Macro __HAL_TIM_SET_Compare does not work

Trying to adjust the PWM period value using the macro 

__HAL_TIM_SET_COMPARE(&htim4,TIM_CHANNEL_3,299);

but it does not work.

However the macro 

__HAL_TIM_SET_AUTORELOAD(&htim4, 599);

works fine.

why the __HAL_TIM_SET_COMPARE does not work ?.

The board I am using is NUCLEO-F401RE with CUBE-MX generated project on Truestudio.

Solution

  • I had similar issues with this macro, and would opt instead for:

    htim4.Instance->CCR3=299;

    Supposing you want to set the capture and compare register of channel three for htim4 to 299 to modify your PWM duty cycle.
