Click library

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

Software Support

We provide a library for the Earthquake 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 Earthquake Click driver.

Standard key functions :

  • earthquake_cfg_setup Config Object Initialization function.

    void earthquake_cfg_setup ( earthquake_cfg_t *cfg ); 
  • earthquake_init Initialization function.

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

Example key functions :

  • 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 );

Examples Description

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

The demo application is composed of two sections :

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" );
    }
}  

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.

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

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.
