ProxFusion Click

ProxFusion 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 Description

This demo-app reads and displays touch events using ProxFusion Click.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.ProxFusion

Example Key Functions

• proxfusion_cfg_setup Config Object Initialization function.

void proxfusion_cfg_setup ( proxfusion_cfg_t *cfg ); 

• proxfusion_init Initialization function.

err_t proxfusion_init ( proxfusion_t *ctx, proxfusion_cfg_t *cfg );

• proxfusion_default_cfg Click Default Configuration function.

err_t proxfusion_default_cfg ( proxfusion_t *ctx );

• proxfusion_get_touch Touch event

uint8_t proxfusion_get_touch ( proxfusion_t *ctx );

• proxfusion_set_system_reg Sets system register

err_t proxfusion_set_system_reg ( proxfusion_t *ctx, uint8_t cfg );

• proxfusion_set_event_reg Selecting events

err_t proxfusion_set_event_reg ( proxfusion_t *ctx, uint8_t cfg );

Application Init

Configuring Clicks and log objects. Settings the Click in the default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    proxfusion_cfg_t proxfusion_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.
    proxfusion_cfg_setup( &proxfusion_cfg );
    PROXFUSION_MAP_MIKROBUS( proxfusion_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == proxfusion_init( &proxfusion, &proxfusion_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( PROXFUSION_ERROR == proxfusion_default_cfg ( &proxfusion ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
} 

Application Task

Checks if a new touch event occurred and prints(logs) event message on usbuart.

void application_task ( void )
{
    uint8_t touch = proxfusion_get_touch( &proxfusion );
    if ( 1 == touch )
    {
        log_printf( &logger, " Touch button 1 is pressed\r\n" );
    }
    else if ( 2 == touch )
    {
        log_printf( &logger, " Touch button 2 is pressed\r\n" );
    }
    else if ( 3 == touch )
    {
        log_printf( &logger, " Both touch buttons are pressed\r\n" );
    }
    Delay_ms ( 100 );
}

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.
