pwm整流器c语言代码

以下是一个简单的基于STM32的PWM整流器的C语言代码，你可以根据需要进行修改和适配：

#include "stm32f10x.h"

#define PWM_DUTY_CYCLE 1000 // PWM占空比

void GPIO_Configuration(void);
void TIM_Configuration(void);
void PWM_Configuration(void);

int main(void)
{
    GPIO_Configuration();
    TIM_Configuration();
    PWM_Configuration();
    
    while (1)
    {
        // 你的代码逻辑
    }
}

void GPIO_Configuration(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);
    
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AIN;
    GPIO_Init(GPIOA, &GPIO_InitStructure);
}

void TIM_Configuration(void)
{
    TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
    RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM2, ENABLE);
    
    TIM_TimeBaseStructure.TIM_Period = 1999;
    TIM_TimeBaseStructure.TIM_Prescaler = 71;
    TIM_TimeBaseStructure.TIM_ClockDivision = TIM_CKD_DIV1;
    TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
    TIM_TimeBaseInit(TIM2, &TIM_TimeBaseStructure);
}

void PWM_Configuration(void)
{
    TIM_OCInitTypeDef TIM_OCInitStructure;
    TIM_Cmd(TIM2, ENABLE);
    
    TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
    TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
    TIM_OCInitStructure.TIM_Pulse = PWM_DUTY_CYCLE - 1;
    TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;
    TIM_OC1Init(TIM2, &TIM_OCInitStructure);
    TIM_OC1PreloadConfig(TIM2, TIM_OCPreload_Enable);
}

这个代码使用了STM32的TIM模块来生成PWM波形，并且使用了TIM2的通道1来控制输出，通过修改PWM_DUTY_CYCLE的值可以改变占空比。
