Is there a way in MX2 to enable/disable timer freezing during debugging?

Hello,

Is there a setting in MX2 to enable/disable timer freezing during debugging? If not, what HAL APIs can be used for this purpose?

Thank you,

Gil

Hello,

It is not available in MX2. It needs to be configured manually in the debug register, DBGMCU_APB1LFZR, in particular. I invite you to check the reference manual, page 2543.

Hello,

You need to use DBGMCU block and call call __HAL_DBGMCU_FREEZE_TIMx() to freeze the timer during the debug.

If you re using TIM1 so call  __HAL_DBGMCU_FREEZE_TIM1().

DBGMCU_APBxy register:

Edit:

For HAL2 use HAL_DBGMCU_TIMx_Freeze() where x is the timer number.
