Library Description

Library provides functions for reading color registers from device. Converting data to HSL color data, and automaticly reading predefined colors;

Key functions:

• uint16_t color10_generic_read ( uint8_t cmd_addr ); - Generic read function from device
• float color10_get_color_value ( void ); - Functions for read HSL color value
• uint8_t color10_get_color ( float color_value ); - Functions for detecting colors from HSL value

Examples description

The application is composed of three sections :

• System Initialization - Inicializes I2C module
• Application Initialization - Initialization driver init, checks device ID and sets default configuration
• Application Task - Reads color IR ADC value and then checks for predefined colors with write_color funcion

void application_task ( )
{
    uint16_t read_data;
    float color_data;

    read_data = color10_generic_read( COLOR10_CMD_REG_IR );
    WordToStr( read_data, demo_txt );
    mikrobus_logWrite( " - IR value: ", _LOG_TEXT );
    mikrobus_logWrite( demo_txt, _LOG_LINE );

    mikrobus_logWrite( " - Color: ", _LOG_TEXT );
    write_color( );
    
    mikrobus_logWrite( " *************** ", _LOG_LINE );
    Delay_ms( 1000 );
}

Additional Functions :

• void write_color ( float color_val ) - Reads and gets color HSL value and then checks for the color and logs a few predefined colors

Other mikroE Libraries used in the example:

• I2C
• UART

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.
