/* Define various build options for the ThreadX port. The application should either make changes
here by commenting or un-commenting the conditional compilation defined OR supply the defines
though the compiler's equivalent of the -D option.
For maximum speed, the following should be defined:
TX_MAX_PRIORITIES 32
TX_DISABLE_PREEMPTION_THRESHOLD
TX_DISABLE_REDUNDANT_CLEARING
TX_DISABLE_NOTIFY_CALLBACKS
TX_NOT_INTERRUPTABLE
TX_TIMER_PROCESS_IN_ISR
TX_REACTIVATE_INLINE
TX_DISABLE_STACK_FILLING
TX_INLINE_THREAD_RESUME_SUSPEND
TX_DISABLE_ERROR_CHECKING
For minimum size, the following should be defined:
TX_MAX_PRIORITIES 32
TX_DISABLE_PREEMPTION_THRESHOLD
TX_DISABLE_REDUNDANT_CLEARING
TX_DISABLE_NOTIFY_CALLBACKS
TX_NO_FILEX_POINTER
TX_NOT_INTERRUPTABLE
TX_TIMER_PROCESS_IN_ISR
Of course, many of these defines reduce functionality and/or change the behavior of the
system in ways that may not be worth the trade-off. For example, the TX_TIMER_PROCESS_IN_ISR
results in faster and smaller code, however, it increases the amount of processing in the ISR.
In addition, some services that are available in timers are not available from ISRs and will
therefore return an error if this option is used. This may or may not be desirable for a
given application. */
