Use this block to generate edge-aligned Pulse Width Modulation (PWM) signals. The following conditions applies.
| 1. | Up to a maximum number of 4 edge-aligned PWM signals (channels) can be generated per timer. |
| 2. | Each timer has 16-bit counter that determines the PWM period. |
| 3. | PWM period can not be changed during run-time. |
The following table lists available Timer and associated PWM channels together with corresponding MCU Port-Pins.

This block accepts Input Duty Cycle (%) between 0-100 as double values for each generated PWM signal.
This block supports "Enable custom port labels".
PWM signal frequency is determined by the value TIMx_ARR and a duty cycle is determined by the value TIMx_CCRx. The timer's clock is computed as follows:
TIMx_CLK = HCLK/APBxPrescaler
where TIM2,3,4,5,6,7,12,13,14 uses APB1 and TIM1,8,9,10,11 uses APB2.
The timer's auto reload value (TIMx_ARR) that determines the PWM period for each timer is computed from:
TIMx_ARR = (TIMx_CounterClock * PWM_period) - 1
where TIMx_CounterClock = TIMx_CLK / (TIMx_Prescaler + 1).
STM32F4 Target searches for the optimal TIMx_ARR automatically using the following constraints
| 1. | TIMx_Prescaler <= 65535 |
| 2. | TIMx_ARR is as near a whole number as possible, i.e. min(TIMx_ARR - floor(TIMx_ARR)) |
The duty cycle is computed from:
TIMx_CCRx = TIMx_ARR * (Duty Cycle / 100)
