Color 3 Click

Color 3 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 example demonstrates the use of Color 3 Click board by reading data from RGBC channels and converting them to HSL color and displaying those data as well as the detected color name on the USB UART.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Color3

Example Key Functions

• color3_cfg_setup Config Object Initialization function.

void color3_cfg_setup ( color3_cfg_t *cfg ); 

• color3_init Initialization function.

err_t color3_init ( color3_t *ctx, color3_cfg_t *cfg );

• color3_get_rgbc_data This function reads data from 4 channels (Red, Green, Blue, Clear).

err_t color3_get_rgbc_data ( color3_t *ctx, color3_channels_t *channels );

• color3_rgbc_to_hsl This function converts RGBC (red, green, blue, clear) to HSL (hue, saturation, lightness) color value.

void color3_rgbc_to_hsl ( color3_t *ctx, color3_channels_t *rgbc, color3_hsl_t *hsl );

• color3_get_color This function returns the color name flag from the input HSL color.

uint8_t color3_get_color ( color3_hsl_t *hsl );

Application Init

Initializes the driver and performs the Click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;
    color3_cfg_t cfg;

    /** 
     * 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.
    color3_cfg_setup( &cfg );
    COLOR3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    color3_init( &color3, &cfg );
    Delay_ms ( 100 );

    color3_set_default_settings( &color3 );
    Delay_ms ( 1000 );

    log_printf( &logger, "-----------------\r\n" );
    log_printf( &logger, " Color 3  Click  \r\n" );
    log_printf( &logger, "-----------------\r\n" );
}

Application Task

Reads the values of all channels and converts them to HSL color and displays those data as well as the detected color name on the USB UART every 500ms approximately.

void application_task ( void )
{
    color3_channels_t rgbc;
    if ( COLOR3_OK == color3_get_rgbc_data ( &color3, &rgbc ) )
    {
        color3_hsl_t hsl;
        color3_rgbc_to_hsl ( &color3, &rgbc, &hsl );
        log_printf ( &logger, "\r\n Red: %u\r\n", rgbc.red );
        log_printf ( &logger, " Green: %u\r\n", rgbc.green );
        log_printf ( &logger, " Blue: %u\r\n", rgbc.blue );
        log_printf ( &logger, " Clear: %u\r\n", rgbc.clear );
        log_printf ( &logger, " Hue: %.1f deg\r\n", hsl.hue );
        log_printf ( &logger, " Saturation: %.1f %%\r\n", hsl.saturation );
        log_printf ( &logger, " Lightness: %.1f %%\r\n", hsl.lightness );
        log_printf ( &logger, " Dominated color: " );

                break;
            }
            case COLOR3_MAGENTA_COLOR:
            {
                log_printf ( &logger, "MAGENTA\r\n" );
                break;
            }
            case COLOR3_WHITE_COLOR:
            {
                log_printf ( &logger, "WHITE\r\n" );

                break;
            }
            default:
            {
                log_printf ( &logger, "UNKNOWN\r\n" );
                break;
            }
        }

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.
