    Hiya well both Controllers seem to work ( I Think :) 0ne is Leonardo based and the other STM I can run all the tests but my problem is it wold be nice to know what each test was supposed to do ( sortta Text explanation ) but im looking at the wrong places to find this info ... It does Linearity and the steps test ( no Graphs yet im still working that out .. Most You tube stuff does not have test subtitles and being deaf kinda makes it hard to fill in the gaps sometimes )

    Encoders seem fine But I only have 4.7K ohm pull ups so maybe I need 10K ... but the trace on my portable scope looked nice and clean and rail to rail so will need to check connections again tomorrow .. Always appreciate feedback excuse the Pun Cheers

    If your pull ups are from 5v from Arduino and from 3.3v from stm32 too, you should put only 220 ohms only but not 4,7k.

    Wannabeflyer, have a look. https://www.isrtv.com/forums/topic/8286-fanatec-review/#comment-75034

    Step test kind of checking the speed of wheel with its response on change of direction corresponding to default 300ms signals to turn on both directions. How sharp it reacts etc. How far goes for this time. Depends on wheel base settings also. The force linearity you can find description in link above.
