stm32电机驱动代码

针对STM32电机驱动，需要根据具体的电机类型和驱动方式进行选择和编写代码。以下是一个基于PWM的直流电机驱动代码示例：

#include "stm32f10x.h"

#define PWM_FREQ 10000 // PWM频率
#define PWM_PERIOD (SystemCoreClock / PWM_FREQ) // PWM周期

void TIM_Configuration(void)
{
    TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
    TIM_OCInitTypeDef TIM_OCInitStructure;

    RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM3, ENABLE);

    TIM_TimeBaseStructure.TIM_Period = PWM_PERIOD - 1;
    TIM_TimeBaseStructure.TIM_Prescaler = 0;
    TIM_TimeBaseStructure.TIM_ClockDivision = 0;
    TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
    TIM_TimeBaseInit(TIM3, &TIM_TimeBaseStructure);

    TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
    TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
    TIM_OCInitStructure.TIM_Pulse = 0;
    TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;

    TIM_OC1Init(TIM3, &TIM_OCInitStructure);
    TIM_OC2Init(TIM3, &TIM_OCInitStructure);
    TIM_OC3Init(TIM3, &TIM_OCInitStructure);
    TIM_OC4Init(TIM3, &TIM_OCInitStructure);

    TIM_Cmd(TIM3, ENABLE);
}

void Motor_Configuration(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_AFIO, ENABLE);

    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_6 | GPIO_Pin_7 | GPIO_Pin_8 | GPIO_Pin_9;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &GPIO_InitStructure);
}

void Motor_SetSpeed(int16_t speed)
{
    uint16_t pwm_value;

    if (speed > 0) {
        TIM_SetCompare1(TIM3, 0);
        TIM_SetCompare2(TIM3, speed);
        TIM_SetCompare3(TIM3, 0);
        TIM_SetCompare4(TIM3, 0);
    } else if (speed < 0) {
        TIM_SetCompare1(TIM3, 0);
        TIM_SetCompare2(TIM3, 0);
        TIM_SetCompare3(TIM3, -speed);
        TIM_SetCompare4(TIM3, 0);
    } else {
        TIM_SetCompare1(TIM3, 0);
        TIM_SetCompare2(TIM3, 0);
        TIM_SetCompare3(TIM3, 0);
        TIM_SetCompare4(TIM3, 0);
    }
}

int main(void)
{
    Motor_Configuration();
    TIM_Configuration();

    while (1) {
        Motor_SetSpeed(1000); // 设置电机速度
    }
}
