使用 ALI781 和 STM32F446RE 提升您的空间美感

/*!
 * @file 
 * @brief Leddriver6 Click example
 *
 * # Description
 * This application designed to be used in tunable Smart Connected Lighting applications.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes I2C driver and PWM driver for the LED driver 6 control.
 *
 * ## Application Task
 * This is an example that demonstrates the use of the LED Driver 6 Click board.
 * This example shows the automatic control LED light intensity,
 * the first intensity of light is rising and then the intensity of light is falling.
 * Results are being sent to the Usart Terminal where you can track their changes.
