Tilt 3 Click

Tilt 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.

Example Description

This example demonstrates the use of Tilt 3 Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Tilt3

Example Key Functions

• tilt3_cfg_setup Config Object Initialization function.

void tilt3_cfg_setup ( tilt3_cfg_t *cfg );

• tilt3_init Initialization function.

err_t tilt3_init ( tilt3_t *ctx, tilt3_cfg_t *cfg );

• tilt3_enable_switch This function enables the tilt switch by setting the EN pin to the high logic state.

void tilt3_enable_switch ( tilt3_t *ctx );

• tilt3_disable_switch This function disables the tilt switch by setting the EN pin to the low logic state.

void tilt3_disable_switch ( tilt3_t *ctx );

• tilt3_get_switch_state This function returns the INT pin logic state which indicates the tilt switch state.

uint8_t tilt3_get_switch_state ( tilt3_t *ctx );

Application Init

Initializes the driver and enables the tilt switch.

void application_init ( void )
{
    log_cfg_t log_cfg;      /**< Logger config object. */
    tilt3_cfg_t tilt3_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 );
    Delay_ms ( 100 );
    log_info( &logger, " Application Init " );

    // Click initialization.
    tilt3_cfg_setup( &tilt3_cfg );
    TILT3_MAP_MIKROBUS( tilt3_cfg, MIKROBUS_1 );
    if ( DIGITAL_OUT_UNSUPPORTED_PIN == tilt3_init( &tilt3, &tilt3_cfg ) ) 
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }
    
    tilt3_enable_switch( &tilt3 );
    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 = tilt3_get_switch_state ( &tilt3 );
    if ( tilt3_switch_state != state )
    {
        tilt3_switch_state = state;
        
        if ( TILT3_SWITCH_ON == tilt3_switch_state )
        {
            log_printf( &logger, " Tilt switch ON!\r\n\n" );
        }
        else
        {
            log_printf( &logger, " Tilt switch OFF!\r\n\n" );
        }
        Delay_ms ( 500 );
    }
}

Note

Tilt switches OFF at an angle of 60 degrees minimum and switches ON at the horizontal position (up to 10 degrees). The tilt LED will turn ON when the tilt switch is OFF.

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.
