TouchClamp Click

TouchClamp 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 shows the touch position using TouchClamp Click.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.TouchClamp

Example Key Functions

• touchclamp_cfg_setup Config Object Initialization function.

void touchclamp_cfg_setup ( touchclamp_cfg_t *cfg );

• touchclamp_init Initialization function.

err_t touchclamp_init ( touchclamp_t *ctx, touchclamp_cfg_t *cfg );

• touchclamp_default_cfg Click Default Configuration function.

void touchclamp_default_cfg ( touchclamp_t *ctx );

• touchclamp_get_touch_data Get touch data function.

uint16_t touchclamp_get_touch_data ( touchclamp_t *ctx );

Application Init

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

void application_init ( void )
{
    log_cfg_t log_cfg;
    touchclamp_cfg_t cfg;

    /** 
     * 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, " Application Init \r\n" );

    //  Click initialization.

    touchclamp_cfg_setup( &cfg );
    TOUCHCLAMP_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    touchclamp_init( &touchclamp, &cfg );
    Delay_ms ( 100 );
    
    touchclamp_soft_reset( &touchclamp );
    Delay_ms ( 100 );
    
    touchclamp_default_cfg( &touchclamp );
    Delay_ms ( 100 );
    
    touch_data_old = TOUCHCLAMP_NO_TOUCH;
    
    log_printf( &logger, "-------------------\r\n" );
    log_printf( &logger, " Touch Clamp Click \r\n" );
    log_printf( &logger, "-------------------\r\n" );
}

Application Task

Detect and dispay touch position when the Click is triggered.

void application_task ( void )
{
    touch_data = touchclamp_get_touch_data( &touchclamp );
    
    if ( touch_data_old != touch_data )
    {
        if ( touch_data == TOUCHCLAMP_TOUCH_POSITION_H )
            log_printf( &logger, "  - - - - - - - H\r\n" );
            
        if ( touch_data == TOUCHCLAMP_TOUCH_POSITION_G )
            log_printf( &logger, "  - - - - - - G -\r\n" );
            
        if ( touch_data == TOUCHCLAMP_TOUCH_POSITION_F )
            log_printf( &logger, "  - - - - - F - -\r\n" );
                                                       
        if ( touch_data == TOUCHCLAMP_TOUCH_POSITION_E )                       
            log_printf( &logger, "  - - - - E - - -\r\n" );
                                                       
        if ( touch_data == TOUCHCLAMP_TOUCH_POSITION_D )                       
            log_printf( &logger, "  - - - D - - - -\r\n" );
                                                       
        if ( touch_data == TOUCHCLAMP_TOUCH_POSITION_C )                       
            log_printf( &logger, "  - - C - - - - -\r\n" );
                                                       
        if ( touch_data == TOUCHCLAMP_TOUCH_POSITION_B )                       
            log_printf( &logger, "  - B - - - - - -\r\n" );
                                                       
        if ( touch_data == TOUCHCLAMP_TOUCH_POSITION_A )                       
            log_printf( &logger, "  A - - - - - - -\r\n" );
      
        touch_data_old = touch_data;
    }
}

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.
