WebDec 22, 2024 · specifies the TIM Channel This parameter can be one of the following values: TIM_Channel_1: TIM Channel 1. TIM_Channel_2: TIM Channel 2. TIM_Channel_3: TIM Channel 3. TIM_Channel_4: TIM Channel 4. ChannelState. specifies the TIM Channel CCxE bit new state. This parameter can be: TIM_CCx_ENABLE or … WebHAL_TIM_PeriodElapsedCallback is never generated from a channel. It comes from the basic timer counter overflow/underflow which you start with HAL_TIM_Base_Start_IT. Channels can be started individually in different modes, say HAL_TIM_PWM_Start_IT.
STM32F439xx HAL User Manual: TIM Exported Functions
WebThe issue is with HAL_TIM_PeriodElapsedCallback () which should get called when whenever the timer has overflown and toggle an LED. The LED's configuration is correct.HAL_TIM_PeriodElapsedCallback () gets called by HAL_TIM_IRQHandler (&htim3); which is called whenever an interrupt for timer3 is fired such as when the timer overflows. WebWhat you can do is to create a queue on the interrupt to store the period. Because the sampling frequency should be at least double the PWM frequency ,you have to handle the period asynchronously (because the main loop may be slow to handle these frequencies) .I had the same issue quite some time ago but instead of a PWM I had a saw tooth with … blank point seattle crossword
Exploring the Different Modes of TIMER Operation in STM32 N2
