使用STM32控制步进电机

本次实验使用的是28BYJ-48，详细介绍步进电机介绍

1.在CudeMX设置IO口作ABCD相输入。

2.其他步骤跟点亮LED灯步骤相同：点亮LED

3.连接好单片机引脚跟驱动板引脚。

4.写入驱动程序。

#define MOTOR_A_L  HAL_GPIO_WritePin(GPIOA, GPIO_PIN_1, GPIO_PIN_RESET)
	
#define MOTOR_B_H  HAL_GPIO_WritePin(GPIOA, GPIO_PIN_2, GPIO_PIN_SET)

#define MOTOR_C_H  HAL_GPIO_WritePin(GPIOA, GPIO_PIN_3, GPIO_PIN_SET)
#define MOTOR_C_L  HAL_GPIO_WritePin(GPIOA, GPIO_PIN_3, GPIO_PIN_RESET)
	
#define MOTOR_D_H  HAL_GPIO_WritePin(GPIOA, GPIO_PIN_4, GPIO_PIN_SET)
#define MOTOR_D_L  HAL_GPIO_WritePin(GPIOA, GPIO_PIN_4, GPIO_PIN_RESET)

void MOTOR_CONTROL(uint8_t direction)
{
	static uint8_t step = 0;
	if(1 == direction){//反转
		if(0 == step) step = 8;
		step--;
	}
	if(0 == step){//步序1
		MOTOR_A_H;
		MOTOR_B_L;
		MOTOR_C_L;
		MOTOR_D_L;
	}else if(1 == step){//步序2
		MOTOR_A_H;

		MOTOR_D_L;
	}else if(2 == step){//步序3

		MOTOR_C_L;
		MOTOR_D_H;
	}
	if(0 == direction){//正转
		step++; if(8 == step) step = 0;
	}
}

void Step_Motor_Start(uint16_t angle, uint8_t direction)//驱动函数angle：角度，direction正反
{
	int i = 0;
	int pulse = (int)((double)(angle/5.625)*64);
	for(i=0; i 
 5.观察到电机按设定的角度旋转。
