loraDIO引脚中断不起作用

主控芯片STM32L151,利用SPI驱动lora模块，现在发现不触发中断，下边先是配置引脚

GPIO_InitTypeDef GPIO_InitStructure;

__HAL_RCC_GPIOB_CLK_ENABLE( ); GPIO_InitStructure.Pin = GPIO_PIN_4; ///DIO1 PB4 GPIO_InitStructure.Pull = GPIO_NOPULL; GPIO_InitStructure.Mode = GPIO_MODE_IT_RISING; GPIO_InitStructure.Speed = GPIO_SPEED_HIGH; HAL_GPIO_Init(GPIOB, &GPIO_InitStructure );

HAL_NVIC_SetPriority(EXTI4_IRQn, 10, 0); HAL_NVIC_EnableIRQ(EXTI0_IRQn);

/DIO0引脚中断/ void EXTI4_IRQHandler(void) { printf("0\r\n"); uint16_t irqRegs;

if(HAL_GPIO_EXTI_GET_IT(GPIO_PIN_4) != RESET) { printf("0-1\r\n"); HAL_GPIO_EXTI_CLEAR_IT(GPIO_PIN_4);

irqRegs = SX126xGetIrqStatus( );SX126xClearIrqStatus( IRQ_RADIO_ALL );

printf("0-2\r\n"); if( ( irqRegs & IRQ_TX_DONE ) == IRQ_TX_DONE ) { //!< Update operating mode state to a value lower than \ref MODE_STDBY_XOSC SX126xSetOperatingMode( MODE_STDBY_RC ); LoraTxDoneCallback(); printf("1"); }

if( ( irqRegs & IRQ_RX_DONE ) == IRQ_RX_DONE ){ if( RxContinuous == false ) { ///!< Update operating mode state to a value lower than \ref MODE_STDBY_XOSC SX126xSetOperatingMode( MODE_STDBY_RC ); /// WORKAROUND - Implicit Header Mode Timeout Behavior, see DS_SX1261-2_V1.2 datasheet chapter 15.3 /// RegRtcControl = @address 0x0902 SX126xWriteRegister( 0x0902, 0x00 ); /// RegEventMask = @address 0x0944 SX126xWriteRegister( 0x0944, SX126xReadRegister( 0x0944 ) | ( 1 << 1 ) ); /// WORKAROUND END } SX126xGetPayload( RadioRxPayload, &Radiosize , 255 ); SX126xGetPacketStatus( &RadioPktStatus ); LoraRxDoneCallback(); printf("2");}if( ( irqRegs & IRQ_CRC_ERROR ) == IRQ_CRC_ERROR ){ if( RxContinuous == false ) { //!< Update operating mode state to a value lower than \ref MODE_STDBY_XOSC SX126xSetOperatingMode( MODE_STDBY_RC ); } LoraRxErrorCallback(); printf("3");}if( ( irqRegs & IRQ_CAD_DONE ) == IRQ_CAD_DONE ){ //!< Update operating mode state to a value lower than \ref MODE_STDBY_XOSC SX126xSetOperatingMode( MODE_STDBY_RC ); LoraCadDoneCallback(); printf("4");}if( ( irqRegs & IRQ_RX_TX_TIMEOUT ) == IRQ_RX_TX_TIMEOUT ){ if( SX126xGetOperatingMode( ) == MODE_TX ) { SX126xSetOperatingMode( MODE_STDBY_RC ); LoraTxTimeoutCallback( ); printf("5"); } else if( SX126xGetOperatingMode( ) == MODE_RX ) { SX126xSetOperatingMode( MODE_STDBY_RC ); LoraRxTimeoutCallback( ); printf("6"); }}if( ( irqRegs & IRQ_HEADER_ERROR ) == IRQ_HEADER_ERROR ){ if( RxContinuous == false ) { //!< Update operating mode state to a value lower than \ref MODE_STDBY_XOSC SX126xSetOperatingMode( MODE_STDBY_RC ); } LoraRxTimeoutCallback( ); printf("7");}

} }

可能是那些原因呢，有什么排除办法
