Example Usage: #include "CCRTOS.h" #define TASKM_PRIO 11 #define TASKM_STK_SIZE 100 OS_STK TaskMStk[TASKM_STK_SIZE]; OS_TID TaskMId; void TaskM (void *pdata); void TaskN (void *pdata) { ... TaskMId = CoCreateTask (TaskM, (void *)0, TASKM_PRIO, &TaskMStk[TASKM_STK_SIZE-1], TASKM_STK_SIZE); if (TaskMID==E_CREATE_FAIL) { printf("Task Create Failed !\n"); } else { printf("Task ID : %d\n",TaskMId); } ... } void TaskM (void *pdata) { ... } Note: 1) A relevant PCB is distributed when a task is created. 2) A task is in the ready state once being successfully created. 3) If the priority of the current created task is higher than the running task, the system start a task scheduling and distribute the execution time to the current task. 4) The maximum stkSz is 0xfff. CoCreateTaskEx() 48
Function Prototype: OS_TID CoCreateTaskEx Description: ( ); FUNCPtr void* U8 OS_STK* U16 U16 BOOL Create a task and return its ID. Parameters: [IN] task The function which create the task [IN] argv The parameter list of the function [IN] prio [IN] stk The priority of the task task, argv, prio, stk, The starting address of the task stack [IN] stkSz stkSz, timeSlice, isWaitting The size of the task stack(its unit is word) [IN] timeSlice The time slice that the task runs (Once 0 is transferred, set it to the default length of the system.) [IN] isWaitting Task's initial state when being created. If TRUE, task is in TASK_WAITING. Returns: Task ID, Create successfully. -1, Failed to create. Example Usage: 49
