這兩個(gè)模塊單獨(dú)運(yùn)行都沒(méi)問(wèn)題，但是把HCSR04測(cè)距程序加到HC05藍(lán)牙程序后，發(fā)送指令測(cè)距程序不運(yùn)行，幫我看看是不是中斷的問(wèn)題，謝謝。
/// 配置USART接收中斷
static void NVIC_Configuration(void)
{
NVIC_InitTypeDef NVIC_InitStructure;
/* Configure the NVIC Preemption Priority Bits */
NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);
/* Enable the USARTy Interrupt */
NVIC_InitStructure.NVIC_IRQChannel = BLT_USART_IRQ;
NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority =1;
NVIC_InitStructure.NVIC_IRQChannelSubPriority = 1;
NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
NVIC_Init(&NVIC_InitStructure);
}
void hcsr04_NVIC(void)
{ NVIC_InitTypeDef NVIC_InitStructure;
NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);
NVIC_InitStructure.NVIC_IRQChannel = TIM8_BRK_TIM12_IRQn ;
NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 3;
NVIC_InitStructure.NVIC_IRQChannelSubPriority = 3;
NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
NVIC_Init(&NVIC_InitStructure);
}
整個(gè)程序就用了這兩個(gè)中斷優(yōu)先級(jí)，這么寫的話，串口能連上藍(lán)牙，但是給指令不測(cè)距。
