Tilt 4 Click is a compact add-on board designed for reliable tilt detection applications. This board features the RB-231X2, a rolling ball tilt switch from C&K Components, ensuring accurate and safe tilt detection. The RB-231X2 features a compact, shielded design with a detection angle of up to 10° and an operating life of 100,000 cycles. It interfaces with the MCU using only the INT and LED pins, providing real-time interrupt signals and visual tilt indication through a red LED.

Click library

  • Author : Stefan Ilic
  • Date : Nov 2023.
  • Type : GPIO type

Software Support

We provide a library for the Tilt 4 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Tilt 4 Click driver.

Standard 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 );

Example key functions :

  • 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 );

Example Description

This example demonstrates the use of Tilt 4 Click board.

The demo application is composed of two sections :

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 );
    }

}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

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

Additional notes and informations

Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
