Color 13 click

Color 13 Click is a compact add-on board that measures the subtlest changes in light. This board features the APDS-9999, I2C compatible RGB, proximity detector, and vertical-cavity surface-emitting laser (VCSEL) in one optical module from Broadcom Limited.

Click library

• Author : Luka Filipovic
• Date : Jun 2021.
• Type : I2C type

Software Support

We provide a library for the Color13 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Color13 Click driver.

Standard key functions :

• color13_cfg_setup Config Object Initialization function.

  void color13_cfg_setup ( color13_cfg_t *cfg );

• color13_init Initialization function.

  err_t color13_init ( color13_t *ctx, color13_cfg_t *cfg );

Example key functions :

• color13_get_rgb_ir Read color data from device.

  err_t color13_get_rgb_ir ( color13_t *ctx, color13_color_t *color_data );

• color13_get_als Read lux data from device.

  err_t color13_get_als ( color13_t *ctx, float *als_data );

• color13_get_proximity Read proximity data from device.

  err_t color13_get_proximity ( color13_t *ctx, uint16_t *ps_data );

Example Description

This application showcases ability of click board to read RGB and IR data from device. Also it can be configured to read proximity data and ALS data in lux units.

The demo application is composed of two sections :

Application Init

Initialization of host communication modules (UART, I2C) and additonal pin. Read and check device ID, selects example and configures device for it.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    color13_cfg_t color13_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.
    color13_cfg_setup( &color13_cfg );
    COLOR13_MAP_MIKROBUS( color13_cfg, MIKROBUS_1 );
    err_t init_flag = color13_init( &color13, &color13_cfg );
    if ( I2C_MASTER_ERROR == init_flag ) 
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    uint8_t temp_data = 0;
    init_flag = color13_generic_read( &color13, COLOR13_REG_PART_ID, &temp_data, 1 );
    log_printf( &logger, " > ID: 0x%.2X\r\n", ( uint16_t )temp_data );

    if ( ( COLOR13_OK != init_flag ) && ( COLOR13_ID != temp_data ) )
    {
        log_error( &logger, " ID" );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    //Select example
    example_type = COLOR13_EXAMPLE_RGB;
    color13_generic_write( &color13, COLOR13_REG_MAIN_CTRL, &example_type, 1 );

    if ( COLOR13_EXAMPLE_PS_LS == example_type )
    {
        //Configure proximity data to 11 bit
        color13_generic_read( &color13, COLOR13_REG_PS_MEASRATE, &temp_data, 1 );
        temp_data |= 0x18;
        color13_generic_write( &color13, COLOR13_REG_PS_MEASRATE, &temp_data, 1 );
    }

    Delay_ms ( 1000 );
    log_info( &logger, " Application Task " );
}

Application Task

Depending of selected example in task proximity and als data will be read from device, or it will show ADC value for red, green, blue and ir data from device.

void application_task ( void ) 
{
    switch ( example_type )
    {
        case COLOR13_EXAMPLE_PS_LS:
        {
            color13_proximity_als_example( );
            break;
        }
        case COLOR13_EXAMPLE_RGB:
        {
            color13_rgb_example( );
            break;
        }
        default:
        {
            log_error( &logger, " Select example!" );
            break;
        }
    }
    Delay_ms ( 500 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.Color13

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. UART terminal is available in all MikroElektronika compilers.
