好的,以下是基于STM32 HAL库的28BYJ-48步进电机驱动代码,包含正转和反转功能以及速度控制:
```c
#include "stm32f1xx_hal.h"
#define STEPPER_PINS_NUM 4
GPIO_TypeDef* Stepper_GPIO_Port[STEPPER_PINS_NUM] = {GPIOA, GPIOA, GPIOA, GPIOA};
uint16_t Stepper_GPIO_Pin[STEPPER_PINS_NUM] = {GPIO_PIN_0, GPIO_PIN_1, GPIO_PIN_2, GPIO_PIN_3};
int8_t Stepper_Sequence[8][STEPPER_PINS_NUM] =
{
{ 1, 0, 0, 0 },
{ 1, 1, 0, 0 },
{ 0, 1, 0, 0 },
{ 0, 1, 1, 0 },
{ 0, 0, 1, 0 },
{ 0, 0, 1, 1 },
{ 0, 0, 0, 1 },
{ 1, 0, 0, 1 }
};
void Stepper_Init(void)
{
GPIO_InitTypeDef GPIO_InitStruct = {0};
__HAL_RCC_GPIOA_CLK_ENABLE();
GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
GPIO_InitStruct.Pull = GPIO_NOPULL;
GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;
for(int i = 0; i < STEPPER_PINS_NUM; i++)
{
GPIO_InitStruct.Pin = Stepper_GPIO_Pin[i];
HAL_GPIO_Init(Stepper_GPIO_Port[i], &GPIO_InitStruct);
}
}
void Stepper_SetSpeed(uint16_t speed)
{
// 根据需要设置步进电机的速度
}
void Stepper_Turn(uint8_t direction, uint16_t steps)
{
uint8_t step_idx = 0;
uint8_t sequence_idx = 0;
if(direction == 0) // 反转
{
sequence_idx = 7;
}
for(uint16_t i = 0; i < steps; i++)
{
for(int j = 0; j < STEPPER_PINS_NUM; j++)
{
if(Stepper_Sequence[sequence_idx][j] == 1)
{
HAL_GPIO_WritePin(Stepper_GPIO_Port[j], Stepper_GPIO_Pin[j], GPIO_PIN_SET);
}
else
{
HAL_GPIO_WritePin(Stepper_GPIO_Port[j], Stepper_GPIO_Pin[j], GPIO_PIN_RESET);
}
}
step_idx += direction;
sequence_idx += direction;
if(step_idx == 4)
{
step_idx = 0;
}
else if(step_idx == -1)
{
step_idx = 3;
}
if(sequence_idx == 8)
{
sequence_idx = 0;
}
else if(sequence_idx == -1)
{
sequence_idx = 7;
}
HAL_Delay(1); // 此处可以根据需要调整延时时间,以控制步进电机速度
}
}
```
使用时可以先调用`Stepper_Init()`函数进行GPIO初始化,然后调用`Stepper_SetSpeed()`函数设置速度,最后调用`Stepper_Turn()`函数控制步进电机正转或反转。例如,控制步进电机正转100步,速度为500us/步,代码如下:
```c
Stepper_SetSpeed(500); // 设置速度为500us/步
Stepper_Turn(1, 100); // 控制步进电机正转100步
```
