使用MCF8316A和ATmega328P实现平稳安静的BLDC电机控制

/*!
 * @file main.c
 * @brief Brushless 33 Click example
 *
 * # Description
 * This example demonstrates the control of an A2212/13T 1000KV motor using
 * the Brushless 33 Click board. The example showcases basic motor operations, including
 * speed adjustments, direction switching, and fault handling. The motor speed is
 * controlled by varying the PWM duty cycle.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the logger and configures the Click board.
 *
 * ## Application Task
 * Adjusts the motor's duty cycle to control its speed, alternating between increasing
 * and decreasing duty values. Fault conditions are checked and resolved to maintain
 * stable operation. Additional motor controls, such as switching direction and braking,
 * are triggered based on the duty cycle limits. Each step will be logged on the USB UART
 * where you can track the program flow.
 *
 * @note
 * The library is configured for an A2212/13T 1000KV motor with a 12V power supply.
