I am using the advanced timer TIM1 on STM32L476RG MCU. I have configured the timer in slave reset mode as given in section 30.3.26 of the reference manual. The counter resets every rising edge. I want to use this mode to measure low frequencies such ...

The reason for using the slave reset is so that the first value is always 0. Anyway if the input capture mode with DMA would give a more accurate reading then that would be the way to go. Thanks for the suggestion.

Thanks for the reply.I want to transfer the timer counter value before update. Is that even possible ?If so does this look correct ? htim1.Instance->DIER = TIM_DMA_UPDATE; DMA1_CSELR->CSELR |= (DMA_CSELR_C6S << 0b0111); HAL_DMA_Start(&hdma_tim1_up, (...

Hi , I would like to know if there is a way to use DMA to get the TIM1 advanced timer update events ? I can successfully trigger an IRQ but having problems setting a DMA to trigger on every update. I am using STM32 L4 MCU.
