STM32F103C8T6如何驱动L6362A

L6362A是一款高速半桥驱动器，它可以用来驱动MOSFET和IGBT等开关器件。要驱动L6362A，首先需要使用STM32F103C8T6的IO口来控制L6362A的使能和PWM信号。

下面是一个简单的示例代码，可以通过STM32F103C8T6的PWM输出控制L6362A的半桥输出，实现电机的控制。

#include "stm32f1xx.h"

#define PWM_PERIOD 1000

void Init_PWM(void)
{
    RCC->APB2ENR |= RCC_APB2ENR_TIM1EN; // Enable timer1 clock
    RCC->APB2ENR |= RCC_APB2ENR_AFIOEN; // Enable alternate function clock

    // Configure PA8 as alternate function push-pull output
    GPIOA->CRH &= ~(GPIO_CRH_CNF8 | GPIO_CRH_MODE8);
    GPIOA->CRH |= GPIO_CRH_CNF8_1 | GPIO_CRH_MODE8;

    // Configure PA9 as alternate function push-pull output
    GPIOA->CRH &= ~(GPIO_CRH_CNF9 | GPIO_CRH_MODE9);
    GPIOA->CRH |= GPIO_CRH_CNF9_1 | GPIO_CRH_MODE9;

    TIM1->ARR = PWM_PERIOD - 1; // Set PWM period
    TIM1->CCMR1 |= TIM_CCMR1_OC1PE | TIM_CCMR1_OC1M_1 | TIM_CCMR1_OC1M_2 | TIM_CCMR1_OC2PE | TIM_CCMR1_OC2M_1 | TIM_CCMR1_OC2M_2; // Configure PWM mode 1 on channels 1 and 2
    TIM1->CCER |= TIM_CCER_CC1E | TIM_CCER_CC2E; // Enable capture/compare on channels 1 and 2
    TIM1->BDTR |= TIM_BDTR_MOE | TIM_BDTR_AOE; // Enable main output and automatic output enable
    TIM1->CR1 |= TIM_CR1_CEN; // Enable timer1
}

void Set_PWM(int16_t pwm)
{
    if (pwm > PWM_PERIOD / 2) pwm = PWM_PERIOD / 2;
    if (pwm < -PWM_PERIOD / 2) pwm = -PWM_PERIOD / 2;

    if (pwm >= 0)
    {
        TIM1->CCR1 = pwm;
        TIM1->CCR2 = 0;
    }
    else
    {
        TIM1->CCR1 = 0;
        TIM1->CCR2 = -pwm;
    }
}

void Init_GPIO(void)
{
    RCC->APB2ENR |= RCC_APB2ENR_IOPAEN; // Enable GPIOA clock

    // Configure PA10 as push-pull output
    GPIOA->CRH &= ~(GPIO_CRH_CNF10 | GPIO_CRH_MODE10);
    GPIOA->CRH |= GPIO_CRH_MODE10;
}

void Set_Enable(int enable)
{
    if (enable)
        GPIOA->BSRR = GPIO_BSRR_BS10; // Set PA10
    else
        GPIOA->BSRR = GPIO_BSRR_BR10; // Reset PA10
}

int main(void)
{
    Init_GPIO();
    Init_PWM();
    Set_Enable(1);

    while (1)
    {
        Set_PWM(500);
        delay_ms(1000);
        Set_PWM(-500);
        delay_ms(1000);
    }
}

在上述代码中，使用了STM32F103C8T6的定时器1的PWM输出和GPIO口控制L6362A的使能信号。需要注意的是，在使用L6362A进行电机控制时，需要对电机的相序进行正确的控制，以避免电机逆转或损坏。
