Software Support

We provide a library for the Color Click on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Library Description

The library initializes and defines the I2C bus driver and drivers that offer a choice for writing data in register. The library includes function for configuration chip for measurement, function for reads one color ratio and functions for light color value is received by calculating RGBC value and conversions in HSL value. The user also has the function color_getColor() which checks the color of the light and functions for enable or disable RGB LED.

Key functions :

• void color_setLED(uint8_t red, uint8_t green, uint8_t blue) - Functions for set Led lights
• float color_getColorValue() - Functions for read color value in HSL
• uint8_t color_getColor(float color_value) - Functions for detect colors
• float color_readColorRatio(uint8_t color) - Functions for read color ratio

Examples Description

The application is composed of three sections :

• System Initialization - Initializes I2C module
• Application Initialization - Initializes driver init and configuration chip for measurement
• Application Task - (code snippet) - Read color and check which color is detected by the sensor If the color is detected, the detected color message is logged on the USBUART.

void applicationTask()
{
    colorValue = color_getColorValue();
    isColor = color_getColor(colorValue);

  switch(isColor)
    {
        case 1:
        {
            mikrobus_logWrite("--- Color: ORANGE ", _LOG_LINE);
            break;
        }
        case 2:
        {
            mikrobus_logWrite("--- Color: RED ", _LOG_LINE);
            break;
        }
        case 3:
        {
            mikrobus_logWrite("--- Color: PINK ", _LOG_LINE);
            break;
        }
        case 4:
        {
            mikrobus_logWrite("--- Color: PURPLE ", _LOG_LINE);
            break;
        }
        case 5:
        {
            mikrobus_logWrite("--- Color: BLUE ", _LOG_LINE);
            break;
        }
        case 6:
        {
            mikrobus_logWrite("--- Color: CYAN ", _LOG_LINE);
            break;
        }
        case 7:
        {
            mikrobus_logWrite("--- Color: GREEN ", _LOG_LINE);
            break;
        }
        case 8:
        {
            mikrobus_logWrite("--- Color: YELLOW ", _LOG_LINE);
            break;
        }
        default:
        {
            break;
        }
    }
    Delay_100ms();
}

The full application code, and ready to use projects can be found on our LibStock page.

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.
