which makes it even funnier, because "responsive" has been misused many a times as well. (3988 and 3310 most responsive sensors! especially this one with the good implementation!)
edit: haha, mcu smoothing

but raw and snappy should more or less mean the same thing in this context anyway, so imo they're all on the same street when it comes to misused.. terms
for some, i guess raw could mean 1:1 movement (low jitter), rather than responsive?
pretty sure most guys using these terms are talking out of their something anyway. in 99% of the cases it's probably just the shape, weight and feet that makes them control the mouse well. yes yes, very responsive sensor dude..

snappy is maybe a word better used for buttons or switches or something, or for snapping turtles.
raw should probably not be used at all


good talk dude

thought this forum liked good mice so not sure why this has 138 pages. enjoy paying $80-100 for a mouse with a nerdy signature and bright LED's u cant turn off and have 5 dpi steps with a sensor that can have 100's of dpi steps, not to mention dat finalmouse build quality. whos actually buying this over the new logitech mouse lol?

Jude, I'm confused why you guys are doing so much work to make the mouse as raw as possible (which btw you shouldn't have to do anything with a 3360) when you used to talk about how your pros prefer smoothing and that's why you guys totally intentionally had it on the previous mice.

Also when are you going to stop listing the misleading weights of your other mice? You said well over half a year ago that you'd fix that.

Not sure what you mean by making it more raw. That's not what we are optimizing. Motion data has never been affected in the s1 from the beginning of development. We are just trying to fine tune how this happens and make sure it's optimal code. SOF is an interrupt timer from what I've been told. We are using that because it is very tight/accurate. So reports are very consistent/clean as opposed to other methods. And button polling gets to stay at 1ms with these modifications .

Turns out [there were tiny things we could further optimize even though no one would have ever known. We changed how the burst motion reads work completely, so instead of having main loop timer request motion burst reads every 1ms and then attempting to sync with usb, we modified the motion reads to integrate completely with the USB SOF interrupt.
i knew and i told you lol

SOF stands for "start of frame"
and yes it's what you want your main loop to be synchronized to. not sure about nxp's stuff, but for avr you can get the timing via an interrupt or via polling the corresponding flag (SOFI in UDINT).

Well hopefully their plan is to release multiple shapes after they finish this whole PCB thing

Then maybe they can make a lightweight high height similar to the ec. That'd be dope and would mess up zowie cause FM clicks are much better

Need to get on that rubber cable train tho

I wish all the companys would make clones of the popular shapes.

Well we found its better to get rid of our main loops request. So instead of reading motion bursts all the time and then grabbing during whatever timer or interrupt (SOF included) we instead just do a burst motion read once per SOF. And a burst motion read will always be ready in time for that frame.

yup that's how logitech does it too and it's how it should be done

now see if you can get 8khz working
