Accel 17 Click

Accel 17 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.

Software Support

Example Description

This example showcases ability of the device to read x, y axis orientation.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Accel17

Example Key Functions

• accel17_cfg_setup Config Object Initialization function.

void accel17_cfg_setup ( accel17_cfg_t *cfg );

• accel17_init Initialization function.

err_t accel17_init ( accel17_t *ctx, accel17_cfg_t *cfg );

• accel17_default_cfg Click Default Configuration function.

err_t accel17_default_cfg ( accel17_t *ctx );

• accel17_get_axes_data Accel data reading.

err_t accel17_get_axes_data ( accel17_t *ctx, accel17_axes_t *axes );

• accel17_generic_read Reading function.

err_t accel17_generic_read ( accel17_t *ctx, uint8_t reg, uint8_t *rx_buf, uint8_t rx_len );

• accel17_generic_write Writing function.

err_t accel17_generic_write ( accel17_t *ctx, uint8_t reg, uint8_t tx_data );

Application Init

Initialization of communication modules(I2C, UART), and configures device.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    accel17_cfg_t accel17_cfg;  /**< Click config object. */

    /** 
     * 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.
    accel17_cfg_setup( &accel17_cfg );
    ACCEL17_MAP_MIKROBUS( accel17_cfg, MIKROBUS_1 );
    err_t init_flag = accel17_init( &accel17, &accel17_cfg );
    if ( I2C_MASTER_ERROR == init_flag ) 
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    accel17_default_cfg ( &accel17 );
    Delay_ms ( 1000 );
    log_info( &logger, " Application Task " );
}

Application Task

Reads axis data and calculates it and logs result every 300ms.

void application_task ( void ) 
{
    accel17_axes_t axes;
    accel17_get_axes_data ( &accel17, &axes );
    log_printf( &logger, " > X[degree]: %.2f\r\n > Y[degree]: %.2f\r\n", axes.x, axes.y );
    log_printf( &logger, "*********************************\r\n" );
    Delay_ms ( 300 );
}

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.
