已经解决。 MX_MotorControl_Init(); --> UI_TaskInit(wConfig,NBR_OF_MOTORS,pMCI,pMCT,s_fwVer); --> MCP_Init(pMCP, (FCP_Handle_t *) & pUSART, & UFCP_Send, & UFCP_Receive, & UFCP_AbortReceive, pDAC, s_fwVer); --> MCP_WaitNextFrame(pHandle); --> pHandle->fFcpReceive(pHandle->pFCP); --> LL_USART_EnableIT_RXNE(pActualHandle->USARTx); 藏得好深。
