Library Description

The library contains basic functions for working with the UVC click.

Key functions:

• uint16_t uvc_read_raw_data( ) - Read 12bit raw data
• float uvc_get_voltage( ) - Calculate voltage
• float uvc_calculate_power( float voltage ) - Calculate power

Examples description

The application is composed of three sections :

• System Initialization - Initializes I2C module
• Application Initialization - Initializes driver init
• Application Task - Reads sensor raw data and calculating voltage and power data.

void application_task ( )
{
    uint16_t raw_data;
    float voltage;
    float power;
    char demo_text[ 20 ];
    
    raw_data = uvc_read_raw_data();
    IntToStr( raw_data, demo_text );
    mikrobus_logWrite( "Raw data: ", _LOG_TEXT );
    mikrobus_logWrite( demo_text, _LOG_LINE );
    
    voltage = uvc_get_voltage();
    FloatToStr( voltage, demo_text );
    mikrobus_logWrite( "Voltage: ", _LOG_TEXT );
    mikrobus_logWrite( demo_text, _LOG_TEXT );
    mikrobus_logWrite( " mV", _LOG_LINE );

    power = uvc_calculate_power( voltage );
    FloatToStr( power, demo_text );
    mikrobus_logWrite( "Power: ", _LOG_TEXT );
    mikrobus_logWrite( demo_text, _LOG_TEXT );
    mikrobus_logWrite( " mW/cm2", _LOG_LINE );

    mikrobus_logWrite( "----------------------", _LOG_LINE );
    Delay_ms( 1500 );
}

Other mikroE Libraries used in the example:

• I2C library
• Conversions

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
