我要评论- 定义堆栈
存储task的地方
static StackType_t aos_loop_proc_stack[1024];
- 定义task
static StaticTask_t aos_loop_proc_task;
下面是FreeRTOS里对task的定义
typedef struct xSTATIC_TCB
{
void *pxDummy1;
#if ( portUSING_MPU_WRAPPERS == 1 )
xMPU_SETTINGS xDummy2;
#endif
StaticListItem_t xDummy3[ 2 ];
UBaseType_t uxDummy5;
void *pxDummy6;
uint8_t ucDummy7[ configMAX_TASK_NAME_LEN ];
#if ( ( portSTACK_GROWTH > 0 ) || ( configRECORD_STACK_HIGH_ADDRESS == 1 ) )
void *pxDummy8;
#endif
#if ( portCRITICAL_NESTING_IN_TCB == 1 )
UBaseType_t uxDummy9;
#endif
#if ( configUSE_TRACE_FACILITY == 1 )
UBaseType_t uxDummy10[ 2 ];
#endif
#if ( configUSE_MUTEXES == 1 )
UBaseType_t uxDummy12[ 2 ];
#endif
#if ( configUSE_APPLICATION_TASK_TAG == 1 )
void *pxDummy14;
#endif
#if( configNUM_THREAD_LOCAL_STORAGE_POINTERS > 0 )
void *pvDummy15[ configNUM_THREAD_LOCAL_STORAGE_POINTERS ];
#endif
#if ( configGENERATE_RUN_TIME_STATS == 1 )
uint32_t ulDummy16;
#endif
#if ( configUSE_NEWLIB_REENTRANT == 1 )
struct _reent xDummy17;
#endif
#if ( configUSE_TASK_NOTIFICATIONS == 1 )
uint32_t ulDummy18;
uint8_t ucDummy19;
#endif
#if ( tskSTATIC_AND_DYNAMIC_ALLOCATION_POSSIBLE != 0 )
uint8_t uxDummy20;
#endif
#if( INCLUDE_xTaskAbortDelay == 1 )
uint8_t ucDummy21;
#endif
#if ( configUSE_POSIX_ERRNO == 1 )
int iDummy22;
#endif
} StaticTask_t;
- 初始化系统以及系统线程
system_init();
system_thread_init();
- 创建线程
TaskHandle_t xTaskCreateStatic(
TaskFunction_t pxTaskCode, //任务函数
const char * const pcName, //PC名称/*lint !e971 Unqualified char types are allowed for strings and single characters only. */
const uint32_t ulStackDepth, //堆栈深度，即堆栈大小
void * const pvParameters,// 参数
UBaseType_t uxPriority,//优先级
StackType_t * const puxStackBuffer, //堆buffer地址
StaticTask_t * const pxTaskBuffer )//task buffer地址
涉及的数据类型
>TaskFunction_t void (*TaskFunction_t)( void * ) 即任意函数
> uint32_t long unsigned int
> UBaseType_t long unsigned int
> StackType_t long unsigned int
> StaticTask_t typedef struct xSTATIC_TCB
实例
xTaskCreateStatic(aos_loop_proc, (char*)"event_loop", 1024, NULL, 15, aos_loop_proc_stack, &aos_loop_proc_task);
启动系统调度器
vTaskStartScheduler();
