Light 2 Click is a compact add-on board designed for accurate and flexible light measurement in various environments. This board features the ISL76682, a high-sensitivity, light-to-digital sensor with an I2C interface from Renesas, made specifically for automotive applications. Key features include a photodiode array that closely mimics the human eye's response, an ADC for flicker rejection, and four selectable light measurement ranges via I2C, enhancing both flexibility and accuracy. With a typical power consumption of 55µA in Standard mode and two power-down modes to minimize energy use, the board is efficient and adaptable to different lighting conditions.
We provide a library for the Light 2 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.
This library contains API for Light 2 Click driver.
light2_cfg_setup
Config Object Initialization function. light2_init
Initialization function. light2_default_cfg
Click Default Configuration function. light2_read_raw_data
This function reads raw data from the ADC of Light 2 Click board. light2_get_cal_const
This function is used to get a calculation constant depending on Light 2 Click board configuration. light2_get_light_data
This function is used to read light data of Light 2 Click board configuration. This example demonstrates the use of Light 2 Click board by measuring
the ambient light level in Lux.
The demo application is composed of two sections :
Initializes the driver and performs the Click default configuration.
Reads the ADC voltage and then calculates the illuminance from it.
The calculated value of illuminance in lux is being displayed on the USB UART approximately once per second.
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.

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.
