使用TB6605FTG和STM32L073RZ控制各种家用电器中的无刷直流电机

 * @file main.c
 * @brief Brushless 31 Click example
 *
 * # Description
 * This example demonstrates the use of the Brushless 31 Click board by driving the 
 * motor in both directions 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 500 milliseconds.
 * The duty cycle ranges from 80% to 0%. At the minimal speed, the motor switches direction.
 * Each step will be logged on the USB UART where you can track the program flow.
 *
 * @note
 * This Click board is designed for 5V systems but can also be controlled with 3V3 GPIO lines.
 * Ensure your MCU is 5V tolerant on mikroBUS GPIO lines before turning on the power supply.
