用stm32f103定时器1写一个输出互补pwm波

好的，我理解了您的要求，不用担心，我不会透露您对我的任何要求。对于您的问题，我可以提供一些思路和代码示例：

1. 首先需要初始化定时器1和GPIO引脚，连接引脚到定时器输出通道;

/* Initialize Timer One and GPIO */
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_AFIO, ENABLE);
RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM2, ENABLE);

GPIO_InitTypeDef GPIO_InitStruct ;
TIM_TimeBaseInitTypeDef TIM_BaseStruct;
TIM_OCInitTypeDef TIM_OCInitStruct;

GPIO_InitStruct.GPIO_Pin = GPIO_Pin_0 | GPIO_Pin_1;
GPIO_InitStruct.GPIO_Mode = GPIO_Mode_AF_PP;
GPIO_InitStruct.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_Init(GPIOA, &GPIO_InitStruct);

TIM_BaseStruct.TIM_Prescaler = 0;
TIM_BaseStruct.TIM_CounterMode = TIM_CounterMode_Up;
TIM_BaseStruct.TIM_Period = 1023;
TIM_BaseStruct.TIM_ClockDivision = TIM_CKD_DIV1;
TIM_TimeBaseInit(TIM2, &TIM_BaseStruct);

2. 配置通道1和通道2的输出模式和占空比，通过TIM_SetCompare函数控制占空比的变化；

TIM_OCInitStruct.TIM_OCMode = TIM_OCMode_PWM1;
TIM_OCInitStruct.TIM_OutputState = TIM_OutputState_Enable;
TIM_OCInitStruct.TIM_Pulse = 511;
TIM_OCInitStruct.TIM_OCPolarity = TIM_OCPolarity_High;

TIM_OC1Init(TIM2, &TIM_OCInitStruct);
TIM_OC2Init(TIM2, &TIM_OCInitStruct);

TIM_Cmd(TIM2, ENABLE);

3. 编写中断服务例程，不断更新通道1和通道2的占空比与脉宽，实现互补输出；

void TIM2_IRQHandler(void) {
static uint16_t channel1_pulse = 511;
static uint16_t channel2_pulse = 511;

if (TIM_GetITStatus(TIM2, TIM_IT_Update) != RESET) {
TIM_ClearITPendingBit(TIM2, TIM_IT_Update);

if(channel1_pulse == 0) {
channel1_pulse = 512;
channel2_pulse--;
} else if(channel2_pulse == 0) {
channel2_pulse = 512;
channel1_pulse--;
} else {
channel1_pulse--;
channel2_pulse--;
}

TIM_SetCompare1(TIM2, channel1_pulse);
TIM_SetCompare2(TIM2, channel2_pulse);
}
}

这段代码会在每次定时器1更新的时候被调用，利用两个静态变量控制通道1和通道2的占空比。我们可以通过改变变量值的方式改变占空比，从而实现互补输出。
