使用 MCP8063 和 STM32G474RE 释放无刷直流电机的潜力。

/*!
 * @file 
 * @brief Brushless 4 Click example
 * 
 * # Description
 * This click has many features for driving a wide range of small to medium BLDC motors.
 * It provides the rotor position digital output, via the FG pin, routed to the mikroBUS INT pin. 
 * 
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the GPIO driver 
 * and configures the PWM peripheral for controlling the speed of the motor.
 * 
 * ## Application Task  
 * This is an example that demonstrates the use of a Brushless 4 Click board.
 * Brushless 4 Click communicates with the register via the PWM interface.  
 * Increases and decreasing the speed of the motor demonstrate speed control.
 * Results are being sent to the Usart Terminal where you can track their changes.
