Humm, I also need a scale function that runs on s32's. What we have runs on floats. OTOH, an s32-to-float in front of the whole chain, and a float-to-s32 at the output would work, but the execution time of all those floats in the middle might be a hurt on the pi. Ideally, all this should run only if conditions have changed, but I've no clue how to write an if/else/else/else/end in hal. > I suspect that you can derive up-pulse and down-pulse signals from > logic and the raw A B phases. As I had planned. But no progress yet, honeydo stuff in the way. ;) > I think I would start with a pencil and paper and a self-referencing > LUT5.

So I have noticed. :) If its low in execution time, and you wrote it, so you understand it intimately, why not? ;-) I tend to look for less complex bits and pieces I can stack up in the right sequence.
