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. */ /* Override various options with default values already assigned in tx_port.h.
