Click library

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

Software Support

We provide a library for the Shake2Wake 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 Shake2Wake Click driver.

Standard 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 );

Example key functions :

  • 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 );

Examples Description

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

The demo application is composed of two sections :

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 );
}  

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.Shake2Wake

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.

Magneto click carries an AS5048A contactless magnetic angle position sensor. The sensing circuitry relies on the Hall Effect to detect the vector of a nearby magnetic field in a 360º two-dimensional plane parallel to the surface of the chip. AS5048A delivers precise angle measurements down to 0.05º in 14-bit resolution.
