G431 - reset counter and prescaler on input capture

[Tobe]

Is there a way to reset the counter and the prescaler via a hard event or something when an input capture happens?

I use timer 1 to have a hall interface and to drive timer 8. But there are some fluctuations, because the interrupt (where i reset counter and prescaler) is not fired at the exact time as the input capture happens.

No; but you can set input capture and TRGI to the same source (or you can set input capture upon TRGI), and then use the slave-mode controller:

I would not consider this as a "no", since it actually works ;)
