Accel 14 Click

Accel 14 Click is digital acceleration and vibration sensor Click board™. It features an ultra-wide bandwidth, low-noise, 3-axis digital vibration sensor, labeled as IIS3DWB, from STMicroelectronics. This Click board™ allows selectable full-scale acceleration measurements in ranges of ±2 g, ±4 g, ±8, and ±16 g in three axes, and it’s capable of measuring accelerations with a bandwidth up to 6 kHz with an output data rate of 26.7 kHz.

Click library

• Author : MikroE Team
• Date : Jul 2020.
• Type : SPI type

Software Support

We provide a library for the Accel14 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 Accel14 Click driver.

Standard key functions :

• Config Object Initialization function.

  void accel14_cfg_setup ( accel14_cfg_t *cfg );

• Initialization function.

  ACCEL14_RETVAL accel14_init ( accel14_t ctx, accel14_cfg_t cfg );

• Click Default Configuration function.

  void accel14_default_cfg ( accel14_t *ctx );

Example key functions :

• Check accel data ready function.

  uint8_t accel14_check_accel_data_ready ( accel14_t *ctx );

• Get temperature function.

  float accel14_get_temperature ( accel14_t *ctx );

• Read Accel data function

  void accel14_read_accel ( accel14_t ctx, accel14_accel_fs_xl_t accel_fs );

Examples Description

This application measures accelermeter data.

The demo application is composed of two sections :

Application Init

SPI, check device ID, sets default configuration, also write log.

void application_init ( void )
{
    log_cfg_t log_cfg;
    accel14_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.

    accel14_cfg_setup( &cfg );
    ACCEL14_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    accel14_init( &accel14, &cfg );

    Delay_ms ( 100 );

    log_printf( &logger, "   Driver init done   \r\n" );
    log_printf( &logger, "--------------------- \r\n" );
    log_printf( &logger, " Communication check  \r\n" );

    if ( accel14_check_communication( &accel14 ) == ACCEL14_CHECK_ID_SUCCESS )
    {
        log_printf( &logger, "       SUCCESS        \r\n" );
        log_printf( &logger, "--------------------- \r\n" );
    }
    else
    {
        log_printf( &logger, "        ERROR         \r\n" );
        log_printf( &logger, "   Reset the device   \r\n" );
        log_printf( &logger, "--------------------- \r\n" );
        for ( ; ; );
    }

    log_printf( &logger, " Set default config.  \r\n" );
    log_printf( &logger, "--------------------- \r\n" );
    accel14_default_cfg( &accel14 );
    Delay_ms ( 100 );

    log_printf( &logger, "  Acceleration data:  \r\n" );
    log_printf( &logger, "--------------------- \r\n" );
}

Application Task

This is an example which demonstrates the use of Accel 14 Click board. Measured and display Acceleration data for X-axis, Y-axis and Z-axis. Results are being sent to the Usart Terminal where you can track their changes. All data logs write on USB uart changes for every 1 sec.

void application_task ( void )
{
    data_ready_flag = accel14_check_accel_data_ready( &accel14 );
    Delay_ms ( 10 );

    if ( data_ready_flag == ACCEL14_NEW_DATA_AVAILABLE )
    {
        accel14_get_data ( &accel14, &accel_data );

        log_printf( &logger, "  Accel X : %d \r\n", accel_data.x );
        log_printf( &logger, "  Accel Y : %d \r\n", accel_data.y );
        log_printf( &logger, "  Accel Z : %d \r\n", accel_data.z );
        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.Accel14

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.
