写一段STM32单片机控制步进电机正转、停止、反转代码

使用STM32单片机控制步进电机正转、停止、反转代码可以用如下代码： //正转
GPIO_SetBits(GPIOA, GPIO_Pin_11);
GPIO_ResetBits(GPIOA, GPIO_Pin_12);
//停止
GPIO_ResetBits(GPIOA, GPIO_Pin_11);
GPIO_ResetBits(GPIOA, GPIO_Pin_12);
//反转
GPIO_ResetBits(GPIOA, GPIO_Pin_11);
GPIO_SetBits(GPIOA, GPIO_Pin_12);

帮我写一个使用stm32控制步进电机正反转的代码

好的，以下是使用stm32控制步进电机正反转的代码：

#include "stm32f10x.h"

#define DIR_PIN GPIO_Pin_
#define STEP_PIN GPIO_Pin_1

void delay_us(uint32_t us)
{
uint32_t i;
for(i=;i<us*8;i++);
}

int main(void)
{
GPIO_InitTypeDef GPIO_InitStructure;
TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
TIM_OCInitTypeDef TIM_OCInitStructure;

RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);
RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM2, ENABLE);

GPIO_InitStructure.GPIO_Pin = DIR_PIN | STEP_PIN;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_Init(GPIOA, &GPIO_InitStructure);

TIM_TimeBaseStructure.TIM_Period = 100 - 1;
TIM_TimeBaseStructure.TIM_Prescaler = 72 - 1;
TIM_TimeBaseStructure.TIM_ClockDivision = ;
TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
TIM_TimeBaseInit(TIM2, &TIM_TimeBaseStructure);

TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
TIM_OCInitStructure.TIM_Pulse = 500 - 1;
TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;
TIM_OC1Init(TIM2, &TIM_OCInitStructure);

TIM_Cmd(TIM2, ENABLE);

while(1)
{
GPIO_SetBits(GPIOA, DIR_PIN);
delay_us(100);
GPIO_ResetBits(GPIOA, STEP_PIN);
delay_us(100);
GPIO_SetBits(GPIOA, STEP_PIN);
delay_us(100);

GPIO_ResetBits(GPIOA, DIR_PIN);
delay_us(100);
GPIO_ResetBits(GPIOA, STEP_PIN);
delay_us(100);
GPIO_SetBits(GPIOA, STEP_PIN);
delay_us(100);

写一段stm32f103c8t6控制步进电机转动一圈的代码

下面是一段stm32f103c8t6控制步进电机转动一圈的代码，假设步进电机使用四相驱动：

#include "stm32f10x.h"

#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 nCount);

int main()
{
    GPIO_InitTypeDef GPIO_InitStructure;
    uint8_t step = 0;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);

    GPIO_InitStructure.GPIO_Pin = STEPPER_PIN1 | STEPPER_PIN2 | STEPPER_PIN3 | STEPPER_PIN4;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    // 步进电机转动一圈需要经过2048个步进
    for (uint16_t i = 0; i < 2048; i++) {
        switch (step) {
            case 0:
                GPIO_SetBits(GPIOA, STEPPER_PIN1);
                GPIO_ResetBits(GPIOA, STEPPER_PIN2 | STEPPER_PIN3 | STEPPER_PIN4);
                break;
            case 1:
                GPIO_SetBits(GPIOA, STEPPER_PIN1 | STEPPER_PIN2);
                GPIO_ResetBits(GPIOA, STEPPER_PIN3 | STEPPER_PIN4);
                break;
            case 2:
                GPIO_SetBits(GPIOA, STEPPER_PIN2 | STEPPER_PIN3);
                GPIO_ResetBits(GPIOA, STEPPER_PIN1 | STEPPER_PIN4);
                break;
            case 3:
                GPIO_SetBits(GPIOA, STEPPER_PIN3 | STEPPER_PIN4);
                GPIO_ResetBits(GPIOA, STEPPER_PIN1 | STEPPER_PIN2);
                break;
        }

        // 延时一段时间
        delay(1000);

        step++;
        if (step > 3) {
            step = 0;
        }
    }

    while(1) {
        // 循环等待
    }
}

void delay(uint32_t nCount)
{
    for(; nCount != 0; nCount--);
}

上面的代码使用了GPIOA0~GPIOA3作为步进电机的控制引脚，每次循环通过切换引脚的电平状态来控制步进电机向前转动一个步进。在每个步进之间需要适当的延时，这里使用了一个简单的循环延时函数`delay`来实现。这段代码可以控制步进电机旋转一圈（360度）。
