Earthquake Click carries D7S, the world’s smallest high-precision seismic sensor from Omron. The Click is designed to run on either 3.3V or 5V power supply. It communicates with the target MCU over I2C interface, with additional functionality provided by the following pins on the mikroBUS™ line: PWM, INT, CS.

Earthquake Click carries D7S, the world’s smallest high-precision seismic sensor from Omron.
The Click is designed to run on either 3.3V or 5V power supply. It communicates with the target MCU over I2C interface, with additional functionality provided by the following pins on the mikroBUS™ line: PWM, INT, CS.
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.
This library contains API for Earthquake Click driver.
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 );
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 );
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 :
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_printf( &logger, " Earthquake Click \r\n" );
log_printf( &logger, "------------------------\r\n" );
}
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.

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.
