Tilt 4 Click

Tilt 4 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 example demonstrates the use of Tilt 4 Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Tilt4

Example Key Functions

• tilt4_cfg_setup Config Object Initialization function.

void tilt4_cfg_setup ( tilt4_cfg_t *cfg );

• tilt4_init Initialization function.

err_t tilt4_init ( tilt4_t *ctx, tilt4_cfg_t *cfg );

• tilt4_read_int_state This function reads the state of the interrupt pin of Tilt 4 Click board.

uint8_t tilt4_read_int_state ( tilt4_t *ctx );

• tilt4_set_led_state This function sets the LED pin on the selected level level of Tilt 4 Click board.

void tilt4_set_led_state ( tilt4_t *ctx, uint8_t pin_state );

Application Init

Initializes the driver and USB UART logger.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    tilt4_cfg_t tilt4_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.
    tilt4_cfg_setup( &tilt4_cfg );
    TILT4_MAP_MIKROBUS( tilt4_cfg, MIKROBUS_1 );
    if ( DIGITAL_OUT_UNSUPPORTED_PIN == tilt4_init( &tilt4, &tilt4_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

As soon as the tilt switch state changes, it displays a corresponding message on the USB UART.

void application_task ( void ) 
{
    uint8_t state = tilt4_read_int_state ( &tilt4 );
    if ( tilt4_switch_state != state )
    {
        tilt4_switch_state = state;
        
        if ( TILT4_SWITCH_ON == tilt4_switch_state )
        {
            log_printf( &logger, " Tilt switch ON!\r\n\n" );
            tilt4_set_led_state( &tilt4, TILT4_PIN_STATE_HIGH );
        }
        else
        {
            log_printf( &logger, " Tilt switch OFF!\r\n\n" );
            tilt4_set_led_state( &tilt4, TILT4_PIN_STATE_LOW );
        }
        Delay_ms ( 500 );
    }
    
}

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.
