- 1/TIM1 is configured as Master Timer:
- - PWM Mode is used
- - The TIM1 Update event is used as Trigger Output
-
- 2/TIM3 and TIM4 are slaves for TIM1,
- - PWM Mode is used
- - The ITR0(TIM1) is used as input trigger for both slaves
- - Gated mode is used, so starts and stops of slaves counters
- are controlled by the Master trigger output signal(update event).
-
- TIM1CLK = 72 MHz, Prescaler = 0, TIM1 counter clock = 72 MHz
- The Master Timer TIM1 is running at:
- TIM1 frequency = TIM1 counter clock / (TIM1_Period + 1) = 281.250 KHz
- and the duty cycle is equal to:
- TIM1_CCR1/(TIM1_ARR + 1) = 50%
-
- The TIM3 is running:
- - At (TIM1 frequency)/((TIM3 period + 1)* (Repetion_Counter+1)) = 18.750 KHz
- and a duty cycle equal to TIM3_CCR1/(TIM3_ARR + 1) = 33.3%
- The TIM4 is running:
- - At (TIM1 frequency)/((TIM4 period + 1)* (Repetion_Counter+1)) = 28.125 KHz
- and a duty cycle equal to TIM4_CCR1/(TIM4_ARR + 1) = 50%
