Problem with PWM stopping after commutation event. Hello - i'm new to STM32 MCU's (mostly have been using 8bit AVR's or OS based Raspberry Pi). I've been trying to implement a 6-step motor control (making everything from scratch as a learning experience). I picked TIM4 and TIM8 in a master-slave configuration, using complementary outputs of channel 1, 2 & 3 in TIM8. Everything is set so that PWM preloaded registers update happens in a commutation even, which is the TRGO of TIM4.void motor6Step_Init(TIM_HandleTypeDef* htim4, TIM_HandleTypeDef* htim8){
htim4->Instance->CCR1 = (TIM4_ARR>>2);
htim8->Instance->CCR1 = 0;
htim8->Instance->CCR2 = 0;
htim8->Instance->CCR3 = 0;
htim8->Instance->CR1 &= ~( TIM_CR1_CEN );
htim8->Instance->CNT = 0;
__HAL_TIM_ENABLE_IT(htim8, TIM_IT_UPDATE);
HAL_TIMEx_ConfigCommutEvent_IT(htim8, TIM_TS_ITR2, TIM_COMMUTATION_TRGI);
}
void motor6Step_Start(TIM_HandleTypeDef* htim4, TIM_HandleTypeDef* htim8){
HAL_TIM_Base_Start(htim8);
HAL_TIM_OC_
