Click library

• Author : MikroE Team
• Date : Nov 2019.
• Type : I2C type

Software Support

We provide a library for the Color6 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Color6 Click driver.

Standard key functions :

• Config Object Initialization function.

  void color6_cfg_setup ( color6_cfg_t *cfg );

• Initialization function.

  COLOR6_RETVAL color6_init ( color6_t ctx, color6_cfg_t cfg );

• Click Default Configuration function.

  void color6_default_cfg ( color6_t *ctx );

Example key functions :

• This function write one byte in register.

  void color6_write_byte ( color6_t *ctx, uint8_t reg, uint8_t r_data );

• This function reads one byte data from register.

  uint8_t color6_read_byte ( color6_t *ctx, uint8_t reg );

• The measurement result is available as TEMP of the output result registers.

  float color6_get_temperature ( color6_t *ctx );

Examples Description

Reads values from the X / Y / Z channel and converts to ee (input light irradiance regarding to the photodiode�s area within the conversion time interval) data.

The demo application is composed of two sections :

Application Init

Initializes driver init and configuration chip for measurement.

void application_init ( void )
{
    log_cfg_t log_cfg;
    color6_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.

    color6_cfg_setup( &cfg );
    COLOR6_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    color6_init( &color6, &cfg );

    color6_software_reset( &color6 );
    color6_default_cfg ( &color6 );
    color6_go_to_measurement_mode( &color6 );
}

Application Task

Reads values from the X / Y / Z channel and converts to ee (input light irradiance regarding to the photodiode�s area within the conversion time interval) data. This data logs on USB UART every 2 seconds.

void application_task ( void )
{
    x_data = color6_read_data( &color6, COLOR6_MREG_MEASUREMENT_X_CHANNEL );
    log_printf( &logger, " Channel X :  %d ", x_data );

    ee_data = color6_converting_to_ee( COLOR6_MREG_MEASUREMENT_X_CHANNEL, x_data);
    log_printf( &logger, " Ee X channel data:   %f ", ee_data );

    y_data = color6_read_data( &color6, COLOR6_MREG_MEASUREMENT_Y_CHANNEL );
    log_printf( &logger, " Channel Y :  %d ", y_data );

    ee_data = color6_converting_to_ee( COLOR6_MREG_MEASUREMENT_Y_CHANNEL, y_data);
    log_printf( &logger, " Ee Y channel data:   %f ", ee_data );

    z_data = color6_read_data( &color6, COLOR6_MREG_MEASUREMENT_Z_CHANNEL );
    log_printf( &logger, " Channel Z :  %d ", z_data );

    ee_data = color6_converting_to_ee( COLOR6_MREG_MEASUREMENT_Z_CHANNEL, z_data);
    log_printf( &logger, " Ee Z channel data:   %f ", ee_data );

    temperature = color6_getTemperature( &color6 );
    log_printf( &logger, " Temperature :  %f ", temperature );

    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.Color6

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.
