And in my main file after init the timer i just lunch start like this :
MX_TIM1_Init();
HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_1);
HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_3);
With this i got an output on PA10 and PC0 but nothing on PB1 and PA7
So if i try to lunch " HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_ALL); "
I have no output on any pins...
