32单片机写一段输出具有死区的互补PWM波

下面是一个示例程序，用于在STM32单片机上输出具有死区的互补PWM波。本程序使用的是TIM1定时器，以及PA8和PA9引脚输出PWM信号。死区时间为100个定时器时钟周期，占空比为50%。

#include "stm32f10x.h"

int main(void)
{
    // 初始化定时器1
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_TIM1, ENABLE);
    TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
    TIM_TimeBaseStructure.TIM_Period = 999; // PWM频率为72MHz / (999 + 1) = 72kHz
    TIM_TimeBaseStructure.TIM_Prescaler = 0;
    TIM_TimeBaseStructure.TIM_ClockDivision = 0;
    TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
    TIM_TimeBaseInit(TIM1, &TIM_TimeBaseStructure);

    // 初始化PWM输出通道1和通道2
    TIM_OCInitTypeDef TIM_OCInitStructure;
    TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
    TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
    TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;
    TIM_OCInitStructure.TIM_Pulse = 500; // 初始占空比为50%
    TIM_OC1Init(TIM1, &TIM_OCInitStructure);
    TIM_OC2Init(TIM1, &TIM_OCInitStructure);

    // 初始化死区时间
    TIM_BDTRInitTypeDef TIM_BDTRInitStructure;
    TIM_BDTRInitStructure.TIM_OSSRState = TIM_OSSRState_Enable;
    TIM_BDTRInitStructure.TIM_OSSIState = TIM_OSSIState_Enable;
    TIM_BDTRInitStructure.TIM_LOCKLevel = TIM_LOCKLevel_OFF;
    TIM_BDTRInitStructure.TIM_DeadTime = 100; // 死区时间为100个定时器时钟周期
    TIM_BDTRInitStructure.TIM_Break = TIM_Break_Disable;
    TIM_BDTRInitStructure.TIM_BreakPolarity = TIM_BreakPolarity_High;
    TIM_BDTRInitStructure.TIM_AutomaticOutput = TIM_AutomaticOutput_Enable;
    TIM_BDTRConfig(TIM1, &TIM_BDTRInitStructure);

    // 启动定时器1
    TIM_Cmd(TIM1, ENABLE);

    while (1) {
        // do something
    }
}
