Color 17 Click

Color 17 Click is a compact add-on board representing an accurate color-sensing solution. This board features the OPT4048, a high-speed precision tristimulus XYZ color sensor from Texas Instruments. The sensor has four sensing channels and uses precision optical filters to mimic the normal vision of the human eye. The OPT4048 also has 12 configurable conversion times that range from 600μs up to 800ms, with measurements that can be read synchronously or asynchronously. It is not excessively sensitive to micro-shadows and the small particles on the optical surface.

Click library

  • Author : Nenad Filipovic
  • Date : Apr 2023.
  • Type : I2C type

Software Support

We provide a library for the Color 17 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 Color 17 Click driver.

Example Description

This library contains API for the Color 17 Click driver. This example displays CCT data, Light intensity level and the light color names.

The demo application is composed of two sections :

Application Init

Initialization of I2C module and log UART. After driver initialization, default settings turn on the device.

void application_init ( void )
{
log_cfg_t log_cfg;
color17_cfg_t color17_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
color17_cfg_setup( &color17_cfg );
COLOR17_MAP_MIKROBUS( color17_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == color17_init( &color17, &color17_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( COLOR17_ERROR == color17_default_cfg ( &color17 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
Delay_ms ( 100 );
}

Application Task

This example demonstrates the use of the Color 17 Click board™. Reads and displays the correlated color temperature and Light intensity level. This example also detects and displays the light color names. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void )
{
if ( COLOR17_OK == color17_get_cct( &color17, &cct, &light_intensity ) )
{
log_printf( &logger, " CCT: %.2f\r\n", cct );
log_printf( &logger, " LIL: %.2f\r\n", light_intensity );
log_printf( &logger, " - - - - - - - - - - - \r\n" );
}
log_printf( &logger, " ----------------------\r\n" );
Delay_ms ( 1000 );
}

Note

Color detection is obtained based on the analysis of calculate the correlated color temperature (CCT) data and the CIE 1931 chromaticity diagram. For more details please refer to the “OPT4048 High Speed High Precision Tristimulus XYZ Color Sensor datasheet” OPT4048 datasheet.

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.Color17

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.
