Posted on August 27, 2014 at 13:50Hi All,
i'm having issue on STM32F407 with update events,
sometimes i'm getting IRQ immediatelly after init and sometimes first event is regular update event,
did i missed some initialization step ?
please help me ...
here is my code:
TIM_TimeBaseStructure.TIM_Period = 2000; // ARR
TIM_TimeBaseStructure.TIM_Prescaler = 20999; // PSC ...
TIM_TimeBaseStructure.TIM_ClockDivision = 0; // CR1:CKD TIM67 doesn't have
TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
TIM_TimeBaseInit( TIM7, &TIM_TimeBaseStructure);
TIM_ClearFlag( TIM7, TIM_FLAG_Update );
TIM_ITConfig( TIM7, TIM_IT_Update, ENABLE);
TIM_ClearITPendingBit( TIM7, TIM_IT_Update );
TIM_ClearFlag( TIM7, TIM_FLAG_Update );
TIM_SetCounter( TIM7, 0);
TIM_Cmd( TIM7, ENABLE );
Thanks for all replies,
Kind regards
