Detailed Description

Color 4 Click example.

Description

This library contains API for the Color 4 Click driver. This driver provides the functions for the sensor configuration and for reading RGBW and ambient light data from the device. This example displays RGBW data, Ambient light level, CCT data 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.

Application Task

This example demonstrates the use of the Color 4 Click board™. Reads and displays the results of the RGBW, Ambient light level, calculate the correlated color temperature. This example also detects and displays the light color names. Results are being sent to the UART Terminal, where you can track their changes.

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 “Designing the VEML6040 into an Application” application note (www.vishay.com/doc?84331).

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 LOG_MAP_USB_UART macro definition for detailed explanation.
