帮我转换成HAL库 void TIM2_PWM_Output(float Duty , uint32_t Frequency) { TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure; TIM_OCInitTypeDef TIM_OCInitStructure; NVIC_InitTypeDef NVIC_InitStructure; GPIO_InitTypeDef GPIO_InitStructure; RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM2, ENABLE); /* GPIOA clock enable */ RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA|RCC_APB2Periph_AFIO ,ENABLE); GPIO_InitStructure.GPIO_Pin = GPIO_Pin_2 ; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; GPIO_Init(GPIOA, &GPIO_InitStructure); NVIC_InitStructure.NVIC_IRQChannel = TIM2_IRQn; NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 1; NVIC_InitStructure.NVIC_IRQChannelSubPriority = 2; NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE; NVIC_Init(&NVIC_InitStructure); /* Time base configuration */ TIM_TimeBaseStructure.TIM_Period = (1000000/Frequency)-1; //ARR = (TIM3 counter clock /Frequency)-1 TIM_TimeBaseStructure.TIM_Prescaler = 71; TIM_TimeBaseStructure.TIM_ClockDivision = 0; TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up; TIM_TimeBaseInit(TIM2, &TIM_TimeBaseStructure); /* PWM1 Mode configuration: Channel3 */ TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1; TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable; TIM_OCInitStructure.TIM_Pulse = ((1000000/Frequency)-1)*Duty; TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High; TIM_OC3Init(TIM2, &TIM_OCInitStructure); TIM_OC3PreloadConfig(TIM2, TIM_OCPreload_Enable); TIM_ARRPreloadConfig(TIM2, ENABLE); /* TIM3 enable counter */ TIM_Cmd(TIM2, ENABLE); }

对应的HAL库代码如下：

#include "stm32f1xx_hal.h"

TIM_HandleTypeDef htim2;

void TIM2_PWM_Output(float Duty , uint32_t Frequency)
{
  GPIO_InitTypeDef GPIO_InitStruct = {0};
  TIM_OC_InitTypeDef sConfigOC = {0};
  TIM_MasterConfigTypeDef sMasterConfig = {0};

  __HAL_RCC_TIM2_CLK_ENABLE();
  __HAL_RCC_GPIOA_CLK_ENABLE();

  GPIO_InitStruct.Pin = GPIO_PIN_2;
  GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
  GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH;
  HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);

  htim2.Instance = TIM2;
  htim2.Init.Prescaler = 71;
  htim2.Init.CounterMode = TIM_COUNTERMODE_UP;
  htim2.Init.Period = (1000000/Frequency)-1;
  htim2.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1;
  HAL_TIM_Base_Init(&htim2);

  sConfigOC.OCMode = TIM_OCMODE_PWM1;
  sConfigOC.Pulse = ((1000000/Frequency)-1)*Duty;
  sConfigOC.OCPolarity = TIM_OCPOLARITY_HIGH;
  sConfigOC.OCFastMode = TIM_OCFAST_DISABLE;
  HAL_TIM_PWM_ConfigChannel(&htim2, &sConfigOC, TIM_CHANNEL_3);

  sMasterConfig.MasterOutputTrigger = TIM_TRGO_RESET;
  sMasterConfig.MasterSlaveMode = TIM_MASTERSLAVEMODE_DISABLE;
  HAL_TIMEx_MasterConfigSynchronization(&htim2, &sMasterConfig);

  HAL_TIM_PWM_Start(&htim2, TIM_CHANNEL_3);
}

注意，此处假设你使用的是STM32F1系列的芯片，需要包含"stm32f1xx_hal.h"头文件。请根据实际情况进行调整。
