UVA Click

UVA 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 : Dec 2021.
• Type : I2C type

Software Support

Example Description

This example demonstrates the use of UVA Click board by reading and displaying the UVA data measurement results.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.UVA

Example Key Functions

• uva_cfg_setup Config Object Initialization function.

void uva_cfg_setup ( uva_cfg_t *cfg );

• uva_init Initialization function.

err_t uva_init ( uva_t *ctx, uva_cfg_t *cfg );

• uva_default_cfg Click Default Configuration function.

err_t uva_default_cfg ( uva_t *ctx );

• uva_read_data This function reads the raw UVA data from registers.

err_t uva_read_data ( uva_t *ctx, uint16_t *uva_data );

• uva_soft_reset This function executes the soft reset command.

err_t uva_soft_reset ( uva_t *ctx );

• uva_write_register This function writes a data byte to the selected register by using I2C serial interface.

err_t uva_write_register ( uva_t *ctx, uint8_t reg, uint8_t data_in );

Application Init

Initializes the driver and applies the Click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    uva_cfg_t uva_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.
    uva_cfg_setup( &uva_cfg );
    UVA_MAP_MIKROBUS( uva_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == uva_init( &uva, &uva_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( UVA_ERROR == uva_default_cfg ( &uva ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Reads the UVA data measurements every 100ms and displays the results on the USB UART.

void application_task ( void )
{
    uint16_t uva_data = 0;
    if ( UVA_OK == uva_read_data ( &uva, &uva_data ) )
    {
        log_printf ( &logger, " UVA data: %u \r\n\n", uva_data );
        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.
