 * @file main.c
 * @brief LED Driver 19 Click example
 *
 * # Description
 * This library contains API for LED Driver 19 Click driver. 
 * The library initializes and defines the I2C bus drivers to 
 * write the default configuration for a PWM output value 
 * of the out pins.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs default configuration, sets the device
 * in output enabled mode and checks communication by reading device ID.
 *
 * ## Application Task
 * This example demonstrates the use of the LED Driver 19 Click board by 
 * changing PWM values of all channels from maximum to minimum turning 
 * LEDs on and off in the process.
