Accel 32 Click

Accel 32 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.

• Date : Feb 2025.
• Type : SPI type

Software Support

Example Description

This example demonstrates the use of Accel 32 Click board by reading and displaying the accelerometer data (X, Y, and Z axis) and a temperature measurement in degrees Celsius.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Accel32

Example Key Functions

• accel32_cfg_setup This function initializes Click configuration structure to initial values.

void accel32_cfg_setup ( accel32_cfg_t *cfg );

• accel32_init This function initializes all necessary pins and peripherals used for this Click board.

err_t accel32_init ( accel32_t *ctx, accel32_cfg_t *cfg );

• accel32_default_cfg Click Default Configuration function.

err_t accel32_default_cfg ( accel32_t *ctx );

• accel32_set_accel_fsr This function sets the accel measurement full scale range.

err_t accel32_set_accel_fsr ( accel32_t *ctx, uint8_t fsr );

• accel32_get_data This function reads both accelerometer and temperature data from the device.

err_t accel32_get_data ( accel32_t *ctx, accel32_data_t *data_out );

Application Init

Initializes the driver and performs the Click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    accel32_cfg_t accel32_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.
    accel32_cfg_setup( &accel32_cfg );
    ACCEL32_MAP_MIKROBUS( accel32_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == accel32_init( &accel32, &accel32_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( ACCEL32_ERROR == accel32_default_cfg ( &accel32 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Reads the accelerometer and temperature measurements. The results are displayed on the USB UART every 100 ms.

void application_task ( void )
{
    accel32_data_t meas_data;
    if ( ACCEL32_OK == accel32_get_data ( &accel32, &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: %.1f degC\r\n\n", meas_data.temperature );
        Delay_ms ( 100 );
    }
}

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.
