STM32 MCUs

[Leylifer]

Hi,

I want to use input capture mode with high resolution timer(HRTIM) on stm32f334r8 microprocessor. I am sending a pulse signal over the oscilloscope. I use one of the External Event Input pins for this. I want to capture the rising edges of the pulses I send using the HRTIM_Simple_Base_Start function. However, I couldn't do that. The settings I made regarding the configuration are as attached. How can I use input capture mode with HRTIM?

Hello @Leylifer 

Referring to the RM0364. I see that the input capture mode is not defined in the chapter 22 off the ref.man (High-Resolution Timer (HRTIM)). I think that the HRTIM of the f334 doesn't support the input capture mode. 

Best regards.

capture should work - but what you wanna capture ??

you set counter free running + capture (event 5) -> seems no sense to me, you will get just random values this way.
