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(yīng)該怎么修改呢？
