Shake2Wake Click

Shake2Wake 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.

• Type : SPI type

Software Support

Example Description

This app shows the capabilities of the Shake2Wake Click by reading values of an accelerometer.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Shake2Wake

Example Key Functions

• shake2wake_cfg_setup Config Object Initialization function.

void shake2wake_cfg_setup ( shake2wake_cfg_t *cfg ); 

• shake2wake_init Initialization function. err_t shake2wake_init ( shake2wake_t *ctx, shake2wake_cfg_t *cfg );

• shake2wake_default_cfg Click Default Configuration function.

void shake2wake_default_cfg ( shake2wake_t *ctx );

• shake2wake_get_lo_res_raw_data This function is used to read 8-bit acceleration data per axis.

void shake2wake_get_lo_res_raw_data ( shake2wake_t *ctx, int8_t *x_val, int8_t *y_val, int8_t *z_val );

• shake2wake_get_raw_data This function is used to read the 3-axis raw data from the accelerometer.

void shake2wake_get_raw_data ( shake2wake_t *ctx, int16_t *x_val, int16_t *y_val, int16_t *z_val )

• shake2wake_read_temperature This function is used to read temperature from an internal sensor.

float shake2wake_read_temperature ( shake2wake_t *ctx );

Application Init

Initalizes device and applies default settings.

void application_init ( void )
{
    log_cfg_t log_cfg;
    shake2wake_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.
    shake2wake_cfg_setup( &cfg );
    SHAKE2WAKE_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    shake2wake_init( &shake2wake, &cfg );
    Delay_ms ( 100 );

    log_printf( &logger, "--------------------------\r\n" );
    log_printf( &logger, "    Shake2Wake  Click     \r\n" );
    log_printf( &logger, "--------------------------\r\n" );

    shake2wake_default_cfg( &shake2wake );
    Delay_ms ( 1000 );
}

Application Task

This is an example that shows the capabilities of the Shake2Wake Click by reading values of an accelerometer and logging them on USART terminal and, in case of an interrupt, it raises voltage on the connector.

void application_task ( void )
{
    float temperature = 0;
    int16_t x_val = 0;
    int16_t y_val = 0;
    int16_t z_val = 0;

    shake2wake_get_raw_data( &shake2wake, &x_val, &y_val, &z_val );
    temperature = shake2wake_read_temperature( &shake2wake );

    log_printf( &logger, "X axis: %d\r\n", x_val );
    log_printf( &logger, "Y axis: %d\r\n", y_val );
    log_printf( &logger, "Z axis: %d\r\n", z_val );
    log_printf( &logger, "Temperature: %.2f degC\r\n", temperature );
    log_printf( &logger, "--------------------------\r\n" );
    Delay_ms ( 1000 );
}

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.
