Vibra sense click

Vibra Sense click is a low cost micro shock vibration sensor with a digital output which can be set as an Interrupt (mikroBUS INT pin) An onboard potentiometer lets you set the interrupt threshold.

Click library

• Author : MikroE Team
• Date : Dec 2019.
• Type : GPIO type

Software Support

We provide a library for the VibraSense 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for VibraSense Click driver.

Standard key functions :

• Config Object Initialization function.

  void vibrasense_cfg_setup ( vibrasense_cfg_t *cfg );

• Initialization function.

  VIBRASENSE_RETVAL vibrasense_init ( vibrasense_t ctx, vibrasense_cfg_t cfg );

• Click Default Configuration function.

  void vibrasense_default_cfg ( vibrasense_t *ctx );

Example key functions :

• Check interrupt function.

  uint8_t vibrasense_check_interrupt ( vibrasense_t *ctx ) ;

• Reset vibra sense function.

  void vibrasense_reset ( vibrasense_t *ctx );

Examples Description

This is a example which demonstrates the use of Vibra sense Click board.

The demo application is composed of two sections :

Application Init

Configuring clicks and log objects.

void application_init ( void )
{
    log_cfg_t log_cfg;
    vibrasense_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.

    vibrasense_cfg_setup( &cfg );
    VIBRASENSE_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    vibrasense_init( &vibrasense, &cfg );
    Delay_ms ( 100 );

    log_printf(&logger, "--------------------\r\n");
    log_printf(&logger, "  Vibra sense Click \r\n");
    log_printf(&logger, "--------------------\r\n");

    vibrasense_set_mode( &vibrasense, VIBRASENSE_ENABLE );
    Delay_ms ( 100 );
}

Application Task

It detects vibrations and enables PWM and writes log according to them.

void application_task ( void )
{
    if ( vibrasense_check_interrupt( &vibrasense ) )
    {
        log_printf(&logger, "       TILT !!!     \r\n");
        log_printf(&logger, "--------------------\r\n");
        Delay_ms ( 100 );
    }
} 

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.VibraSense

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
