Library Description

The library covers all the necessary functions to control Accel 14 click board. Library performs a standard SPI interface communication.

Key functions:

• void accel14_default_config ( void ) - Set default configuration function.
• void accel14_get_data ( accel14_accel_t *p_accel_data ) - Get Accel data function.
• float accel14_get_temperature ( void ) - Get temperature function.

Examples description

The application is composed of three sections :

• System Initialization - Initializes SPI and start to write log.
• Application Initialization - Initialization driver enables - SPI, check device ID, sets default configuration, also write log.
• Application Task - (code snippet) 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 ( )
{
    data_ready_flag = accel14_check_accel_data_ready( );
    Delay_ms( 10 );
    
    if ( data_ready_flag == ACCEL14_NEW_DATA_AVAILABLE )
    {
        accel14_get_data ( &accel_data );

        mikrobus_logWrite( "  Accel X : ", _LOG_TEXT );
        IntToStr( accel_data.x, log_text );
        mikrobus_logWrite( log_text, _LOG_LINE );

        mikrobus_logWrite( "  Accel Y : ", _LOG_TEXT );
        IntToStr( accel_data.y, log_text );
        mikrobus_logWrite( log_text, _LOG_LINE );

        mikrobus_logWrite( "  Accel Z : ", _LOG_TEXT );
        IntToStr( accel_data.z, log_text );
        mikrobus_logWrite( log_text, _LOG_LINE );

        mikrobus_logWrite( "---------------------", _LOG_LINE );
        Delay_ms( 1000 );
    }
}

Other mikroE Libraries used in the example:

• SPI
• UART
• Conversions

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.
