一、显式（Explicit）和隐式（Implicit）

创建两种不同类型的port

1.1 显式模式

1.1.1code

TASK(OsTask_10ms) /* PRQA S 3408, 1503 */ /* MD_Rte_3408, MD_MSR_Unreachable */
{/* call runnable */Runnable11(); /* PRQA S 2987 */ /* MD_Rte_2987 */(void)TerminateTask(); /* PRQA S 3417 */ /* MD_Rte_Os */
} /* PRQA S 6010, 6030, 6050, 6080 */ /* MD_MSR_STPTH, MD_MSR_STCYC, MD_MSR_STCAL, MD_MSR_STMIF */

读写均为操作中间变量,在runnable运行中可以被其他地方赋值改变此中间变量。

#  define Rte_Write_AsrTest_Send_Explicit_test1 Rte_Write_CpApServer_AsrTest_Send_Explicit_test1
#  define Rte_Write_CpApServer_AsrTest_Send_Explicit_test1(data) (Rte_CtApsever_AsrTest_Send_Explicit_test1 = (data), ((Std_ReturnType)RTE_E_OK))
#  define Rte_Write_AsrTest_Send_Explicit_test2 Rte_Write_CpApServer_AsrTest_Send_Explicit_test2
#  define Rte_Write_CpApServer_AsrTest_Send_Explicit_test2(data) (Rte_CtApsever_AsrTest_Send_Explicit_test2 = (data), ((Std_ReturnType)RTE_E_OK))

二、隐式模式

2.1 code

TASK(Appl_Task_10ms_OsCore3) /* PRQA S 3408, 1503 */ /* MD_Rte_3408, MD_MSR_Unreachable */
{EventMaskType ev;for(;;){(void)WaitEvent(Rte_Ev_Cyclic2_Appl_Task_10ms_OsCore3_0_20ms | Rte_Ev_Cyclic_Appl_Task_10ms_OsCore3_0_10ms | Rte_Ev_Cyclic_Appl_Task_10ms_OsCore3_0_20ms | Rte_Ev_Cyclic_Appl_Task_10ms_OsCore3_0_40ms); /* PRQA S 3417 */ /* MD_Rte_Os */(void)GetEvent(Appl_Task_10ms_OsCore3, &ev); /* PRQA S 3417 */ /* MD_Rte_Os */(void)ClearEvent(ev & (Rte_Ev_Cyclic2_Appl_Task_10ms_OsCore3_0_20ms | Rte_Ev_Cyclic_Appl_Task_10ms_OsCore3_0_10ms | Rte_Ev_Cyclic_Appl_Task_10ms_OsCore3_0_20ms | Rte_Ev_Cyclic_Appl_Task_10ms_OsCore3_0_40ms)); /* PRQA S 3417 */ /* MD_Rte_Os */if ((ev & Rte_Ev_Cyclic_Appl_Task_10ms_OsCore3_0_10ms) != (EventMaskType)0){/* START PRE RUNNABLE Appl_Runnable10ms_core0 *//* read implicit data */*(&Rte_Appl_Task_10ms_OsCore3.Rte_RB.Rte_CtAp_Demo_Core0_Appl_Runnable10ms_core0.Rte_AsrTest_recive_Implicit_test1.value) = Rte_CtApsever_AsrTest_Send_Implicit_test1; /* PRQA S 1339, 2982 */ /* MD_Rte_1339, MD_Rte_2982 */*(&Rte_Appl_Task_10ms_OsCore3.Rte_RB.Rte_CtAp_Demo_Core0_Appl_Runnable10ms_core0.Rte_AsrTest_recive_Implicit_test2.value) = Rte_CtApsever_AsrTest_Send_Implicit_test2; /* PRQA S 1339, 2982 */ /* MD_Rte_1339, MD_Rte_2982 *//* STOP PRE RUNNABLE Appl_Runnable10ms_core0 *//* call runnable */Runnabletest_server(); /* PRQA S 2987 */ /* MD_Rte_2987 */(); /* PRQA S 2987 */ /* MD_Rte_2987 */}
