STM32 General Purpose Timer : Understanding Input Capture (IC) Mode -2

[@TheOldProgramming]

In the case we are using 4 channels in input capture mode of the same timer that same HAL_TIM_IC_CaptureCallback will be called for all the channels or they can work concurrently? I mean for example if i use 4 hc-sr04 sensors having their echo pins connected to 4 ic channels of the same timer then the same HAL_TIM_IC_CaptureCallback will be called on the rising and fallling egde of the input signal? If so that means the measures of the sensors frequency will be wrong? I am sorry for the bad English :D

Its very cleary presentation. Thank you.

How will I measure the falling edge of the pulse at the same time?

[@thanhthonguyen6171]

hi, bro. I want to know maximum of the input frequency can be measured. I will use STM32F4 to measure input signal with frequency of about 30Mhz. Can it be measured? thank you!!!

[@andrebalsa203]

yes, maximum input frequency is specified at 100MHz on STM32F4XX datasheet

no videos of codes so pity
