Earthquake Click

Earthquake 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.

Click Library

• Author : MikroE Team
• Date : Feb 2020.
• Type : I2C type

Software Support

Example Description

Intializes I2C module, LOG and GPIO structure, sets INT and PWM pins as input and sets CS pin as output.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Earthquake

Example Key Functions

• earthquake_cfg_setup Config Object Initialization function.

void earthquake_cfg_setup ( earthquake_cfg_t *cfg ); 

• earthquake_init Initialization function.

err_t earthquake_init ( earthquake_t *ctx, earthquake_cfg_t *cfg );

• earthquake_proc_notify Shutoff output function.

uint8_t earthquake_proc_notify ( earthquake_t *ctx );

• earthquake_read_status Read status function.

uint8_t earthquake_read_status ( earthquake_t *ctx );

• earthquake_read_si Read SI function.

uint16_t earthquake_read_si ( earthquake_t *ctx );

Application Init

Intializes of I2C driver and makes initial log.

void application_init ( void )
{
    log_cfg_t log_cfg;
    earthquake_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_info( &logger, "---- Application Init ----" );

    //  Click initialization.
    earthquake_cfg_setup( &cfg );
    EARTHQUAKE_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    earthquake_init( &earthquake, &cfg );
    Delay_ms ( 1000 );
    display_status( earthquake_read_status( &earthquake ) );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    earthquake_clear_memory( &earthquake );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    log_printf( &logger, "------------------------\r\n" );
    log_printf( &logger, "    Earthquake Click    \r\n" );
    log_printf( &logger, "------------------------\r\n" );
}

Application Task

This is an example that shows most of the functions that Earthquake Click has. Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( void )
{
    if ( earthquake_proc_notify( &earthquake ) )
    {
        log_printf( &logger, "  Earthquake detected!  \r\n" );
        log_printf( &logger, "------------------------\r\n" );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );

        for ( cnt = 20; cnt > 0; cnt-- )
        {
            log_printf( &logger, " Status : " );
            display_status( earthquake_read_status( &earthquake ) );

            read_data = earthquake_read_si( &earthquake );
            log_printf( &logger, " Max SI : %d\r\n", read_data );
            log_printf( &logger, "------------------------ \r\n" );
            Delay_ms ( 1000 );
            Delay_ms ( 1000 );
            Delay_ms ( 1000 );
            Delay_ms ( 1000 );
            Delay_ms ( 1000 );
        }

        earthquake_clear_memory( &earthquake );
        log_printf( &logger, " Afterquake  processing \r\n" );
        log_printf( &logger, "     please wait...     \r\n" );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );
        Delay_ms ( 1000 );

        log_printf( &logger, "------------------------\r\n" );
        log_printf( &logger, " Waiting for a quake... \r\n" );
        log_printf( &logger, "------------------------\r\n" );
    }
}

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.
