hal_create_thread - Create a HAL thread
int hal_create_thread(const char* name, unsigned long period, int uses_fp)
int hal_thread_delete(const char* name)
name
The name of the thread.
period
The interval, in nanoseconds, between iterations of the thread.
uses_fp
Must be nonzero if a function which uses floating-point will be attached to this thread.
hal_create_thread establishes a realtime thread that will execute one or more HAL functions periodically.
All thread periods are rounded to integer multiples of the hardware timer period, and the timer period is based on the first thread created. Threads must be created in order, from the fastest to the slowest. HAL assigns decreasing priorities to threads that are created later, so creating them from fastest to slowest results in rate monotonic priority scheduling.
hal_delete_thread deletes a previously created thread.
Call only from realtime init code, not from other realtime or non-realtime code.
Returns a HAL status code.
