion2 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 ProxFusion2 Click driver.

Standard key functions :

  • proxfusion2_cfg_setup Config Object Initialization function.

    void proxfusion2_cfg_setup ( proxfusion2_cfg_t *cfg ); 
  • proxfusion2_init Initialization function.

    err_t proxfusion2_init ( proxfusion2_t *ctx, proxfusion2_cfg_t *cfg );
  • proxfusion2_default_cfg Click Default Configuration function.

    err_t proxfusion2_default_cfg ( proxfusion2_t *ctx );

Example key functions :

  • proxfusion2_detect_touch Function for detect Touch

    uint8_t proxfusion2_detect_touch ( proxfusion2_t *ctx );
  • proxfusion2_detect_dark_light Function for read ambient light

    uint8_t proxfusion2_detect_dark_light ( proxfusion2_t *ctx, uint8_t *als_range );
  • proxfusion2_detect_hall Function for read Hall-effect

    uint8_t proxfusion2_detect_hall ( proxfusion2_t *ctx );

Examples Description

This example demontrates the use of ProxFusion 2 Click board.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the Click default configuration.


void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    proxfusion2_cfg_t proxfusion2_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.
    proxfusion2_cfg_setup( &proxfusion2_cfg );
    PROXFUSION2_MAP_MIKROBUS( proxfusion2_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == proxfusion2_init( &proxfusion2, &proxfusion2_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( PROXFUSION2_ERROR == proxfusion2_default_cfg ( &proxfusion2 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

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

Application Task

  • Checks whether Touch is detected and measures the output detection.
  • Measures Ambient lighting - whether it's Light or Dark, ALS range and ALS output.
  • Checks the orientation of the magnet and measures the HALL output.

void application_task ( void )
{
    uint8_t als_range = 0;
    uint8_t hall_detect = 0;
    uint16_t read_data = 0;
    if ( PROXFUSION2_TOUCH_DETECTED == proxfusion2_detect_touch( &proxfusion2 ) )
    {
        log_printf( &logger, " TOUCH: YES\r\n" );
    }
    else
    {
        log_printf( &logger, " TOUCH: NO\r\n" );
    }
    read_data = proxfusion2_read_data( &proxfusion2 , PROXFUSION2_HYSTERESIS_UI_OUTPUT );
    log_printf( &logger, " LEVEL: %u\r\n\n", read_data );

    if ( PROXFUSION2_AMBIENT_DARK == proxfusion2_detect_dark_light( &proxfusion2, &als_range ) )
    {
        log_printf( &logger, " AMBIENT: DARK\r\n" );
    }
    else
    {
        log_printf( &logger, " AMBIENT: LIGHT\r\n" );
    }
    log_printf( &logger, " RANGE: %u\r\n", ( uint16_t ) als_range );

    read_data = proxfusion2_read_data( &proxfusion2, PROXFUSION2_ALS_UI_OUTPUT );

    log_printf( &logger, " LEVEL: %u\r\n\n", read_data );

    hall_detect = proxfusion2_detect_hall( &proxfusion2 );
    if ( PROXFUSION2_HALL_NORTH == hall_detect )
    {
        log_printf( &logger, " HALL: NORTH\r\n" );
    }
    else if ( PROXFUSION2_HALL_SOUTH == hall_detect )
    {
        log_printf( &logger, " HALL: SOUTH\r\n" );
    }
    else
    {
        log_printf( &logger, " HALL: UNKNOWN\r\n" );
    }
    read_data = proxfusion2_read_data( &proxfusion2, PROXFUSION2_HALL_EFFECT_UI_OUTPUT );
    log_printf( &logger, " LEVEL: %u\r\n", read_data );

    log_printf( &logger, " --------------\r\n" );
    Delay_ms ( 1000 );
}

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.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.ProxFusion2

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.
