Sans trop chercher, je suis tombé sur le site de oscar Liang qui est juste énorme le WAF en ANGLAIS et un élément de réponse est apparue du apparement a BF3.4
RC Smoothing Filter
RC signal gets updated regularly, if you look at blackbox log you will find “stepping” in the original RC signal. Stepping in the RC signal results in rougher running motors.
RC Smoothing filter can smooth out these stepping. It can even reduce spikes and sharp edges from rapid stick inputs, your motors will run smoother and cooler.
Previously we used a method called “Interpolation”, but it has relatively high latency. In Betaflight 3.4, we are given a new method called “Filter” which has less smoothing, but also less latency. The benefit is that the aircraft feels more responsive and connected to your sticks.
Having said that, you may or may not feel the difference, but less delay is always a good thing.
set rc_smoothing_type = FILTER
set rc_interp = AUTO
set rc_interp_ch = RPYT
If you notice a change in rapid stick response, consider adjusting “setpoint weight”, “throttle boost” and P gain to compensate.
Adjust setpoint weight, throttle boost, P gain
