stm32f4單片機超聲波測距程序出現(xiàn)的警告不修改可以嗎？

下面是我有問題的一段程序，請大家看一下：

void Hcsr04Init()
{
   TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;

GPIO_InitTypeDef GPIO_InitStructure;
RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOA|RCC_AHB1Periph_GPIOB, ENABLE);

GPIO_InitStructure.GPIO_Mode = GPIO_Mode_OUT;//普通輸出模式
  GPIO_InitStructure.GPIO_OType = GPIO_OType_PP;//推挽輸出
  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;//50MHz
  GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_UP;//上拉
GPIO_InitStructure.GPIO_Pin =GPIO_Pin_5;
GPIO_Init(GPIOA, &GPIO_InitStructure);
GPIO_ResetBits(GPIOA,GPIO_Pin_5);

   GPIO_PinAFConfig(GPIOB,GPIO_PinSource6,GPIO_AF_TIM4);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_6;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF;

// GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;

GPIO_Init(GPIOB, &GPIO_InitStructure);
GPIO_ResetBits(GPIOB,GPIO_Pin_6);

      RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM4, ENABLE);

      TIM_DeInit(TIM4);
      TIM_TimeBaseStructure.TIM_Period = (1000-1);
      TIM_TimeBaseStructure.TIM_Prescaler =(84-1);
      TIM_TimeBaseStructure.TIM_ClockDivision=TIM_CKD_DIV1;
      TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
      TIM_TimeBaseInit(TIM4, &TIM_TimeBaseStructure);

      TIM_ClearFlag(TIM4, TIM_FLAG_Update);
      TIM_ITConfig(TIM4,TIM_IT_Update,ENABLE);
      hcsr04_NVIC();
TIM_Cmd(TIM4,DISABLE);
}

void hcsr04_NVIC()
{
         NVIC_InitTypeDef NVIC_InitStructure;
         NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);

         NVIC_InitStructure.NVIC_IRQChannel = TIM4_IRQn;
         NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
         NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
         NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
         NVIC_Init(&NVIC_InitStructure);
}

然后出現(xiàn)兩個警告：

..\HARDWARE\UltrasonicWave\Ultrasonicwave.h(4): warning:  #1295-D: Deprecated declaration Hcsr04Init - give arg types
  void Hcsr04Init();
..\HARDWARE\UltrasonicWave\Ultrasonicwave.h(5): warning:  #1295-D: Deprecated declaration hcsr04_NVIC - give arg types
  void hcsr04_NVIC();

說不推薦使用的聲明hcsr04_NVIC-提供arg類型  不建議使用的聲明Hcsr04Init-提供arg類型

這個我應該怎么修改呢？
