使用TC78B016FTG和ATmega328在工业和消费应用中实现无刷直流电机的精确管理

 * @file main.c
 * @brief Brushless 10 Click example
 *
 * # Description
 * This example demonstrates the use of the Brushless 10 click board by driving the 
 * motor at different speeds.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration.
 *
 * ## Application Task
 * Controls the motor speed by changing the PWM duty cycle every 2 seconds.
 * The duty cycle ranges from 20% to 100%. Each step will be logged on the USB UART
 * where you can track the program flow.
