Accel 14 Click

Accel 14 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.

Example Description

This application measures accelermeter data.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Accel14

Example Key Functions

• accel14_cfg_setup Config Object Initialization function.

void accel14_cfg_setup ( accel14_cfg_t *cfg );

• accel14_init Initialization function.

err_t accel14_init ( accel14_t *ctx, accel14_cfg_t *cfg );

• accel14_default_cfg Click Default Configuration function.

void accel14_default_cfg ( accel14_t *ctx );

• accel14_check_accel_data_ready Check accel data ready function.

uint8_t accel14_check_accel_data_ready ( accel14_t *ctx );

• accel14_get_temperature Get temperature function.

float accel14_get_temperature ( accel14_t *ctx );

• accel14_read_accel Read Accel data function.

void accel14_read_accel( accel14_t *ctx, accel14_accel_fs_xl_t *accel_fs );

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 );
    }
}

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.
