I need to be able to update the Period for a timer (TIM3) I though it was simple, but no.

I have tried :
else if(TIM_GetITStatus(TIM3, TIM_IT_Update) != RESET)
     ledTimeBaseStructure.TIM_Period = newValue;
     TIM_TimeBaseInit(TIM3, &ledTimeBaseStructure);
     TIM_ClearITPendingBit(TIM3, TIM_IT_Update);

but without any look, the period should be around 1 sek, but it is around 1 – 2 ms.

There must be a simple solution, so I hope any one can help, thanks
