ProxFusion 3 Click

ProxFusion 3 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.

Application Init

Initializes I2C driver, read and display version info value and start to write log.

void application_init ( void ) 
{
    log_cfg_t log_cfg;                  /**< Logger config object. */
    proxfusion3_cfg_t proxfusion3_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_printf( &logger, "\r\n---------------------------\r\n" );
    log_info( &logger, " Application Init " );

    // Click initialization.

    proxfusion3_cfg_setup( &proxfusion3_cfg );
    PROXFUSION3_MAP_MIKROBUS( proxfusion3_cfg, MIKROBUS_1 );
    err_t init_flag = proxfusion3_init( &proxfusion3, &proxfusion3_cfg );
    if ( init_flag == I2C_MASTER_ERROR ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    proxfusion3_default_cfg ( &proxfusion3 );
    log_info( &logger, " Application Task " );
    log_printf( &logger, "---------------------------\r\n" );
    Delay_ms ( 500 );
    
    proxfusion3_get_version_info( &proxfusion3, &product_number, &software_version );
    log_printf( &logger, "  Product Number   : 0x%.2X \r\n", ( uint16_t )product_number );
    log_printf( &logger, "  Software Version : 0x%.2X \r\n", ( uint16_t )software_version );
    log_printf( &logger, "---------------------------\r\n" );
    Delay_ms ( 1000 );
    log_printf( &logger, "      Touch Detection      \r\n" );
    log_printf( &logger, "---------------------------\r\n" );
}

Application Task

This is an example that demonstrates the use of the ProxFusion 3 Click board. In this example, we check the touch event and display the last detected touch. Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( void ) 
{
    if ( proxfusion3_check_touch_event( &proxfusion3 ) == PROXFUSION3_EVENT_TOUCH ) {        
        uint8_t touch_data = proxfusion3_get_touch( &proxfusion3 );
        Delay_ms ( 100 );
        
        switch ( touch_data ) {
            case PROXFUSION3_TOUCH_POS_8: {
                log_printf( &logger, "       >>>   8   <<<       \r\n" );
                break;
            }
            case PROXFUSION3_TOUCH_POS_7: {
                log_printf( &logger, "       >>>   7   <<<       \r\n" );
                break;
            }
            case PROXFUSION3_TOUCH_POS_6: {
                log_printf( &logger, "       >>>   6   <<<       \r\n" );
                break;
            }
            case PROXFUSION3_TOUCH_POS_5: {
                log_printf( &logger, "       >>>   5   <<<       \r\n" );
                break;
            }
            case PROXFUSION3_TOUCH_POS_4: {
                log_printf( &logger, "       >>>   4   <<<       \r\n" );
                break;
            }
            case PROXFUSION3_TOUCH_POS_3: {
                log_printf( &logger, "       >>>   3   <<<       \r\n" );
                break;
            }
            case PROXFUSION3_TOUCH_POS_2: {
                log_printf( &logger, "       >>>   2   <<<       \r\n" );
                break;
            }
            case PROXFUSION3_TOUCH_POS_1: {
                log_printf( &logger, "       >>>   1   <<<       \r\n" );
                break;
            }
            default: {
                Delay_ms ( 10 );
                break;
            }
        }
        
        Delay_ms ( 10 );
    } else {
        Delay_ms ( 10 );
    }
}

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.
