freemodbus_slave-master-freertos-stm32's Issues

porttimer.c 问题

void vMBPortTimersEnable(void * this)
{
TIM_HandleTypeDef *p = (TIM_HandleTypeDef *)this;
__HAL_TIM_SET_COUNTER(p, 0);
HAL_TIM_Base_Start_IT((TIM_HandleTypeDef *)this);
}
开启定时器前先清清零定时器，否则从机接收数据总是出错

eMBMasterPoll函数代码错误

  case EV_MASTER_FRAME_RECEIVED:
         eStatus = p->peMBMasterFrameReceiveCur(this, &ucRcvAddress, &ucMBFrame, &usLength);
         /* Check if the frame is for us. If not ,send an error process event. */
         if ((eStatus == MB_ENOERR) && (ucRcvAddress == p->ucMBMasterDestAddress))
         {
             goto EV_MASTER_EXECUTE_LABLE;
         }
         else
         {
             p->eMBMasterCurErrorType = EV_ERROR_RECEIVE_DATA;
             goto EV_MASTER_ERROR_PROCESS_LABLE;
         }
         break;

     case EV_MASTER_EXECUTE:
     EV_MASTER_EXECUTE_LABLE:
         ucMBFrame = (UCHAR *)&(p->ucMasterRTUSndBuf[MB_SER_PDU_PDU_OFF]);
         ucFunctionCode = ucMBFrame[MB_PDU_FUNC_OFF];
         eException = MB_EX_ILLEGAL_FUNCTION;

代码中 ucMBFrame = (UCHAR *)&(p->ucMasterRTUSndBuf[MB_SER_PDU_PDU_OFF]); 不应该出现这行
