TIM3 初始化PA6

根据引用\[1\]中提供的信息，TIM3的初始化可以参考以下代码：

#include "stm32f10x.h"

void TIM3_Init(void)
{
    // 使能TIM3时钟
    RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM3, ENABLE);

    // 定时器配置
    TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
    TIM_TimeBaseStructure.TIM_Period = 999; // 设置计数器自动重装值
    TIM_TimeBaseStructure.TIM_Prescaler = 7199; // 设置预分频值
    TIM_TimeBaseStructure.TIM_ClockDivision = TIM_CKD_DIV1; // 设置时钟分频
    TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up; // 设置计数器模式为向上计数
    TIM_TimeBaseInit(TIM3, &TIM_TimeBaseStructure);

    // 启动定时器
    TIM_Cmd(TIM3, ENABLE);

    // 配置GPIO引脚
    GPIO_InitTypeDef GPIO_InitStructure;
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_6;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    // 配置TIM3通道1为PWM输出模式
    TIM_OCInitTypeDef TIM_OCInitStructure;
    TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
    TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
    TIM_OCInitStructure.TIM_Pulse = 500; // 设置占空比
    TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;
    TIM_OC1Init(TIM3, &TIM_OCInitStructure);
    TIM_OC1PreloadConfig(TIM3, TIM_OCPreload_Enable);
}

以上代码是TIM3的初始化代码，其中PA6引脚被配置为TIM3的通道1输出。你可以根据自己的需求修改占空比等参数。
