Hi all,I'm using a Timer in Encoder Mode on STM32F103, using the HAL framework on STM32CubeIDE.I would like to change encoder filter feature (IC1F[3:0]: Input capture 1 filter) depending on the behaviour selected in my MCU operation mode (so IC1Filte...

Hello,I'm working on a STM32 project which use the timer in encoder mode.TIM2 of my STM32F103C8 is set in Encoder Mode, I've enabled the TIM2 global interrupt.I'm evaluating the counter at each interrupt.Prescaler is 0, Counter Period is 65535.Main c...

I'm working on a board design with a STM32F103C8. First time for me to build a PCB with STM32, I've always worked with "blue pill" boards.Not sure about BOOT wiring. The firmware will be uploaded using STM32CubeProgrammer. The board should startup us...

Hello GOmon.1,I'm using the macro below, which sets the CNT register of the timer instance to zero__HAL_TIM_SET_COUNTER(&htim3, 0);

I've tested and I can confirm changing the filter and polarity works without de-initialization. So updating the filter and polarity bit of htim->Instance->CCMR1 and htim->Instance->CCER works.I would like to change the Clock Division too, so change t...

Thank you!

Yeah! Now is getting clear.> Yes. But those signals are not directly coming from pins...So TI1FP1 or TI2FP2 are sampled at APB clock rate... means 72Mhz in my case. Right?> That's not entirely true. ARR...> That depends on what did you set in TIMx_DI...

Really thanks for clarifications.> As I've said, the main problem is interrupt latency (and the ISR execution duration). If the transitions are faster than that...That is why I'm doing the less i could in the ISR, just coping the CNT value to a 32 bi...
