ProxFusion 2 Click

ProxFusion 2 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Example 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 );

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 );

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 );

    if ( I2C_MASTER_ERROR == proxfusion2_init( &proxfusion2, &proxfusion2_cfg ) )
    {
        log_error( &logger, " Communication init." );
        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.

    uint8_t als_range = 0;
    uint8_t hall_detect = 0;
    uint16_t read_data = 0;

    }

}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
