- 1/TIM2 is configured as Master Timer:
- - PWM Mode is used
- - The TIM2 Update event is used as Trigger Output
- 2/TIM3 and TIM4 are slaves for TIM2,
- - PWM Mode is used
- - The ITR1(TIM2) 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).
-
- The TIMxCLK is fixed to 72 MHz, the TIM2 counter clock is 72 MHz.
- The Master Timer TIM2 is running at 281.250 KHz and the duty cycle
- is equal to 25%
- The TIM3 is running:
- - At (TIM2 frequency)/ (TIM3 period + 1) = 28.125 KHz and a duty cycle
- equal to TIM3_CCR1/(TIM3_ARR + 1) = 30%
- The TIM4 is running:
- - At (TIM2 frequency)/ (TIM4 period + 1) = 56.250 KHz and a duty cycle
- equal to TIM4_CCR1/(TIM4_ARR + 1) = 60%
