#ifndef TX_USER_H

/* 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
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. */

to tx_port.h for descriptions on each of these options. */

value is 10ms (i.e. 100 ticks, defined in tx_api.h), but may be replaced by a port-specific
version in tx_port.h or here.
Note: the actual hardware timer value may need to be changed (usually in tx_initialize_low_level). */

the .bss section prior to ThreadX running, the define can be used to eliminate unnecessary
clearing of ThreadX global variables. */

#define TX_DISABLE_REDUNDANT_CLEARING
*/
/* Determine if no timer processing is required. This option will help eliminate the timer
processing when not needed. The user will also have to comment out the call to
tx_timer_interrupt, which is typically made from assembly language in
