PWM: Three signals at different duty cycles

The program generates three signals each of them with a different duty cycle value but the same period since all of them comes from channels form the timer TIM1. Notice the sConfig.Pulse can not exceed the maximum value of TimHandle.Init.Period.

    /* Config PWM channel with a 75% duty cycle */
    sConfig.Pulse = 1000;
    HAL_TIM_PWM_ConfigChannel( &TimHandle, &sConfig, TIM_CHANNEL_3 );
