STM32F103C8T6设置定时器1和定时器2输出PWM标准库代码

以下是使用标准库代码在STM32F103C8T6上设置定时器1和定时器2输出PWM的示例代码：

#include "stm32f10x.h"

void TIM1_Config(void);
void TIM2_Config(void);

int main(void)
{
    // 初始化定时器1和定时器2
    TIM1_Config();
    TIM2_Config();

    // 启动定时器1和定时器2
    TIM_Cmd(TIM1, ENABLE);
    TIM_Cmd(TIM2, ENABLE);

    while (1)
    {
        // 主循环
    }
}

void TIM1_Config(void)
{
    TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
    TIM_OCInitTypeDef TIM_OCInitStructure;
    GPIO_InitTypeDef GPIO_InitStructure;

    // 使能定时器1和GPIOA的时钟
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_TIM1 | RCC_APB2Periph_GPIOA, ENABLE);

    // 配置GPIOA的引脚为复用推挽输出
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_8;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    // 设置定时器1的预分频值为72，计数频率为1MHz
    TIM_TimeBaseStructure.TIM_Period = 1000 - 1;
    TIM_TimeBaseStructure.TIM_Prescaler = 72 - 1;
    TIM_TimeBaseStructure.TIM_ClockDivision = 0;
    TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
    TIM_TimeBaseInit(TIM1, &TIM_TimeBaseStructure);

    // 配置定时器1通道1的输出比较模式为PWM模式1
    TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
    TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
    TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;
    TIM_OC1Init(TIM1, &TIM_OCInitStructure);

    // 设置定时器1通道1的占空比为50%
    TIM_SetCompare1(TIM1, 500);

    // 使能定时器1
    TIM_Cmd(TIM1, ENABLE);
}

void TIM2_Config(void)
{
    TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
    TIM_OCInitTypeDef TIM_OCInitStructure;
    GPIO_InitTypeDef GPIO_InitStructure;

    // 使能定时器2和GPIOA的时钟
    RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM2, ENABLE);
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);

    // 配置GPIOA的引脚为复用推挽输出
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    // 设置定时器2的预分频值为72，计数频率为1MHz
    TIM_TimeBaseStructure.TIM_Period = 1000 - 1;
    TIM_TimeBaseStructure.TIM_Prescaler = 72 - 1;
    TIM_TimeBaseStructure.TIM_ClockDivision = 0;
    TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
    TIM_TimeBaseInit(TIM2, &TIM_TimeBaseStructure);

    // 配置定时器2通道1的输出比较模式为PWM模式1
    TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
    TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
    TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;
    TIM_OC1Init(TIM2, &TIM_OCInitStructure);

    // 设置定时器2通道1的占空比为50%
    TIM_SetCompare1(TIM2, 500);

    // 使能定时器2
    TIM_Cmd(TIM2, ENABLE);
}

这段代码使用定时器1和定时器2输出PWM信号，使用了GPIOA的引脚8和引脚0作为输出引脚。你可以根据实际需求修改引脚和参数的设置。
