Accel 34 Click

Accel 34 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 demonstrates the use of Accel 34 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.Accel34

Example Key Functions

• accel34_cfg_setup This function initializes Click configuration structure to initial values.

  void accel34_cfg_setup ( accel34_cfg_t *cfg );

• accel34_init This function initializes all necessary pins and peripherals used for this Click board.

  err_t accel34_init ( accel34_t *ctx, accel34_cfg_t *cfg );

• accel34_default_cfg This function executes a default configuration of Accel 34 Click board.

  err_t accel34_default_cfg ( accel34_t *ctx );

• accel34_set_accel_fsr This function sets the accel measurement full scale range.

  err_t accel34_set_accel_fsr ( accel34_t *ctx, uint8_t fsr );

• accel34_get_data This function reads both accelerometer and temperature data from the device.

  err_t accel34_get_data ( accel34_t *ctx, accel34_data_t *data_out );

Application Init

Initializes the driver and performs the Click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  
    accel34_cfg_t accel34_cfg;  

    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );
 
    // Click initialization.
    accel34_cfg_setup( &accel34_cfg );
    ACCEL34_MAP_MIKROBUS( accel34_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == accel34_init( &accel34, &accel34_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( ACCEL34_ERROR == accel34_default_cfg ( &accel34 ) )
    {
        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 )
{
    accel34_data_t meas_data;
    if ( ACCEL34_OK == accel34_get_data ( &accel34, &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.
