外部中断里调用AFE4900_Reg_Read程序无法正常运行。在准循环里面调用没有问题。

static uint32_t AFE4900_Reg_Read( unsigned char mRegAddr )

{

    uint32_t masterStatus;

    uint32_t timeOut = 1000UL;

    union VarU32 uAFE4900;

     

    txBuffer[0] = mRegAddr;

    txBuffer[1] = 0;

    txBuffer[2] = 0;

    txBuffer[3] = 0;

   

    /*Write packet to read status */

    Cy_SCB_SPI_WriteArrayBlocking(mSPI_HW, txBuffer, 4 );

   

    do

    {

        masterStatus  = Cy_SCB_SPI_GetSlaveMasterStatus(mSPI_HW);

        //Cy_SysLib_Delay(CY_SCB_WAIT_1_UNIT);

        timeOut--;

       

    }while ( (masterStatus != (CY_SCB_SPI_MASTER_DONE)) && (timeOut > 0UL) );

   

    /* If masterStatus is CY_SCB_SPI_MASTER_DONE check number of bytes in Rx FIFO and set the status. */

    if(masterStatus == CY_SCB_SPI_MASTER_DONE)

    {

        if( 4 == Cy_SCB_SPI_GetNumInRxFifo(mSPI_HW) )

        {

            Cy_SCB_SPI_ReadArray( mSPI_HW, rxBuffer, 4 );

            uAFE4900.mU8[3] = 0;

            uAFE4900.mU8[2] = rxBuffer[1];

            uAFE4900.mU8[1] = rxBuffer[2];

            uAFE4900.mU8[0] = rxBuffer[3];

        }

    }

    else

    {

        handle_error();

    }

   

    /* CLear Master status and Tx FIFO status. */

    Cy_SCB_SPI_ClearSlaveMasterStatus(mSPI_HW, Cy_SCB_SPI_GetSlaveMasterStatus(mSPI_HW));

    Cy_GPIO_Inv( GPIO_PRT13, 7u );   

    sSys.uIR  = AFE4900_Reg_Read( 42 );

    //sSys.uAmbinet = AFE4900_Reg_Read( 42 );

目前问题解决了没有?

可能需要具体分析,中断是否被触发,触发后AFE4900_Reg_Read卡在了什么地方?
