Timer interrupt not working

[kavinkumar]

Hi was trying to do work with timers in stm32 when i use the timers directy like this i could set the phase voltages correctly .

but when i use the interrupt to set the duty cyles always the phase voltages are zero

how to dynamically set the phase voltages in the timer interrupt

1. Use the code insert feature instead of screen dumps.

2. Is your timer callback ever called? Maybe you started the timer without period interrupt enabled. Use the debugger to check it.

3. If it is called, use the debugger to check the values written to CCRx registers.

1.Okay got it

2. Yes the timer callback is called i could see the elec angle value being updated.

 this is my timer config where should i enable period interrupt
3. is there a way to check the ccr registers in the live expressions?

HAL_TIM_PWM_Start does not turn on any interrupts. Use HAL_TIM_PWM_Start_IT instead if you want callbacks to happen.

You can add TIM1->CCR1 to the live expressions to see it.

its says failed to evaluate expression

Also i'm not using HAL_TIM_PWM_Start i'm using HAL_TIM_Base_Start_IT(&htim1) to start the interrupt @TDK 

EDIT: tried using this 

  HAL_TIM_PWM_Start_IT(&htim1, TIM_CHANNEL_1);
  HAL_TIM_PWM_Start_IT(&htim1, TIM_CHANNEL_2);
  HAL_TIM_PWM_Start_IT(&htim1, TIM_CHANNEL_3);

but still same behaviour maybe if i could see whether if the ccr values changes in the live expression would be helpful to debug
