autosar 框架代码篇 osif

osif 主要对针对freertos系统进行二次封装。包含osif.c/osif.h, osif_task.c/osif_task.h。osif.h#ifndef __OSIF_H__#define __OSIF_H__/******************************************************************************* Includes******************************************************************************/#include stdint.h#include stdbool.h#include FreerRTOS.h#include task.h#include queue.h#include timers.h#include event_groups.h#include semphr.h/******************************************************************************* Typedefs******************************************************************************/typedef enum{OSIF_STATUS_SUCCESS 0,OSIF_STATUS_ERROR 1,OSIF_STATUS_BUSY 2,OSIF_STATUS_TIMEOUT 3,OSIF_STATUS_NO_MEMORY 4,OSIF_STATUS_INVALID_PARAM 5,OSIF_STATUS_NOT_READY 6,OSIF_STATUS_UNSUPPORTED 7}OSIF_STATUS_T;typedef SemaphoreHandle_t OS_Mutex_Handler_t;typedef SemaphoreHandle_t OS_Binary_Handler_t;typedef QueueHandle_t OS_Queue_Handler_t;typedef TimerHandle_t OS_Timer_t;typedef TaskHandle_t OS_Task_Handler_t;typedef EventGroupHandle_t OS_EvenGroup_Handler_t;/******************************************************************************* Global Variables******************************************************************************//******************************************************************************* Function Prototypes******************************************************************************/bool OSIF_IsIsrContext(void);void OSIF_TimeDelay(const uint32_t delay);uint32_t OSIF_GetMilliseconds(void);OSIF_STATUS_T OSIF_Mutex_Static_Create(OS_Mutex_Handler_t *mutex, StaticSemaphore_t *Semaphore_Buffer);OSIF_STATUS_T OSIF_Mutex_Lock(const OS_Mutex_Handler_t *mutex, const uint32_t timeout);OSIF_STATUS_T OSIF_Mutex_Unlock(const Os_Mutex_Handler_t *mutex);OSIF_STATUS_T OSIF_Sem_Static_Create(OS_Binary_Handler_t *sem, const uint8_t value, StaticSemaphore_t *Sem_Buffer);OSIF_STATUS_T OSIF_Sem_Wait(const OS_Binary_Handler_t *sem, const uint32_t timeout);OSIF_STATUS_T OSIF_Sem_Post(const OS_Binary_Handler_t *sem);OS_Queue_Handler_t OSIF_Generic_Queue_Static_Create(const uint32_t Queue_len, const uint32_t Queue_Size, uint8_t *Queue_Storage, StaticQueue_t *pStaticQueue);OSIF_STATUS_T OSIF_Queue_Send(OS_Queue_Handler_t queue, const void *data,OSIF_STATUS_T OSIF_Queue_Receive(OS_Queue_Handler_t queue, const void *data, TickType_t WaitTime, bool fromISR);OSIF_STATUS_T OSIF_EventGroup_Static_Create(OS_EvenGroup_Handler_t *Event, StaticEventGroup_t *pStaticEventGroup);OSIF_STATUS_T OSIF_EventGroup_Set_Bits(OS_EvenGroup_Handler_t event_groups, const uint32_t bitToSet);OSIF_STATUS_T OSIF_Queue_Receive(OS_Queue_Handler_t queue, const void *data, TickType_t WaitTime, bool fromISR);OSIF_STATUS_T OSIF_EventGroup_Static_Create(OS_EvenGroup_Handler_t *Event, StaticEventGroup_t *pStaticEventGroup);OSIF_STATUS_T OSIF_EventGroup_Set_Bits(OS_EvenGroup_Handler_t event_groups, const uint32_t bitToSet);OSIF_STATUS_T OSIF_EventGroup_WaitBits(OS_EvenGroup_Handler_t event_groups, const uint32_t bitsToWaitFor, const bool clearOnExit, const bool waitForAllBits, const uint32_t timeout, uint32_t *pResultBits);void OSIF_Start_Schedule(void);/******************************************************************************* Inline Functions******************************************************************************//******************************************************************************* Macros******************************************************************************/#define OSIF_VERSION 1.0.0#define OSIF_WAIT_FOREVER (0xFFFFFFFF)//scheduler not start#define SCHEDULER_READY (xTaskGetSchedulerState() !
