STM32 CAN2 进不了收中断

只看该作者 · 2011-9-27 09:36

各位兄弟，我来求助了，我用到Stm32f107的，我用到CAN2，CAN2可以发，但进不了接收中断，求真像。
相关代码如下：
RCC_APB1PeriphClockCmd(RCC_APB1Periph_CAN2,ENABLE);
。。
void CAN_Configuration(void)
{
CAN_InitTypeDef       CAN_InitStructure;
CAN_FilterInitTypeDef  CAN_FilterInitStructure;

CAN_DeInit(CAN2);
CAN_StructInit(&CAN_InitStructure);

/* CAN cell init */
CAN_InitStructure.CAN_TTCM = DISABLE;
CAN_InitStructure.CAN_ABOM = DISABLE;
CAN_InitStructure.CAN_AWUM = DISABLE;
CAN_InitStructure.CAN_NART = DISABLE;
CAN_InitStructure.CAN_RFLM = DISABLE;
CAN_InitStructure.CAN_TXFP = DISABLE;
CAN_InitStructure.CAN_Mode = CAN_Mode_Normal;
CAN_InitStructure.CAN_SJW = CAN_SJW_1tq;
CAN_InitStructure.CAN_BS1 = CAN_BS1_3tq;
CAN_InitStructure.CAN_BS2 = CAN_BS2_5tq;
CAN_InitStructure.CAN_Prescaler = 4;
CAN_Init(CAN2, &CAN_InitStructure);

/* CAN filter init */
CAN_FilterInitStructure.CAN_FilterNumber=14;
CAN_FilterInitStructure.CAN_FilterMode=CAN_FilterMode_IdMask;
CAN_FilterInitStructure.CAN_FilterScale=CAN_FilterScale_32bit;
CAN_FilterInitStructure.CAN_FilterIdHigh=0;
CAN_FilterInitStructure.CAN_FilterIdLow=0;
  CAN_FilterInitStructure.CAN_FilterMaskIdHigh=0;
CAN_FilterInitStructure.CAN_FilterMaskIdLow=0;
CAN_FilterInitStructure.CAN_FilterFIFOAssignment=0;
CAN_FilterInitStructure.CAN_FilterActivation=ENABLE;
CAN_FilterInit(CAN2, &CAN_FilterInitStructure);

/* transmit */
TxMessage.StdId = 0x321;
  TxMessage.ExtId = 0x01;
  TxMessage.RTR = CAN_RTR_DATA;
  TxMessage.IDE = CAN_ID_STD;
  TxMessage.DLC = 1;
}
。。
void NVIC_Configuration(void)
{
NVIC_InitTypeDef NVIC_InitStructure;

NVIC_PriorityGroupConfig(NVIC_PriorityGroup_0);
NVIC_SetVectorTable(NVIC_VectTab_FLASH, 0x0);
NVIC_InitStructure.NVIC_IRQChannel = CAN2_RX0_IRQn;////
NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0x0;
NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0x1;
NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
NVIC_Init(&NVIC_InitStructure);
}
。。
void CAN2_RX0_IRQHandler(void)
{
//我在这里放个断点，用另一个开发板发送CAN数据，进不了中断。另一个发送的是一定没问题的
   CAN_Receive(CAN2, CAN_FIFO0, &RxMessage);

//
}
