The Color 15 Click Board™ is a compact add-on board representing an accurate color sensing solution. This board features the CLS-16D24-44-DF8/TR8, a low power, high sensitivity, color light sensor from Everlight Electronics. This Click board™, with an I2C configurable color sensor, senses red, green, blue, white (RGBW), and infrared light and converts them to digital values. The RGBW sensor is designed to reject IR in light sources allowing the device to operate in environments from sunlight to dark rooms. The integrating ADC rejects 50Hz and 60Hz flickers caused by artificial light sources. This Click board™ is suitable for automatic residential and commercial lighting management, contrast enhancement, detection of ambient for backlight control, and more.
The Color 15 Click Board™ is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.
How Does The Color 15 Click Board™ Work?
The Color 15 Click Board™ as its foundation uses the CLS-16D24-44-DF8/TR8, a digital I2C compatible interface color light sensor from Everlight Electronics. It supports parallel output for Red, Green, Blue, White and Infrared light (R, G, B, W, IR) and converts them to a 16-bit digital value (0-65535). This sensor is characterized by high resolution designed to reject IR in light sources allowing the device to operate in environments from sunlight to dark rooms, with a maximum detection lux of 204.679lux. Besides, an integrated ADC rejects 50Hz and 60Hz flickers caused by artificial light sources. It also has stable performance over a wide temperature range of -40°C to 65°C, suitable for measuring the present color light.
The CLS-16D24-44-DF8/TR8 does not require a specific Power-Up sequence but requires a voltage of 1.8V for its interface and logic part to work correctly. Therefore, a small regulating LDO is used, the MAX8511, providing a 1.8V out of both 5V and 3.3V mikroBUS™ power rails.
The Color 15 Click Board™ communicates with MCU using the standard I2C 2-Wire interface with a maximum clock frequency of 400kHz, fully adjustable through software registers. Since the sensor for operation requires a power supply of 3.3V, this Click board™ also features the PCA9306 and SN74LVC1T45 voltage-level translators. The I2C interface bus lines are routed to the voltage-level translators allowing this Click board™ to work with both 3.3V and 5V MCUs properly. Also, it uses an interrupt pin, the INT pin of the mikroBUS™ socket, used when an interrupt occurs to alert the system when the color result crosses upper or lower threshold settings.
The Color 15 Click Board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the communication lines properly. However, the Click board™ comes equipped with a library that contains easy-to-use functions and an example code that can be used, as a reference, for further development.

Software Support
We provide a library for the Color 15 Click Board™ as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
The package can be downloaded/installed directly from NECTO Studio The package Manager (recommended), downloaded from our LibStock™ or found on MikroE Github account.
Library Description

Key functions
-
color15_get_dataThis function reads data from 5 channels (Red, Green, Blue, White, IR). -
color15_rgbw_to_hslThis function converts RGBW (red, green, blue, white) to HSL (hue, saturation, lightness) color value. -
color15_get_colorThis function returns the color name flag from the input HSL color.
Example Description
This example demonstrates the use of the Color 15 Click Board™ by reading data from 5 channels and converting them to HSL color and displaying those data as well as the detected color name on the USB UART.
