Is it possible to read from multiple channels of same timer in input capture mode...?

[MSkar]

Hi ,

  My name is Midhun .I want to know is it possible to read from multiple channels of same timer in input capture mode...?

I am using Stm32f401RE Nucleo board ,Using MDK ver 5.0 on KEIL IDE.

Our project includes a multitude of optical encoder units which we used to find the position of dc motors associated with it .Is it is possible to access multiple encoder unit reading which are connected to different channels of a particular timer ,If yes how to read value by addressing the timer channel specifically using the HAL API functions..?

Yes you can use all the channels of one timer in input capture mode, you'll read the captured value from TIMx_CCRx registers. I don't use Cube, don't know the incantation for that, sorry.

You can't use the "encoder mode" (in the slave-mode controller) on other than CH1+CH2, though, if you'd intend to use that mode.

Read the TIM chapter in RM.
