Posted on May 17, 2011 at 12:56Hi,
I need to configure one of the timers of this STM32 board, for
purpose of delay of 10 seconds.
I used TIM1.
I don't know which values ,I should put in the initial structure,
I try many values but I didn't get more than 2 seconds delay.
Moreover, which flag I should use to recognize when the time over?
I am using this init:
TIM_TimeBaseStructure.TIM_Prescaler = 30000;
TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
TIM_TimeBaseStructure.TIM_Period = 0x270F;
TIM_TimeBaseStructure.TIM_ClockDivision = 0x0;
TIM_TimeBaseStructure.TIM_RepetitionCounter = 0x0;
TIM_TimeBaseInit(TIM1, &TIM_TimeBaseStructure);
/* Channel 1 Configuration in Timing mode TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_Timing;
TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
TIM_OCInitStructure.TIM_OutputNState = TIM_OutputNState_Disable;
TIM_OCInitStructure.TIM_Pulse = 0x0;
TIM_OC1Init(TIM1, &TIM_OCInitStructure);
after that I
enable :
TIM_ITConfig(TIM1, TIM_IT_Update, ENABLE);
TIM_Cmd(TIM1, ENABLE);
I we will be grateful if you could help me,please .
example ,or explain how to calculate it.
Thanks in Advance,
Idan.
