14.2.2 Advance HAL Functions
The advanced HAL functions include a level of access that most applications don’t will
never need to access.
int seBeginHighPriority(void)
Description:
Writing and debugging software under the Windows operating system greatly simplifies
the developing process for the S1D13506 evaluation system. One issue which impedes
application programming is that of latency. Time critical operations, performance mea-
surement for instance, are not guaranteed any set amount of processor time.
This function raises the priority of the thread and virtually eliminates the question of
latency for programs running on a Windows platform.
Note
The application should not leave it’s thread running in a high priority state for long peri-
ods of time. As soon as a time critical operation is complete the application should call
seEndHighPriorty().
Parameters:
None.
Return Value:
ERR_OK
If the function completes successfully.
int seEndHighPriority(void)
Description:
The function returns the thread priority of the calling application to normal.
After performing some time critical operation the application should call seEndHighPrior-
ity() to return the thread priority to a normal level.
Parameters:
None.
None.
Return Value:
