UV 2 Click

UV 2 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.

Example Description

This app measurement UVA and UVB data and calculate UV index level.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.UV2

Example Key Functions

• uv2_cfg_setup Config Object Initialization function.

void uv2_cfg_setup ( uv2_cfg_t *cfg );

• uv2_init Initialization function.

err_t uv2_init ( uv2_t *ctx, uv2_cfg_t *cfg );

• uv2_default_cfg Click Default Configuration function.

void uv2_default_cfg ( uv2_t *ctx );

• uv2_set_active_force_mode This function set active force mode by write force mode UV_AF bit to config register of VEML6075 sesnor on UV 2 Click.

void uv2_set_active_force_mode ( uv2_t *ctx, uint8_t force_mode );

• uv2_get_uva This function get UVA data by read UVA register value of VEML6075 sesnor on UV 2 Click.

uint16_t uv2_get_uva ( uv2_t *ctx );

• uv2_get_uvb This function get UVB data by read UVB register value of VEML6075 sesnor on UV 2 Click.

uint16_t uv2_get_uvb ( uv2_t *ctx );

Application Init

Initialization device and set default cinfiguration.

void application_init ( void )
{
    log_cfg_t log_cfg;
    uv2_cfg_t cfg;

    uint8_t state_id;

    /** 
     * 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 ----\r\n" );

    //  Click initialization.

    uv2_cfg_setup( &cfg );
    UV2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    uv2_init( &uv2, &cfg );

    Delay_ms ( 100 );

    log_printf( &logger, "------------------------\r\n" );
    log_printf( &logger, "       UV 2  Click      \r\n" );
    log_printf( &logger, "------------------------\r\n" );

    uv2_default_cfg( &uv2 );

    state_id = uv2_check_id( &uv2 );
    
    if ( state_id )
    {
        log_printf( &logger, "       Configured       \r\n" );
    }
    else
    {
        log_printf( &logger, "         ERROR          \r\n" );
    }

    log_printf( &logger, "------------------------\r\n" );
    Delay_ms ( 100 );
}

Application Task

This is a example which demonstrates the use of UV 2 Click board. UV 2 Click communicates with VEML6075 sesnor via I2C by write to register and read from register. This example measurement UVA and UVB data, calculate UV index level and write log. Results are being sent to the Usart Terminal where you can track their changes. All data logs write on usb uart changes for every 2 sec.

void application_task ( void )
{
    uint16_t val_uva;
    uint16_t val_uvb;
    float uv_index;

    val_uva = uv2_get_uva( &uv2 );
    log_printf( &logger, " UVA data = %d \r\n", val_uva );

    val_uvb = uv2_get_uvb( &uv2 );
    log_printf( &logger, " UVB data = %d \r\n", val_uvb );

    uv_index = uv2_get_uv_index( &uv2 );
    log_printf( &logger, " UV Index = %f \r\n", uv_index );

    log_printf( &logger, "------------------------\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

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.
