c 输出一个STM32 F407 步进电机控制代码

我可以回答这个问题。以下是一个简单的STM32 F407步进电机控制代码：

#include "stm32f4xx.h"

#define STEPPER_PORT GPIOA
#define STEPPER_PIN1 GPIO_Pin_0
#define STEPPER_PIN2 GPIO_Pin_1
#define STEPPER_PIN3 GPIO_Pin_2
#define STEPPER_PIN4 GPIO_Pin_3

void delay(uint32_t time)
{
while(time--);
}

void stepper_init(void)
{
RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOA, ENABLE);

GPIO_InitTypeDef GPIO_InitStruct;
GPIO_InitStruct.GPIO_Pin = STEPPER_PIN1 | STEPPER_PIN2 | STEPPER_PIN3 | STEPPER_PIN4;
GPIO_InitStruct.GPIO_Mode = GPIO_Mode_OUT;
GPIO_InitStruct.GPIO_OType = GPIO_OType_PP;
GPIO_InitStruct.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_InitStruct.GPIO_PuPd = GPIO_PuPd_NOPULL;
GPIO_Init(STEPPER_PORT, &GPIO_InitStruct);
}

void stepper_rotate(uint8_t steps, uint8_t direction)
{
uint8_t i;
uint8_t sequence[4] = {0b0001, 0b0010, 0b0100, 0b1000};

if(direction == 0)
{
for(i = 0; i < steps; i++)
{
GPIO_SetBits(STEPPER_PORT, STEPPER_PIN1);
GPIO_ResetBits(STEPPER_PORT, STEPPER_PIN2 | STEPPER_PIN3 | STEPPER_PIN4);
delay(10000);

GPIO_SetBits(STEPPER_PORT, STEPPER_PIN2);
GPIO_ResetBits(STEPPER_PORT, STEPPER_PIN1 | STEPPER_PIN3 | STEPPER_PIN4);
delay(10000);

GPIO_SetBits(STEPPER_PORT, STEPPER_PIN3);
GPIO_ResetBits(STEPPER_PORT, STEPPER_PIN1 | STEPPER_PIN2 | STEPPER_PIN4);
delay(10000);

GPIO_SetBits(STEPPER_PORT, STEPPER_PIN4);
GPIO_ResetBits(STEPPER_PORT, STEPPER_PIN1 | STEPPER_PIN2 | STEPPER_PIN3);
delay(10000);
}
}
else
{
for(i = 0; i < steps; i++)
{
GPIO_SetBits(STEPPER_PORT, sequence[i%4]);
GPIO_ResetBits(STEPPER_PORT, ~(sequence[i%4]));
delay(10000);
}
}
}

int main(void)
{
stepper_init();

while(1)
{
stepper_rotate(100, 0); // Rotate 100 steps clockwise
stepper_rotate(100, 1); // Rotate 100 steps counterclockwise
}
}
