6.3 Time Management 6.3.1 CoGetOSTime() Function Prototype: U64 CoGetOSTime(void); Description: Obtain the current system time. Parameters: None Returns: The current system tick number. Example Usage: #include "CCRTOS.h" void TaskN (void *pdata) { U64 ostime; ... ostime = CoGetOSTime(); ... } Note: None 6.3.2 CoTickDelay() Function Prototype: StatusType CoTickDelay ( U32 ticks ); Description: Delay the task for a specified system tick number. Parameters: [IN] ticks The number of the system tick number to be delayed Returns: E_CALL, Called in the ISR. E_OK, Execute correctly. 58
Example Usage: #include "CCRTOS.h" void TaskN (void *pdata) { } StatusType result; ... result= CoTickDelay(15); if(result != E_OK) { } { if(result == E_CALL) } ... // Delay 15 system ticks printf("TickDelay cannot been called in ISR !\n"); Note: Once calling TickDelay(), the current task will change from the running state(TASK_RUNNING)to the waiting state (TASK_WAITING). Then it will be inserted into the delay list and delay for the specified system ticks. 6.3.3 CoResetTaskDelayTick() Function Prototype: StatusType CoResetTaskDelayTick Description: ( ); OS_TID U32 taskID, ticks Reset the delayed system ticks of the designated task. Parameters: [IN] taskID ID of the designated task [IN] ticks Returns: The delayed system ticks to be reset to E_INVALID_ID, E_NOT_IN_DELAY_LIST, E_OK, ID is invalid. The designated task isn’t in the delay list. Execute correctly. 59
