- TIM1_CH4 – PA11
- TIM2_CH1 – PA0，PA5
- TIM2_CH2 – PA1，PB3
- TIM2_CH3 – PA2
- TIM2_CH4 – PA3，PB11
- TIM3_CH1 – PA6，PB4，PC6
- TIM3_CH2 – PA7，PB5，PC7
- TIM3_CH3 – PB0，PC8
- TIM3_CH4 – PB1，PC9
- TIM4_CH1 – PB6，PD12
- TIM4_CH2 – PB7，PD13
- TIM4_CH3 – PB8，PD14
- TIM4_CH4 – PB9，PD15
- TIM5_CH1 – PA0
- TIM5_CH2 – PA1

stm32tim1输出pwm

要在STM32的TIM1通道上输出PWM信号，可以按照以下步骤进行配置：

1. 配置TIM1时钟使能，使能GPIO时钟，配置GPIO引脚为复用模式。
2. 配置TIM1为PWM模式，设置计数器自动重载值和预分频器值，设置PWM输出比较值。
3. 配置PWM输出通道的工作模式和极性，使能PWM输出通道。

下面是一个简单的示例代码：

// 使能TIM1时钟和GPIO时钟
RCC_APB2PeriphClockCmd(RCC_APB2Periph_TIM1, ENABLE);
RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOA, ENABLE);

// 配置GPIO引脚为复用模式
GPIO_InitTypeDef GPIO_InitStructure;
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_8;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_100MHz;
GPIO_InitStructure.GPIO_OType = GPIO_OType_PP;
GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_UP;
GPIO_Init(GPIOA, &GPIO_InitStructure);

// 将GPIO引脚与TIM1通道1复用
GPIO_PinAFConfig(GPIOA, GPIO_PinSource8, GPIO_AF_TIM1);

// 配置TIM1为PWM模式
TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
TIM_TimeBaseStructure.TIM_Period = 999; // 计数器自动重载值
TIM_TimeBaseStructure.TIM_Prescaler = 83; // 预分频器值
TIM_TimeBaseStructure.TIM_ClockDivision = TIM_CKD_DIV1;
TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
TIM_TimeBaseInit(TIM1, &TIM_TimeBaseStructure);

// 配置PWM输出比较值
TIM_OCInitTypeDef TIM_OCInitStructure;
TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
TIM_OCInitStructure.TIM_Pulse = 500; // PWM输出比较值
TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;
TIM_OC1Init(TIM1, &TIM_OCInitStructure);

// 配置PWM输出通道的工作模式和极性
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 = 0;
TIM_BDTRInitStructure.TIM_Break = TIM_Break_Disable;
TIM_BDTRInitStructure.TIM_BreakPolarity = TIM_BreakPolarity_Low;
TIM_BDTRInitStructure.TIM_AutomaticOutput = TIM_AutomaticOutput_Enable;
TIM_BDTRConfig(TIM1, &TIM_BDTRInitStructure);

// 使能PWM输出通道
TIM_CCPreloadControl(TIM1, ENABLE);
TIM_Cmd(TIM1, ENABLE);

stm32 tim5输出PWM程序

以下是一个简单的基于STM32 TIM5的PWM输出程序：

#include "stm32f4xx.h"
#include "stm32f4xx_tim.h"
#include "stm32f4xx_rcc.h"

int main(void)
{
   //初始化TIM5
   TIM_TimeBaseInitTypeDef TIM_TimeBaseInitStruct;
   RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM5, ENABLE);
   TIM_TimeBaseInitStruct.TIM_Prescaler = 1000;
   TIM_TimeBaseInitStruct.TIM_CounterMode = TIM_CounterMode_Up;
   TIM_TimeBaseInitStruct.TIM_Period = 100;
   TIM_TimeBaseInitStruct.TIM_ClockDivision = TIM_CKD_DIV1;
   TIM_TimeBaseInitStruct.TIM_RepetitionCounter = 0;
   TIM_TimeBaseInit(TIM5, &TIM_TimeBaseInitStruct);

   //初始化PWM模式
   TIM_OCInitTypeDef TIM_OCInitStruct;
   TIM_OCInitStruct.TIM_OCMode = TIM_OCMode_PWM1;
   TIM_OCInitStruct.TIM_OutputState = TIM_OutputState_Enable;
   TIM_OCInitStruct.TIM_OutputNState = TIM_OutputNState_Disable;
   TIM_OCInitStruct.TIM_Pulse = 50;
   TIM_OCInitStruct.TIM_OCPolarity = TIM_OCPolarity_High;
   TIM_OCInitStruct.TIM_OCNPolarity = TIM_OCNPolarity_Low;
   TIM_OCInitStruct.TIM_OCIdleState = TIM_OCIdleState_Reset;
   TIM_OCInitStruct.TIM_OCNIdleState = TIM_OCNIdleState_Reset;
   TIM_OC1Init(TIM5, &TIM_OCInitStruct);

   //启动TIM5
   TIM_Cmd(TIM5, ENABLE);

   while(1){
      //do something
   }
}

这个程序会在PA0引脚上输出一个50%的占空比的PWM波形，具体的占空比和频率可以通过修改TIM_OCInitStruct中的参数来实现。
