UVB Click

UVB 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 Click is ultraviolet sensing board, capable of measuring UV index between 0 to 16. UVB Click supports integrated functions of ultraviolet light sensors.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.UVB

Example Key Functions

• uvb_cfg_setup Config Object Initialization function.

void uvb_cfg_setup ( uvb_cfg_t *cfg );

• uvb_init Initialization function.

err_t uvb_init ( uvb_t *ctx, uvb_cfg_t *cfg );

• uvb_default_cfg Click Default Configuration function.

err_t uvb_default_cfg ( uvb_t *ctx );

• uvb_configuration Configuration register.

void uvb_configuration ( uvb_t *ctx, uint8_t reg, uint8_t cfg );

• uvb_read_byte Read one byte data from register.

uint8_t uvb_read_byte ( uvb_t *ctx, uint8_t reg );

• uvb_get_uv_data Get UVB data.

uint16_t uvb_get_uv_data ( uvb_t *ctx );

Application Init

Initialization driver init, check communication and configuration module for measurement.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    uvb_cfg_t uvb_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.
    uvb_cfg_setup( &uvb_cfg );
    UVB_MAP_MIKROBUS( uvb_cfg, MIKROBUS_1 );
    err_t init_flag = uvb_init( &uvb, &uvb_cfg );
    if ( I2C_MASTER_ERROR == init_flag ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    uvb_default_cfg ( &uvb );
    log_info( &logger, " Application Task " );
    log_printf( &logger, "--------------------------\r\n" );
}

Application Task

Reads UVB data and logs to the USBUART every 1500ms.

void application_task ( void ) 
{
    uvb_data = uvb_get_uv_data( &uvb );

    log_printf( &logger, ">> UVB data: %d\r\n", uvb_data );

    log_printf( &logger, "--------------------------\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 500 );
}

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.
