Accel 23 Click

Accel 23 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.

Click Library

• Author : Stefan Filipovic
• Date : Jul 2025.
• Type : I2C/SPI type

Software Support

Example Description

This example demonstrates the use of the Accel 23 Click board by reading acceleration and temperature data from the onboard 3-axis accelerometer. The measured values are displayed via the UART terminal.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Accel23

Example Key Functions

• accel23_cfg_setup This function initializes Click configuration structure to initial values.

void accel23_cfg_setup ( accel23_cfg_t *cfg );

• accel23_init This function initializes all necessary pins and peripherals used for this Click board.

err_t accel23_init ( accel23_t *ctx, accel23_cfg_t *cfg );

• accel23_default_cfg This function executes a default configuration of Accel 23 Click board.

err_t accel23_default_cfg ( accel23_t *ctx );

• accel23_get_data This function retrieves acceleration and temperature data from the device.

err_t accel23_get_data ( accel23_t *ctx, accel23_data_t *data_out );

Application Init

Initializes the logger and the Click board and applies the default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    accel23_cfg_t accel23_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.
    accel23_cfg_setup( &accel23_cfg );
    ACCEL23_MAP_MIKROBUS( accel23_cfg, MIKROBUS_1 );
    err_t init_flag = accel23_init( &accel23, &accel23_cfg );
    if ( ( I2C_MASTER_ERROR == init_flag ) || ( SPI_MASTER_ERROR == init_flag ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( ACCEL23_ERROR == accel23_default_cfg ( &accel23 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Reads the acceleration values in X, Y, and Z axis as well as the internal temperature, then displays the results on the UART terminal.

void application_task ( void )
{
    accel23_data_t meas_data;
    if ( ACCEL23_OK == accel23_get_data ( &accel23, &meas_data ) )
    {
        log_printf( &logger, " Accel X: %.3f g\r\n", meas_data.accel.x );
        log_printf( &logger, " Accel Y: %.3f g\r\n", meas_data.accel.y );
        log_printf( &logger, " Accel Z: %.3f g\r\n", meas_data.accel.z );
        log_printf( &logger, " Temperature: %.2f degC\r\n\n", meas_data.temperature );
        Delay_ms ( 80 );
    }
}

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.
