Incorrect UX_PERIODIC_RATE when TX_TIMER_TICKS_PER_SECOND has been set to 1ms

[ifemc]

I have a STMCubeMX project in which I've changed to 1ms tick in ThreadX. This shows the following from printf:

UX_PERIODIC_RATE=100
TX_TIMER_TICKS_PER_SECOND=1000

The attached STM32CubeMX project is ported from Ux_Device_CDC_ACM to run on the STM32H743I-EVAL board and migrated to STM32CubeMX 6.12.1

USART1 is used for printf output. USB_OTG_FS is set up for device cdc.

UX_PERIODIC_RATE is defined in ux_port.h at line 133:

#ifndef UX_PERIODIC_RATE
#define UX_PERIODIC_RATE 100
#endif

It is also defined in ux_api.h at line 893:

#ifndef UX_PERIODIC_RATE
#ifdef TX_TIMER_TICKS_PER_SECOND
#define UX_PERIODIC_RATE (TX_TIMER_TICKS_PER_SECOND)
#else
#define UX_PERIODIC_RATE 100
#endif
#endif

This definition does not have any effect because ux_port.h is included earlier in ux_api.h at line 163:

#include "ux_port.h"

Hi @ifemc 

An internal ticket 196562 is submitted to dedicated team to review definition of UX_PERIODIC_RATE.

/* #define UX_PERIODIC_RATE (TX_TIMER_TICKS_PER_SECOND)*/

In ux_user.h, this line is commented because the UX_PERIODIC_RATE is not entered by User in CubeMX. I was expecting that generated code should have configure it without further modifications.
